bedra5800
Regular Brass
Characteristics:
bedra5800 is a copper-zinc alloy brass, characterized by its lead-free composition and good machinability. It is primarily used as a cost-effective replacement for conventional lead-containing machining brasses, especially in applications where high mechanical properties and corrosion resistance are not critical.
Typical applications:
It can be applied to all deep drawing and bending stressed parts, such as pins, rivets, washers, nuts, conduits, barometer springs, screens, radiator parts, and others.
