Metal Powder

Chromium Metal Powder

High-purity chromium for stainless-grade consumables, PM parts and diamond tools.

Where ferro chrome brings iron and carbon along with the chromium, chromium metal brings chromium and very little else. That matters in extra low carbon stainless consumables, in powder metallurgy where the final chemistry is tightly specified, and in diamond tool segments.

We supply chromium metal ground and screened to the size range your press, blend or coating requires.

Specification

Standard grades

The grades below are the standard specifications this material is traded to. We supply against your specification — tell us the grade and we will confirm what we can hold.

Typical chemical composition — Chromium Metal (%)

Grade	Cr	C	Si	Al	S	P	Fe
Standard	99.00 min	0.030 max	0.30 max	0.50 max	0.030 max	0.030 max	0.50 max
A — high purity	99.20 min	0.02 max	0.20 max	0.20 max	0.02 max	0.02 max	0.20 max
High carbon	60.00–70.00	4.00–9.00	—	—	—	—	Balance

Grade A is the aluminothermic high-purity grade. The high-carbon grade is a different material altogether — a chromium carbide unit for hardfacing electrodes, not a substitute for the low-carbon grades.

Please note. These are indicative industry-standard ranges shown for guidance. Where a grade name encodes a nominal sieve or density, that is what the designation means in the trade — the size range actually supplied, and the packing, are set to your requirement and confirmed on your order. The binding specification for any order is the one on your purchase order and the test certificate supplied with the consignment — see how we test and certify a lot. Ask us for a datasheet for the exact grade you need.

Particle Size

Mesh and micron

Size is specified separately from chemistry, and it is usually the figure that decides whether a powder works in your process. We grind and screen to the range on your order — tell us the mesh you need.

What a mesh number means

Mesh counts the openings per linear inch of the test sieve, so a higher number is a finer powder. “−100 mesh” means the material passes a 100 mesh sieve — nominally 150 micron. These apertures are the published ASTM E11 / ISO 3310-1 standard.

20 mesh: 850 µm
30 mesh: 600 µm
40 mesh: 425 µm
50 mesh: 300 µm
60 mesh: 250 µm
80 mesh: 180 µm
100 mesh: 150 µm
120 mesh: 125 µm
140 mesh: 106 µm
170 mesh: 90 µm
200 mesh: 75 µm
230 mesh: 63 µm
270 mesh: 53 µm
325 mesh: 45 µm
400 mesh: 38 µm

Where each band is used

General guidance on the ranges these industries work in, useful if you are specifying a powder for the first time. It describes the trade, not our production.

Application	Typical band	Why
Welding electrode coatings and flux	20 – 100 mesh	Coarser powders, blended into the coating slurry.
Powder metallurgy — pressing and sintering	60 – 200 mesh	Iron and copper powders for pressed parts; apparent density matters as much as size.
Thermal spray and hardfacing	100 – 325 mesh	Tighter distributions, since feed behaviour depends on it.
Metal injection moulding and additive	170 – 400 mesh	The finest bands, with close control of the distribution at both ends.

Our standard range for Chromium Metal Powder: to be confirmed — ask us and we will confirm what we hold and what we can grind to.

A note on the figures above. The sieve apertures are an exact published standard. The application bands are general industry guidance and are not a statement of what we supply — our own standard range is the line marked above, and it is confirmed against your order rather than read off a chart. Ask us for the size range you need.
