Metal powder grades and compositions · five families · 29 grades
Metal powder grade table: all 29 grades
Composition, particle size, theoretical density and hardness for all 29 standard grades, in five tables, one per family.
Figures checked October 2026.
Reading the tables
T.D. is theoretical density in g/cc. # is the mesh number, so −325# means the powder passes a 325-mesh sieve. Bal is balance, the metal that makes up the rest, and – means not specified. The cobalt-chromium and stainless particle sizes are in micrometres (µm).
Any part of a code. “SS4” finds the stainless 410, 410L, 420 and 431 grades.
