Metal shrapnel stamping parts are an important component of switches. With the continuity of metal shrapnel, it plays a role in high-quality switching between the operator and the product. Yiwei Precision has been engaged in customized processing of precision Metal Stamping parts for 30 years. Customers can customize various complex precision metal spring pieces according to their requirements. below. Yiwei Precision will introduce the material selection of metal bullet stamping parts.

Generally speaking, the material of metal shrapnel is determined based on its purpose and performance. For example, it requires the elasticity of the body. High frequency of use and high pressure. Generally, spring steel, carbon steel, or high hardness stainless steel are selected. After forming, heat treatment and quenching are carried out to increase hardness, reduce carbon content, and improve the service life of the shrapnel; If physical properties such as easy welding, acid and alkali resistance, and improved conductivity are to be achieved, copper must be used to process spring plates, such as phosphor copper spring plates, beryllium copper spring plates, etc., which can be treated by electroplating (gold, silver, nickel, tin, etc.) and other surface treatment methods; Moreover, for digital products such as electronic communication, the main process functional requirements are mainly reflected in precision, conductivity, and weldability. Therefore, when processing shrapnel products using copper materials, it is generally specified to use copper materials with certain fixed hardness levels, such as phosphor copper, beryllium copper, purple copper, brass, bronze, etc.
