Copper tube is a copper alloy tube, also known as brass tube. It consists of a mixture of copper and zinc, usually 63% copper and 37% zinc. Copper tubes have good plasticity and corrosion resistance, so they are widely used in the manufacture of pipes, fittings, instruments and decorations. It also has good electrical and thermal conductivity, so it is also used in the manufacture of wires, cables, and heat sinks, among others.Copper tubes have good processing properties and can be cold and hot processed, such as stretching, rolling, extrusion, etc., so they can be processed and customized according to different needs.
