Characteristics Of Copper

Pure copper is a rose-red metal, which is purple after forming a copper oxide film on the surface, so industrial pure copper is often called copper or electrolytic copper. 99-99.9% pure copper can be obtained by fire refining, and the purity of copper can reach 99.95-99.99% by electrolysis. The density is 8-9g/cm3, and the melting point is 1083 °C. Pure copper has good 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, aviation instruments, etc.; It has good plasticity, easy to be processed by hot pressing and cold pressing, and can be made into pipes, rods, wires, strips, strips, plates, foils and other copper materials. 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.
Copper is the purer form of copper. It fully expresses the ductility, conductivity and corrosion resistance of metallic copper, of which ductility is an important feature of copper jewelry. Copper has a high melting point and is not easy to cast, but its good ductility makes up for this disadvantage, so it can be easily processed into a variety of patterns. The dark red metallic luster makes it express a sense of modernity while also having a calm and noble quality, and is the most commonly used material in copper jewelry.
