J1 copper content in the range of 0.8-1%;

Copper content of J3 is in the range of 0.4-0.8%;

The copper content of J2/J5 is in the range of 0-0.4.

The copper content determines two factors of the product: rust prevention ability and product toughness. The higher the copper content, the stronger the rust prevention ability and toughness, the more suitable for deep processing, stretching and other products. The product price is also proportional to the copper content of the product, the higher the copper content, the more expensive the price. Stainless steel pipe with high copper content is more suitable for making stainless steel products of different shapes
