Copper Strip
Copper with a purity of 99.5% to 99.95% is commonly referred to as pure copper or red copper due to its reddish hue. The primary composition consists of copper and silver, with trace amounts of elements such as phosphorus, bismuth, antimony, arsenic, iron, nickel, lead, tin, sulfur, zinc, and oxygen.
This high-purity copper is widely used in the production of electrical components, high-grade copper alloys, and copper-based materials due to its excellent conductivity and durability.
Pure copper is classified into T1, T2, and T3 grades. We collaborate with specialized copper manufacturers to supply aluminum-copper alloys and brass in various forms, including sheets, rods, tubes, and wires.
