Bronze / Brass / Copper
Free Machining Brass BS EN 12164
Description:
Free machining brass bar had lead added to the composition to significantly improve machinability. While free machining brass has excellent hot working abilities, cold working is poor and not recommended. It can, however, be knurled if required.
Soldering of free machining brass is excellent and brazing is good but all other welding methods are not advised without consultation with a welding professional.
Typically supplied in round bar, hexagon bar, square bar and flat bar. Typically used for high speed machined components.
