B22F WORKING METALLIC POWDER; MANUFACTURE OF ARTICLES FROM METALLIC POWDER; MAKING METALLIC POWDER (making alloys by powder metallurgy C22C); APPARATUS OR DEVICES SPECIALLY ADAPTED FOR METALLIC POWDER
Introduced: September 1968
Description
B22F covers the entire spectrum of metallic powder technology, including production methods (atomization, comminution, gas or water separation), consolidation processes (sintering, hot isostatic pressing, compaction), and specialized equipment for handling metal powders. This subclass encompasses powder metallurgy techniques for manufacturing finished components and semi-finished products, as well as apparatus designed specifically for metallic powder operations. Related casting technologies are addressed in the parent class B22, while general powder handling methods appear in B01B.

CPC subdivides this area 2x more granularly than IPC with 10 additional codes.
10 codes are CPC-only extensions.
Note: 10 CPC extensions are marked as secondary classification only.
2 shared codes have differing titles between IPC and CPC.
