Copper is a widely used metal that is known for its excellent electrical conductivity, thermal conductivity, and corrosion resistance. Copper products come in various grades, which indicate the specific composition and properties of the alloy. Here are some common copper products and their corresponding grades
Overall, the specific grade of copper product that is chosen depends on the specific application requirements, such as conductivity, strength, corrosion resistance, and other mechanical properties.
