It is one of the widely used ordinary brass varieties. Used for the loaded parts made of a variety of deep stretching and bending stress such as pin, rivets, washers, nuts, conduit, barometer spring, screen mesh, radiator parts,etc. Features: Brass sheet is mainly used for riveting,cutting tools and all kinds of precision parts. Having good mechanical properties and hot plasticity as well as good machinability, the sheets are easy to weld, and it has corrosion resistant, but easy to produce corrosion cracking. Popular for DIY, arts and crafts, hardware parts, musical instruments, electrical, enameling, and jewelry making. Copper will naturally patina and has sharp edges. Please handle with care.
