Material selection and main functions of hardware shrapnel

Among the many metal stamping parts, the use rate of metal shrapnel is relatively high. It is mostly used in switches. Through the conductivity of the metal shrapnel, it serves as a bridge between the user and the product. Today we will focus on explaining its material selection and main functions.　　How to choose the material of the hardware shrapnel? 　　 Generally speaking, the hardware shrapnel needs to determine the final material according to the purpose and performance of the shrapnel.　　 The frequency of use is relatively high, and the pressure is relatively large, then carbon steel, spring steel or high-hardness stainless steel can be used as raw materials, but it needs to be quenched after forming. Quenching can reduce the carbon content in the material. It is required to have good acid and alkali resistance, good weldability, and strong conductivity, then copper processing can be used. At present, the more common hardware shrapnel produced from copper materials include phosphor copper shrapnel and beryllium copper shrapnel, which can be processed on the surface Various electroplating to increase performance. The hardware shrapnel used in electronic digital products needs to be processed with a certain fixed grade/hardness copper material when selecting materials, such as red copper, brass, bronze, phosphor copper, beryllium copper, etc., the hardware shrapnel processed by these materials With excellent accuracy and conductivity.　　What are the main functions of hardware shrapnel? 　　1. Control mechanical movement, such as valves in some mechanical equipment, clutch switch shrapnel and so on.　　2. It can effectively absorb shock and vibration. These hardware shrapnels are needed under trains and cars to reduce the vibration and shock generated during driving. 　　3. The storage capacity and output energy can be used as power, which will be used on clocks and watches.
