Copper Plate

Red copper plate is a kind of copper material with excellent functions and very convenient production. It has 

good mechanical properties, good plasticity in hot state, acceptable plasticity in cold state, good machinability, 

easy fiber welding and welding, corrosion resistance, However, it is easy to cause corrosion and cracking, and 

it is cheap. It is a common red copper variety that is widely used.

1. Smelting. The electrolytic copper with a purity of more than 99.9% is put into the melting furnace for 

high-temperature melting, and pre-furnace analysis, spectral analysis and chemical analysis are carried out 

to ensure that the chemical composition of the raw materials for high-precision red copper plates reaches 

the national standard.

2. Production of ingots. The semi-continuous casting process is used to form the ingot.

3. Hot rolling is carried out. At this moment, the billet is not cooled after heating, the surface is rough, the 

internal structure is loose, and the state is soft. After each rolling, the surface must be milled to prevent 

impurities from entering the material during processing. The formation of products with pores or peeling 

occurs.

4. Annealing. After hot rolling, the raw material is annealed, and then hot rolling, cold rolling, annealing, 

pickling and other processes are carried out. Through repeated processing, and then rolling, the severity 

of the processing force determines the condition value of the copper sheet, and finally By finish rolling, 

the desired thickness is achieved.

5. Leveling treatment. Make the surface of the copper plate flat without waves.

Advantages

1. Good electrical conductivity, thermal conductivity, corrosion resistance and processing performance: it 

contains less impurities that reduce electrical conductivity and thermal conductivity, and trace oxygen has 

little effect on electrical conductivity, thermal conductivity and processing properties.

2. Light weight, good flexibility and easy construction.

3. It has good corrosion resistance and can ensure the waterproof effect of the tunnel for a long time. Good 

mechanical properties: good plasticity in hot state, acceptable in cold state.

Copper plate: thickness: 0.8-8 mm, width: 20-600 mm, length: below 500-2500 mm, state: Y, Y2, M, Y4 can 

also be customized according to customer requirements.

Copper strip: thickness 0.1-4.0 mm, width 12-600 mm, status: Y, Y2, M, Y4 can also be customized according 

to customer requirements.

The copper content of red copper T2 is greater than or equal to 99.90%, and the conductivity is more than

 56%; The copper content of red copper T3 is greater than or equal to 99.70%, and the conductivity is about 45%; 

the quality meets customer requirements, and it is an important environmental protection material for electrical 

appliances.

Application

Widely used in high and low voltage electrical appliances, hardware, decoration, locks, automobiles, machinery, 

electronics, instrumentation and transformer shielding, etc.;
