ASTM A904-26

Annotation of standard text ASTM A904-26 :

This specification covers the magnetic property requirements of 50 nickel-50 iron soft magnetic parts fabricated by powder metallurgy techniques in the sintered or annealed conditions, intended for parts that require high magnetic permeability, high electrical resistivity, low coercive field strength, and low hysteresis loss. This specification does not cover parts produced by metal injection molding. Parts shall be tested and adhere to the chemical composition, sintered density and coercive field strength requirements listed in this specification. Appendices contain information on typical magnetic properties and heat treatment.
