Main raw materials of wire and cable in the field of security monitoring

Updated: Jul 23

Wire and cable materials in the field of security monitoring can be divided into conductive materials, insulating materials, sheathing materials, shielding materials, filling materials, etc. according to their use parts and functions.


According to the material properties, it can be divided into metals (copper, aluminum, aluminum alloy, steel), plastics (PVC, PE, PP, XLPE / XL-PVC, PU, TPE / PO), rubber, etc. But some of these materials are common to several structural parts.


Especially thermoplastic materials, such as polyvinyl chloride, polyethylene, etc., can be used on insulation or jackets as long as part of the formulation composition is changed.




Hangzhou Zion Communication will introduce the commonly used non-metallic wire and cable raw materials for everyone:

Metal raw materials
  • Copper: conductivity is second only to silver, thermal conductivity is second only to gold and silver; corrosion resistance, non-magnetic, good plasticity, easy to weld, and wide range of uses. Copper alloy is mainly used to improve the wear resistance, corrosion resistance, and mechanical physical properties of copper.

  • Silver: The metal has high electrical and thermal conductivity, has good corrosion resistance and oxidation resistance, and is easy to weld; it is mainly used for plating and cladding; it is mainly used for high-temperature resistance and (note: according to the principle of skin effect) Be a high-frequency communication cable conductor.

  • Aluminum: conductivity is second only to silver, copper, and gold; good thermal conductivity, good corrosion resistance, general mechanical strength, good plasticity, and low specific gravity. The disadvantage is that the tensile strength is low and it is not easy to weld. Aluminum alloy is mainly used to improve the mechanical strength, heat resistance, and weldability of aluminum.

  • Gold, nickel: used as high-temperature wire.

  • Iron (steel): often used as a reinforcement material for composite conductors, such as steel core aluminum wire, copper-clad steel, aluminum-clad steel wire, etc.

  • Zinc: used as a coating for steel wire/steel strip/iron conductor to prevent corrosion.

  • Tin: used as a coating for steel wire/copper wire to prevent corrosion and facilitate copper wire welding.
