How to select metal materials for the performance of hardware shrapnel in metal stamping parts? We all know that in hardware stamping parts, hardware shrapnel is a product that we use more. Hardware shrapnel will generally determine the material of the shrapnel according to the use and performance of the shrapnel, then how to select metal materials for the performance of the hardware shrapnel to analyze the following:
1. for example, if the use of physical resilience is relatively high, the pressure is larger, then the general choice is to use spring steel, carbon steel, or high-hardness stainless steel. After forming heat treatment quenching, reduce its Carbon steel stampings, by increasing the hardness to increase the press life of its shrapnel!
2. if you need to achieve easy welding, acid, and alkali resistance, increase electrical conductivity, and other physical properties, use copper to process shrapnel, such as phosphorous copper shrapnel, and Beryllium Copper Flat Spring. It can be achieved by surface treatment methods such as electroplating (gold, silver, nickel, tin, etc.).
3. mobile phone shrapnel is characterized by: conductive shrapnel, because of the use of different fields, so the shape is different, is the need to open stamping. After the metal sheet is made into shrapnel by the mold, it is made with physical resilience. If the frequency of use is higher, the pressure is larger. One side is the choice of spring steel or stainless steel. After forming, heat treatment quenching reduces its carbon content, and increases the pressing service life of its shrapnel (i.e. fatigue resistance) by increasing the hardness. If the use environment is special, it can be electroplated in the process of shrapnel processing to achieve easy welding, acid, and alkali resistance, increase electrical conductivity, and other physical properties. Such as mechanical shrapnel, mobile phone key shrapnel, battery shrapnel, and so on.
4. in addition to electronic communications and other digital products, the main process performance requirements are mainly reflected in the accuracy, electrical conductivity, and weldability. Therefore, the use of copper to process shrapnel products is generally specified to use a fixed grade/hardness of copper, such as phosphor copper, beryllium copper, copper, Brass Sheet Stamping Part, bronze, etc.
