Brass plate applications: It can be used for various deep drawing and bending manufacturing parts that bear force, such as pins, rivets, washers, nuts, tubes, barometers, screens, radiator parts, etc. It has good mechanical properties, good plasticity at high temperatures, moderate plasticity at low temperatures, good machinability, easy to wire and weld, corrosion resistance, and is a widely used common brass variety.

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 a single phase a, known as single-phase brass, which has good plasticity and is suitable for cold and hot pressing processing. When the zinc content is greater than 39%, there is a single phase a and a b solid solution based on copper and zinc, known as dual-phase brass, which makes the plasticity small and the tensile strength increases, only suitable for hot pressure processing. If the mass fraction of zinc continues to increase, the tensile strength will decrease, and there is no value for use. The code is represented by "H + numbers", where H represents brass and the numbers represent the mass fraction of copper. For example, H68 represents a brass containing 68% copper and 32% zinc, and Zcuzn38 represents a casting brass containing 38% zinc and the remainder being copper. H90 and H80 are single-phase, golden yellow, so they are collectively known as "golden coating", used for decorations, medals, etc. H68 and H59 belong to dual-phase brass, widely used in structural parts of electrical appliances, such as bolts, nuts, washers, springs, etc. In general, single-phase brass is used for cold deformation processing, and dual-phase brass is used for hot deformation processing.
