With pure copper or copper alloy made into a variety of shapes including bar, wire, plate, strip, strip, tube, foil, collectively referred to as copper. There are rolling, extruding and drawing methods for copper, hot-rolling and cold-rolling for copper plate and Strip, cold-rolling for Strip and foil, extruding and drawing for Tube and Bar, and drawing for wire.

Copper can be divided by composition into:

BRASS: an alloy of copper and zinc. 

White Copper: an alloy of copper and nickel

Bronze: An alloy of copper and other elements except zinc and nickel, chiefly tin bronze and aluminum bronze

Red Copper: pure copper, also known as Red Copper, pure copper density of 8.96, melting point of 1083 °C. With good conductivity and thermal conductivity, excellent plasticity, easy to hot and cold pressure processing, a large number of wires, cables, brushes, EDM special copper products require good conductivity.

(1)Copper Rod is a kind of Non-ferrous Metal Rod, which has good processability and high conductivity. Mainly divided into brass Rod (copper zinc alloy, cheaper) , copper Rod (higher copper content) . Copper Rod Classification: Aluminum Bronze Rod, Tin Bronze Rod, Silicon Bronze Rod, beryllium bronze plate, brass plate, cupronickel plate, red copper plate, tungsten copper plate, oxygen-free copper plate, copper plate of various materials.

(2)Copper pipe also known as Red Copper Pipe. A type of Non-ferrous metal, which is a pressed and drawn seamless tube. Copper pipe with strong, corrosion-resistant characteristics, and become the modern contractor in all residential commercial housing water pipes, heating, refrigeration pipe installation preferred. Copper pipe is the best water supply pipe.

4. Copper wire has good conductivity, heat conduction, corrosion resistance and processing properties, can be welded and brazed. The trace oxygen has little influence on the conductivity, heat conduction and processing, but it is easy to cause "hydrogen disease" , so it is not suitable for processing (annealing, welding, etc.) and using at high temperature (such as & GT; 370 °C) in reducing atmosphere.
