How to write the chemical formula of brass

Copper-zinc alloy: plain brass It is an alloy composed of copper and zinc. When the zinc content is less than 39%, zinc can dissolve in copper to form single phase a, called single-phase brass, which has good plasticity and is suitable for hot and cold pressure processing. When the zinc content is more than 39%, there are single phase a and b solid solution based on copper and zinc, called double-phase brass.
