Pure copper is a rose-red metal, and the surface becomes purple after a copper oxide film is formed on the surface, so industrial pure copper is often called red copper or electrolytic copper. Fire refining can obtain 99-99.9% pure copper, and electrolysis can make the purity of copper reach 99.95-99.99%. The density is 8-9g/cm3 and the melting point is 1083°C. Pure copper has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity and is commonly used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses and aviation instruments; it has excellent plasticity and is easy to heat Pressure and cold pressure processing can be made into copper materials such as tubes, rods, wires, strips, strips, plates, and foils. There are two types of pure copper products: smelted products and processed products. The product specifications are complete, the price is favorable, the packaging is intact, the copper is pure, the straightness is good, the inventory is large, and the material certificate and SGS report can be provided.
Red copper is relatively pure copper. It fully demonstrates the ductility, conductivity and corrosion resistance of metallic copper, among which ductility is an important feature of copper decoration. Red copper has a high melting point and is not easy to cast. Its good ductility makes up for this shortcoming, so it can be easily processed into various shapes and patterns. The dark red metallic luster makes it have a calm and noble quality while expressing a sense of modernity. It is the most commonly used material in copper ornaments.
