C69700
C69700 brass is a brass alloy primarily designed for initial processing into wrought products. It is commonly provided in the H04 temper, which means it has undergone full hardening. This brass alloy possesses a moderately low melting point and exhibits relatively high tensile strength when compared to other wrought brasses.
