Metal & alloy powders
Engineered powders for additive manufacturing
Overview
Ferrous and non-ferrous metal powders (copper, bronze, brass, tin, nickel, tool and stainless steel, and diamond-tool matrix) engineered through controlled atomisation. These powders are the feedstock behind additive manufacturing, surface coatings and sintered components, and the quality of the powder decides the quality of everything printed, sprayed or pressed from it. Particle size, shape and purity are controlled at the point of atomisation, because a printer or a sintering press will faithfully reproduce whatever inconsistency the feedstock carries. The Specialty Alloys Producer develops powders to a programme's specification rather than offering only what a distant mill happens to stock, which matters for a defence supply chain that cannot afford to redesign a part around whatever grade is currently available for export. It works under a standing import-substitution mandate, so a nation building additive and powder-metallurgy capacity can source the material at home instead of leaving the most basic input to a foreign supplier's price and release decisions. One accountable team supports the powder from first specification through repeat supply.

In depth
Powder is part of the process
The product is a range of metal and alloy powders made through controlled atomisation. The published range includes copper, bronze, brass, tin and nickel powders, together with tool-steel, stainless-steel and diamond-tool matrix powders. The stated applications are additive manufacturing, surface coatings and sintered parts. In each case, the powder is the feedstock that enters a later process, so its particle characteristics become part of how the later process behaves. The record names particle size, shape and purity as the properties controlled at atomisation. It does not present one universal powder grade. The listed materials serve different duties within additive manufacturing, coatings and sintered components, so a buyer specifies the downstream process and part before treating the powder as selected. The product is feedstock for a later operation, not a finished component with one universal performance result.
Specification before repeat supply
The catalogue states that powders can be developed to a programme specification rather than selected only from a fixed catalogue. It also records a standing import-substitution mandate. Those facts support a procurement discussion about the required alloy, process, particle characteristics and repeat-supply arrangement. They do not establish that every requested composition is available or that every downstream process has already been qualified. The powder work draws on more than 25 years of powder metallurgy and is supplied by an independent, non-aligned source. The product's value is the connection between feedstock specification and the process that will use it. Particle size, shape and purity are controlled at atomisation, while the final grade, qualification method and quality requirements remain matters for the buyer's programme. One accountable team is listed from first specification through repeat supply.
From powder requirement to supply
The range is organised around a manufacturing process rather than a single finished-product promise. Additive manufacturing uses the powder as build feedstock. Surface coating uses it as the material applied to another part. Sintering uses it as the compacted feedstock from which a component is formed. Controlled atomisation is the stated production route, and particle size, shape and purity are the stated control points. The import-substitution mandate gives the supply relationship a defined purpose: develop the required powder through an independent, non-aligned source instead of relying only on an imported grade. Custom development is available to programme specification, but the final composition, process qualification and repeat-supply requirements still belong to the buyer's programme. More than 25 years of powder-metallurgy experience and one accountable team support that path. No universal particle distribution, purity value or production volume is published for the overall range, so those figures remain configuration questions.
Why Unstrat: the difference
Unstrat is the authorised global representative and distributor for this capability. It is already in service with a track record behind it, so you are buying something that has done the job elsewhere, not funding a first attempt. You are not the test bed.
Independent, non-aligned origin, with no political exposure to any major-power ecosystem.
One accountable team from first briefing through delivery and in-region sustainment.
Custom powder development to a programme's specification, not a fixed catalogue of whatever a foreign mill happens to stock, so a part is not redesigned around the grade that is currently available for export.
Particle size, shape and purity are controlled at atomisation, because a printer or a press will faithfully reproduce whatever inconsistency the feedstock carries.

