　　The battery shrapnel is punched out by metal. Don't underestimate a small battery shrapnel. It is the medium connecting the battery and the wire. The material of the battery shrapnel has a certain influence on the battery. Generally, the material of the battery shrapnel has a cold plate (ie We say iron), manganese steel, phosphor bronze, brass. Many customers will be very tangled when choosing the material of the battery shrapnel, and they have no way to start. Then the editor will introduce to you which materials are good for the battery shrapnel?

What is the best material for the battery shrapnel?

The specific choice of these materials depends on the plastic shell structure of the battery, the value of the product and the use environment.

Ordinary hardware batteries are generally nickel-plated with cold plates. After nickel-plating, the effect is very good and the cost is very low. If the product is used in a very humid environment, it can also be considered to be made of brass, which will cost several times higher. The ordinary cold plate nickel-plated in our factory can pass through salt spray for 72 hours without rusting after oil sealing.

Such shrapnel-type battery springs are generally made of springs or phosphor bronze, and some customers may think that stainless steel is better for elasticity. In fact, the elasticity of manganese steel after heat treatment is similar to that of stainless steel.

　　Phosphor bronze is also commonly used for this type of product, with good elasticity, no rust, low resistance, and easy welding. Some customers also use beryllium copper aging for customers with high elasticity and fatigue resistance. It is the best choice, of course. , its cost is also spring steel, stainless steel, phosphor bronze, beryllium copper and the cost varies.

The above is about what material is good for battery shrapnel: http://www.bosiwj.com/mp-05.html

I believe that after reading it, you will understand what material is suitable for battery shrapnel. In fact, the choice of which battery shrapnel material is mainly depends on the changes in the use environment. I hope this knowledge can help you.
