Common electrode materials

Electrode materials are divided into 4 categories according to the regulations of the Aviation Industry Standard HB5420-89 of the Ministry of Aerospace Industry of my country, but the first three categories are commonly used.

1 . copper and copper alloys with high conductivity and medium hardness. This type of material mainly achieves its hardness requirements through cold work deformation methods. It is suitable for making electrodes for welding aluminum and aluminum alloys, and also for spot welding of coated steel plates, but its performance is not as good as that of Class 2 alloys. Type 1 alloys are also commonly used to make non-stressed or low-stress conductive parts.

2. has higher conductivity and higher hardness than Type 1 alloys. This type of alloy can meet its performance requirements through a combination of cold work deformation and heat treatment. Compared with Class 1 alloys, it has higher mechanical properties, moderate electrical conductivity, and strong resistance to deformation under moderate pressure.

3. Alloys with conductivity lower than Type 1 and Type 2, and hardness higher than Type 2. This type of composite can meet its performance requirements through heat treatment or a combination of cold work deformation and heat treatment. This type of alloy has higher mechanical properties and good wear resistance, high softening temperature, but low conductivity per ton.
