PRODUCT INTRODUCTION

Pure copper is a rose-red metal, and it turns purple after a copper oxide film is formed on the surface, so industrial pure copper is often called red copper or electrolytic copper. 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 often used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses, aviation instruments, etc.; excellent plasticity, easy to heat Pressed and cold pressed, it can be made into copper materials such as pipes, rods, wires, strips, strips, plates, foils, etc.

APPLICATIONS

The use of pure copper is much wider than that of iron, and a large amount of copper is used in the electrical industry every year. Pure copper is mainly used to make electrical equipment such as generators, bus bars, cables, switchgears, transformers, etc. Oxygen in copper (a small amount of oxygen is easily mixed in copper smelting) has a great influence on electrical conductivity, and copper used in the electrical industry must generally be oxygen-free copper. Pure copper is also mainly used in the production of motor short-circuit rings, electromagnetic heating inductors, and high-power electronic components, terminal blocks and the like. Pure copper is also used in furniture and decorations such as doors, windows, and handrails.
