naval bronze and naval brass
Naval Brass, Naval Bronze - S.A.E. CA 464
The excellent strength and corrosion resistance of this alloy, together with its comparatively low cost, make it a favorite for shafting. It has fair machining qualities but is readily hot worked. Typical uses include valve stems, rivits, nuts, marine hardware and screw machine parts.
