2 Types :HardH) and Soft (A)
FSH Compared processing speed 10 ~25% faster than FBH 
FKH
FKA
It is the new alloy wire which added an Al element. Since high temperature intensity is high in addition to improvement in tension strength, use with high tension is possible.
FAZ The zinc coating was given to the surface, and the highly conductivity copper alloy is a center material. It is the best for high speed, high accuracy, and microfabrication.
