Chromium zirconium niobium copper has higher conductivity and hardness than that of class 1 alloy. This kind of alloy can be obtained by cold deformation and heat treatment. Compared with type 1 alloy, it has high mechanical properties, moderate conductivity, in the medium degree of pressure, has a strong resistance to deformation, so it is a general electrode material, widely used for spot welding of low carbon steel, low alloy steel, stainless steel, high temperature alloy, low conductivity of copper alloy, and coated steel. Type 2 alloy is also suitable for manufacturing various conductive parts in resistance welder such as shaft, clamp, plate, electrode chuck, machine arm, etc.
Class 1 - high conductivity, medium hardness copper and copper alloys. This kind of material mainly achieves its hardness by cold deformation method. It is suitable for making electrodes for welding aluminum and aluminum alloys, and can also be used for spot welding of coated steel plates, but its performance is not as good as that of class 2 alloys. Class 1 alloys are also commonly used to make conductive parts with no or low stress.
The main functions of chromium zirconium niobium copper are: 1. 2. Transfer pressure to the workpiece; 3. Rapidly dissipate heat in the welding area.
