Metal shrapnel stampingis an important part of the switch. With the continuity of metal shrapnel, it plays the role of high-quality switching between the operator and the product. 30 years ofcustom processing of precision metal stamping parts, customers customize various complex precision metal shrapnel according to customer requirements. Next, we will introduce the selection of materials for metal shrapnel stamping parts.

In general, the material of metal shrapnel is used to determine the use and performance of the shrapnel. For example, it needs the elasticity of the body. High frequency of use and high pressure. Spring steel, carbon steel or high hardness stainless steel are generally used. Heat treatment and quenching after forming, to reduce the carbon content by increasing the hardness and improve the service life of the shrapnel; if you want to achieve easy welding, acid and alkali resistance, improve electrical conductivity and other physical properties, you must use copper to process the shrapnel, such as phosphorus copper shrapnel, beryllium copper shrapnel, etc.Can be done byplating（gold plating, silver plating, nickel plating, tin plating, etc.) and other surface treatment methods; Moreover, for digital products such as electronic communications, the main process function requirements are mainly reflected in the precision, conductivity and solderability. Therefore, when processing shrapnel products with copper materials, certain fixed grades of hardness copper materials are generally specified, such as phosphor bronze, beryllium copper, purple copper, brass, bronze, etc.
