AMPCO 21 Aluminium Bronze

•Extruded and drawn rounds & rectangular bars 
•Forgings 
•Horizontal Continuous Casted 
•Centrifugal Casted 

AMPCO®21 Aluminium Bronze is used for guide port bushings and wear strips replacing hardened steel and for some cams when no impact is involved. However, the largest single use is as die rings, inserts, forming rolls etc. in forming, bending or drawing operations, especially when stainless steel is the material being processed. 
AMPCO® 21 is also widely used as work support blades for the centre less grinding of steel rods 

The increase in the Al and Fe content results in a material in which the hard gamma 2 phase (about 400 HB) is present. By proper metallurgical control this hard constituent is uniformly distributed giving this alloy its ability to resist wear.
