In order to meet the requirements of making structural parts, it is widely used in the industry to add alloying elements to copper to make copper alloys with enhanced properties. Brass is a copper alloy with zinc as the main alloying element, which has good mechanical properties and is easy to process. It has good corrosion resistance to the atmosphere and seawater. According to the type of alloying elements contained, it can be divided into ordinary brass and special brass; according to the production method, it can be divided into press-processed brass and cast brass.
On the basis of ordinary brass, elements such as Sn, Si, Mn, Pb, and Al are added to form a copper alloy. Depending on the added elements, they are called tin brass, silicon brass, manganese brass, lead brass and aluminum brass. Ordinary pressure processed brass grades: H+ average copper content. For example: H62 means ordinary brass containing 62% copper and the rest is Zn; cast brass includes ordinary brass and special brass grades: ZCu + main element symbol + main element content + element symbol and content composition of other added elements .
Cupronickel–a copper alloy with nickel as the main alloying element. It has good cold and hot working properties, and cannot be strengthened by heat treatment. It can only be improved by solid solution strengthening and work hardening. Grade: B+ nickel content. Cupronickel grades with more than three yuan: B + the symbol of the second main added element and the number group of components except the base element copper. For example: B30 means cupronickel with a Ni content of 30%.
