The commonly used conductor materials for wire pogopin are: copper-clad steel wire, copper-clad aluminum wire, bare copper wire, tinned copper wire, and silver-plated copper wire. However, due to the high performance requirements of high-temperature wires, the commonly used conductor materials for high-temperature wires are tinned copper wire and silver-plated copper wire. Dongguan Qinda high temperature resistant wire manufacturer explains the definition of tinned copper wire and silver-plated copper wire for everyone.
One of the commonly used conductor materials for high temperature wires: tinned copper wire, which means that metal tin is plated on the surface of the copper conductor by hot-dip or electroplating to prevent copper corrosion, discoloration and make the conductor easier to weld; it is divided into single (or solid) ) tinned copper wire and twisted; the purpose of twisting is to keep the conductors soft.
The second commonly used conductor material for high-temperature pogopin wires: silver-plated copper wire, which mainly increases the conductivity of the conductor (better than bare copper wire), good oxidation resistance and heat resistance, and is processed in the same way as tin-plated copper wire. (or solid) silver plated copper wire and twisting; the purpose of twisting is to keep the conductors soft.
In addition, there are also some high-temperature wires that use bare copper wire as conductor material, because bare copper wire has high conductivity, but it is easy to oxidize at high temperature; it is divided into single (or solid) bare copper wire and stranded bare copper wire; stranded The purpose is to keep the conductors soft.
The metal materials used in wire conductors are mainly silver, copper, aluminum, gold, nickel, iron (steel), zinc and tin. What are the characteristics of each metal material? The following is the answer from Dongguan Qinda high temperature line.
1. Silver, metal has the highest electrical conductivity and thermal conductivity, has excellent corrosion resistance and oxidation resistance, has excellent plasticity, and is easy to weld. It is mainly used for high temperature resistant wires (based on the skin effect principle) and high-frequency communication cable conductors coating and cladding;
2. Copper, the electrical conductivity is second only to silver, the thermal conductivity is second only to gold and silver, corrosion resistance, non-magnetic, good plasticity, easy to weld, and widely used. The main purpose of copper alloy is to improve the wear resistance, corrosion resistance and mechanical and physical properties of copper.
3. Aluminum is second only to silver, copper and gold in electrical conductivity, with good thermal conductivity and corrosion resistance, normal 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 alloy is mainly to improve the heat resistance, weldability and mechanical strength of aluminum.
4. Gold and nickel are used as high temperature resistant wires.
5. Iron (steel) is often used as a reinforcing material for composite conductors, such as steel-cored aluminum stranded wire, copper-clad steel, aluminum-clad steel wire, etc.
6. Zinc is used as a coating for steel wires, steel strips and iron conductors to prevent corrosion.
7. Tin is used as a coating for steel wires and copper wires, which has an anti-corrosion effect and is beneficial to the welding of copper wires.
