Metal material for cable


The metal materials for cables mainly include: silver, copper, aluminum, gold, nickel, iron (steel), zinc and tin.

1. Silver, metal has the highest conductivity and thermal conductivity, has good corrosion resistance and oxidation resistance, has good plasticity, is easy to weld, and is mainly used for high temperature resistant wire (according to the principle of skin effect) and high frequency communication cable conductor Plating and cladding;


2. Copper is second only to silver in electrical conductivity. Its thermal conductivity is second only to gold and silver. It is corrosion-resistant, non-magnetic, plastic, easy to weld and has a wide range of uses. Copper alloys mainly improve the wear resistance, corrosion resistance, and mechanical and physical properties of copper.


3. Aluminum, conductivity is second only to silver, copper and gold. It has good thermal conductivity and corrosion resistance, general mechanical strength, good plasticity and small specific gravity. The disadvantage is that the tensile strength is low and it is not easy to weld. Aluminum alloys mainly improve the heat resistance, weldability and mechanical strength of aluminum.


4. Gold and nickel are used as high temperature resistant wires.