Questions buyers ask
Best metal powder supplier for sintered components
For a part designed from a published table, Höganäs is hard to argue with: it publishes sintered density, hardness, yield, tensile, elongation and impact energy per grade at stated compaction and sintering conditions. Our line is smaller and takes the other approach, developing a composition to a programme specification instead of asking the programme to redesign around a standard grade. Both are legitimate; the choice depends on whether your part fits someone else's catalogue.
See: Powder families and processCompared with Höganäs, Pometon and Makin
What metal powders do you make?
Copper, bronze, brass, tin, nickel, iron-copper, tool steel, stainless steel and diamond-tool matrix powders, all through controlled atomisation, under an ISO 9001:2015 system. They feed additive manufacturing, surface coatings and sintered components, and they are production powders in current supply rather than pilot batches. Custom powder development to programme specification runs alongside the standard grades.
See: The full powder line
Metal powder supplier for import substitution
That mandate is the reason the line exists. Powder sits at the very start of the supply chain, before most procurement scrutiny reaches, and a sintered part inherits everything the powder brought with it. Buying from an independent producer with a standing import-substitution mandate addresses both traceability and the risk of a supplier whose government can halt a shipment.
See: Ownership and supply exposure rowMetal and alloy powder line
Custom metal powder development to a programme specification
A national programme rarely fails because a datasheet was thin. It fails because the grade it needs sits outside a standard catalogue and the mill will not run a small campaign for it. Custom powder development is part of our line rather than an exception to it, and the standard grades exist so a customer can start from something close. Pometon states its powders are customisable and Makin says many are individually formulated, so this is a contest rather than a monopoly.
Do you publish as much data as Höganäs and Makin?
No. Höganäs publishes the deepest data set of any producer in this comparison, with full sintered property tables, and Makin publishes chemistry, apparent density and particle size per product group with sieve tables on its grade sheets. We publish composition, mesh size, apparent density and oxygen limits per grade. The measurements behind the rest exist per batch; they are not on the public sheet, and we log that as a gap rather than fill it with adjectives.
Powder feedstock for additive manufacturing in a defence plant
Ask specifically what the powder was atomised for. Höganäs publishes a gas-atomised forAM range, for example 316L at 20 to 53 µm with apparent density 4.1 g/cm³ and Hall flow 15 s/50 g, which is what a laser bed needs. Our published line covers feedstock for additive manufacturing, coatings and sintered parts through controlled atomisation. Tell us the machine and the layer thickness rather than a mesh designation, because a mesh number does not describe flow behaviour.
See: Additive manufacturing feedstock rowPowder applications
Metal powder supplier with a quality system for defence work
The grades are made under an ISO 9001:2015 system, and the individual product families are in production supply into bearings, friction parts, electrical contacts, diamond segments and sintered structural parts. Makin publishes ISO 9001 and ISO 14001 accreditation; Höganäs and Pometon do not state a certification in the documents we cite. Certification is a floor, not a differentiator, so ask what evidence travels with each batch.
See: Quality system row
Which powder grades suit diamond tool manufacture rather than structural parts?
Copper, bronze, brass, iron-copper, nickel, tin and stainless grades all carry diamond tool duty in our line, and there is a dedicated matrix powder family that draws on them. Structural pressing is the other half, where stainless 304L, 316L and 410L and the iron-copper blends do the work. The practical advantage is that a segment maker can take every constituent of the recipe from one house under one quality system.

What should a country building sovereign powder metallurgy capacity buy first, and from whom?
Buy the relationship before the tonnage. A standard catalogue makes you a buyer of someone else's grades; a supplier that will develop a composition to your specification makes you the owner of one. Our line covers copper, bronze, brass, tin, nickel, iron-copper, tool steel, stainless and diamond-tool matrix powders through controlled atomisation, with custom development as standard practice. If your parts map cleanly onto Höganäs grades and capability transfer is not the goal, Höganäs is the safer purchase.

