Copper tube is also called purple copper tube. One kind of non-ferrous metal pipe is pressed and drawn seamless pipe. Copper pipe has the characteristics of good conductivity and thermal conductivity. It is the main material for conductive fittings and heat dissipation fittings of electronic products, and has become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. The copper pipe has strong corrosion resistance, is not easy to oxidize, and is not easy to react with some liquid substances, so it is easy to bend.

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.
