Brass is a yellow alloy of copper and zinc. It has excellent mechanical properties and strong wear resistance. When zinc content is less than 35%, zinc can dissolve in copper to form single phase A, called single phase brass, good plasticity, suitable for hot and cold processing.

When the zinc content is 36%~46%, there is a single phase and copper zinc based β solid solution, called dual-phase brass, β phase makes the plasticity of brass decreased and the tensile strength increased, only suitable for hot pressure processing.

When zinc content > At 46%, the alloy becomes too hard and brittle to be useful.

The brass grade is represented by "H + number", where H represents brass and number represents the mass fraction of copper. Such as our commonly used environmental protection copper H59, H62 copper.
