Metal stamping parts, how to choose metal for the performance of metal shrapnel
 
Hardware shrapnel is a product that we use a lot in the metal stamping parts. The shrapnel generally determines the material of the shrapnel according to the purpose and function of the shrapnel. It is like that the frequency of physical resilience is higher and the pressure is higher. Generally choose spring steel, carbon steel or high hardness stainless steel. After forming, it is heat-treated and quenched to reduce its carbon content and increase the pressing life of its shrapnel by increasing its hardness.
If you need to achieve easy welding, acid and alkali resistance, increase electrical conductivity and other physical functions, use copper to process shrapnel, such as phosphor copper shrapnel, beryllium copper shrapnel. It can be achieved by surface treatment methods such as electroplating (gold, silver, nickel, tin, etc.).
Metal stamping parts
The characteristics of mobile phone shrapnel are: with conductive shrapnel, because the use field is different, so the shape is different, it needs to be made by stamping. After the metal sheet is made into a shrapnel through a mold, it has physical resilience. If the frequency of use is higher, the pressure is greater. One side is to choose spring steel and stainless steel. After forming, it is heat-treated and quenched to reduce its carbon content and increase the pressing life of its shrapnel (that is, anti-fatigue) by increasing the hardness. If the use environment is special, electroplating can be done in the process of shrapnel processing to achieve physical functions such as easy welding, acid and alkali resistance, and increased conductivity. Such as mechanical shrapnel, mobile phone button shrapnel, battery shrapnel, etc.
Furthermore, for digital products such as electronic communications, the main process performance requirements are mainly reflected in accuracy, conductivity, and weldability. Therefore, the use of copper to process shrapnel products is generally specified to use a fixed grade / hardness copper, such as phosphor copper, beryllium copper, copper, brass, bronze, etc.
