Dispersion strengthened copper resistance welding electrodes advantages 
 Dispersion strengthened copper can be processed into various types of resistance welding electrode, electrode cap, electrode, electrode arm, seam welding wheels, and can be used for coating plates, carbon steel, alloy steel, aluminum, copper, dissimilar materials, as well as ranging from slab spot welding, seam welding, butt. Diffusion of copper electrode has a very good high temperature strength, excellent high-temperature electrical conductivity, high temperature thermal conductivity, excellent resistance to softening at high temperatures, and also has good ductility and machining performance. Compared with the traditional electrode materials chromium zirconium copper, beryllium, cobalt and copper diffusion of copper electrode material has the following advantages: 
 (1) long life, long prepared by the material, spot welding electrode life, reduce downtime, repair, replacement, welding efficiency greatly improved. 
 (2) the quality of welding, soldering, adhesive electrode phenomenon, without sealing off the phenomenon. 
 (3) a good working environment, small welding sparks or welding sparks appear when welding. 
 4 solder joint appearance, the welded joints of yellow, there is no spot imprinted, without subsequent polishing, improve production efficiency and reduce costs. 
 Dispersion strengthened copper main performance parameters: 
 Density (g/cm3) Hardness (HRB) conductivity (IACS%) softening temperature (° C) extension rate (%) tensile strength (MPa) 
 > 8.87 75-85 78-85 900 8-12 450-530 
 Chromium zirconium copper main performance parameters: 
 Density (g/cm3) Hardness (HRB) conductivity (IACS%) softening temperature (° C) extension rate (%) tensile strength (MPa) 
 > 8.89 75-83 75-85 500-550 ≥ 15 ≥ 380 
 Diffusion of copper chromium zirconium copper biggest advantage is the softening temperature is high, because the electrode products are used in high temperature, so when the electrode temperature reaches 550 ° C, above, chromium zirconium copper has softened failure, hardness and conductivity of a sharp decline in can not continue to use, conduction and diffusion of copper products can still continue to use at a higher temperature range 550-900 ° C, maintaining its high hardness, high electrical conductivity performance, thereby increasing the life of.
