The cable materials and the performance

Information Source:Henan Huadong Cable Co., Ltd Release date:2014-03-17

The cable conductor materials are metals, Huadong cable Co., Ltd metal materials commonly used are mainly copper, silver, aluminum, gold, nickel, iron (steel), zinc, tin and so on. Following a brief introduction of the metal material and its performance!

Copper
The conductivity after the silver, gold, silver thermal conductivity after; corrosion resistance, no magnetism, good plasticity, easy welding, a wide range of uses. Copper alloy is mainly in order to improve the wear resistance of copper, and the mechanical and physical properties of corrosion resistance.

Silver
Metallic conductivity and thermal conductivity, good corrosion resistance and oxidation resistance, easy welding; mainly used for coating and cladding layer; mainly used for high temperature resistant wire and (Note: in accordance with the skin effect theory) used as high frequency communication cable conductor.

Aluminum
Conductive silver, copper, second only to gold; good heat conductivity, good corrosion resistance, mechanical strength, good plasticity, the proportion of small. Disadvantage is the low tensile strength, which is difficult to weld. Aluminum alloy is mainly to improve the mechanical strength of aluminium, heat resistance and weldability.

Gold, nickel
Used as high temperature wire.

Iron (steel)
Often as reinforcing material composite conductor, such as aluminum over steel core wire, copper clad steel, aluminum clad steel wire etc..

Zinc
Used for steel / steel / iron conductor coatings for corrosion protection.

Tin
Used for steel / copper plating, used to prevent corrosion, and welding for copper wire.
