How to choose the material of battery precision metal shrapnel? 'Hardware'

The battery precision hardware shrapnel is an important part of the battery, which is made of copper, iron, stainless steel and other materials. Electroplating CT, silver, nickel. When the precision metal shrapnel of the battery installed on the conductive film is pressed, the center point of the shrapnel contacts the PCB board to form a loop, and the current passes through it. It has the characteristics of strong conductivity and good hand feeling. When choosing battery shrapnel, many friends are entangled with what material to choose battery precision hardware shrapnel. First, let’s take a look at several materials used in battery shrapnel: cold plate (that is, iron), manganese steel, brass, and phosphorus. bronze. However, which one to choose depends on the structure of the plastic case of the battery, the value of the product, and the environment in which it is used. The material usage of the battery's precision hardware shrapnel: 1. Ordinary batteries generally use cold plate nickel-plated material, and the effect of nickel-plating is very good, and the cost is also very low. 2. For products used in a humid environment, brass should be considered, but the cost will be relatively high several times. The general manufacturer of ordinary cold plate nickel plating can pass the salt spray for 72 hours without rusting after sealing the oil. Some friends think that the elasticity of stainless steel is better, but we also need to consider that the material of stainless steel is non-sticky, which means that we cannot weld or it is difficult to weld. In fact, the elasticity of manganese steel after heat treatment is similar to that of stainless steel of. 3. The material of phosphor bronze is also commonly used for this kind of products, with good elasticity, no rust, low resistance, and easy welding, but the cost of phosphor bronze is higher. Based on the above, I believe many friends are aware that the precision hardware shrapnel we choose for batteries are not exactly the same. We need to decide according to our own situation.