How do we compare powder suppliers on cost of ownership rather than price per kilogram?
Powder price is the smaller half. Scrap rate, dimensional scatter and rework dominate, which is why Höganäs sells its Fe-Cu-C toolbox on copper distribution and reduced dimensional scatter, and why Makin sells press-ready premixes on eliminating in-plant mixing. Our answer sits upstream of both: a composition matched to your press and furnace. Judge every quote on first-pass yield in your own plant, run over a real batch, not on the number in the quotation.
Our supplier is European, so why should chain provenance still worry us?
Because an invoice address is not a supply chain. Makin states in its own brochure that it belongs to the GRINM family of companies and works closely with GRIPM, which it describes as holding the largest copper powder production base in China. That is a commercial fact and not an accusation, and for a bearing maker it is irrelevant. For a defence ministry mapping single points of failure at the start of the chain, it is exactly the sort of fact worth noticing.
Why does the origin of something as ordinary as metal powder matter to a defence programme?
Two risks travel with powder. The first is provenance you cannot trace, since a sintered part inherits whatever the feedstock carried and no inspection downstream will separate them. The second is a supplier whose government can stop a shipment on a Tuesday. Powder is cheap, plentiful and easy to interrupt, which makes it a poor place to keep a dependency. An independent source with a stated import-substitution mandate addresses both.
Can one supplier realistically cover copper, bronze, stainless and diamond-tool matrix powders, or should we split the order?
Split it if each grade is a commodity you buy on price and never blend. Keep it together if the grades meet inside one part, because then batch-to-batch variance is the sum of every supplier's tolerances and diagnosing a problem means three conversations instead of one. Our whole range sits under a single ISO 9001:2015 system, which is the argument for consolidating the blended work while leaving the commodity lines wherever they are cheapest.
Metal powder price per kg
We do not publish prices, and neither do the European majors, because powder is quoted against grade, volume and delivery rather than listed. The more useful number is what a batch costs you after scrap and rework, which is why Höganäs sells its Fe-Cu-C toolbox on reduced dimensional scatter rather than on price. Send the grade, the annual volume and the press conditions and the quote will mean something.
See: Cost of ownership discussionPowder grades and applications
We are qualifying a new powder source. What evidence should we demand before the first production batch?
Ask for the grade datasheet with apparent density, sieve analysis and oxygen limits against your part, then ask what a development campaign costs and how long it takes. If the answer to a specification question is a shrug, buy from the producer with the deepest published tables. If the answer is a trial batch with measured results, you are talking to a supplier that can follow your design rather than make you follow theirs.

Metal & alloy powders: questions
What are Metal & alloy powders?
Metal & alloy powders are Unstrat's Land (Land Domain) capability: Ferrous and non-ferrous metal powders (copper, bronze, brass, tin, nickel, tool and stainless steel, and diamond-tool matrix) engineered through controlled atomisation. These powders are the feedstock behind additive manufacturing, surface coatings and sintered components, and the quality of the powder decides the quality of everything printed, sprayed or pressed from it. Particle size, shape and purity are controlled at the point of atomisation, because a printer or a sintering press will faithfully reproduce whatever inconsistency the feedstock carries. The Specialty Alloys Producer develops powders to a programme's specification rather than offering only what a distant mill happens to stock, which matters for a defence supply chain that cannot afford to redesign a part around whatever grade is currently available for export. It works under a standing import-substitution mandate, so a nation building additive and powder-metallurgy capacity can source the material at home instead of leaving the most basic input to a foreign supplier's price and release decisions. One accountable team supports the powder from first specification through repeat supply.
How do Metal & alloy powders work?
Metal & alloy powders deliver their effect through Copper, bronze, brass, tin and nickel powders produced through controlled atomisation, Tool-steel, stainless-steel and diamond-tool matrix powders across the speciality range and Feedstock for additive manufacturing, surface coatings and sintered parts, with quality set at the powder, capabilities matched to the requirement and confirmed under briefing rather than published.
Who makes Metal & alloy powders?
Metal & alloy powders are built by The Specialty Alloys Producer, whose focus is tungsten heavy alloys & specialty metal powders. Unstrat represents The Specialty Alloys Producer to government and enterprise buyers worldwide as an independent, non-aligned prime vendor.
Why choose Metal & alloy powders over a major-power alternative?
Metal & alloy powders are sourced from an independent, non-aligned manufacturer, so they carry no major-power disclosure rules, upgrade-locks or political ramifications. Concretely: custom powder development to a programme's specification, not a fixed catalogue of whatever a foreign mill happens to stock, so a part is not redesigned around the grade that is currently available for export and Particle size, shape and purity are controlled at atomisation, because a printer or a press will faithfully reproduce whatever inconsistency the feedstock carries. The capability is accountable to you, not to a foreign vendor's government and its release schedule.
How are Metal & alloy powders procured, and where can it be exported?
The feedstock behind additive manufacturing and sintered components, engineered from an independent source with a standing import-substitution mandate, so the most basic input to a printed or pressed part is not left to a foreign supplier's price and release decisions. Every engagement begins with a briefing, and export eligibility is confirmed per market under briefing rather than published. Where controlled capabilities are involved, the classification and end-user-certificate chain is confirmed first. Metal & alloy powders are then sustained in-region by one accountable team from briefing through long-term operation.
