Commonly used conductor materials for wires are: copper-clad steel wire, copper-clad aluminum wire, bare copper wire, tin-plated 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 tin-plated copper wires and silver-plated copper wires.
One of the commonly used conductor materials for high-temperature wires: Tin-plated copper wire refers to metal tin plated on the surface of copper conductors by hot plating or electroplating to prevent copper corrosion, discoloration, and make conductors easier to solder; divided into single (or solid) ) Tinned copper wire and stranding; the purpose of the stranding is to keep the conductor soft.
High-temperature wire commonly used conductor material 2: silver-plated copper wire, mainly to increase the conductive properties of the conductor (better than bare copper wire), good oxidation resistance and heat resistance, the same processing method as tin-plated copper wire, divided into single ( Or solid) silver-plated copper wire and stranding; the purpose of the stranding is to keep the conductor soft.
In addition, some high-temperature wires use bare copper wires as the conductor material, because bare copper wires have high conductivity but are susceptible to oxidation at high temperatures; divided into single (or solid) bare copper wires and twisted bare copper wires; twisted The purpose is to keep the conductors soft.
