Distribution box shell processing is a metal processing process involving multiple links and fine operations. The material selection of distribution box shell is a key link in the manufacturing process. Common materials include stainless steel, carbon steel, aluminum, etc. Each of these materials has its own characteristics: 1. Stainless steel: has strong corrosion resistance and is suitable for highly corrosive environments. 2. Carbon steel: has high strength and is suitable for high pressure environments. 3. Aluminum: is light in weight and has good electrical conductivity, and is suitable for low pressure environments.
