广东11选5Why choose this company produces a new type of resistance welding electrode?
广东11选5New auto assembly lines with resistance welding electrode to the Company's independent development of dispersion-strengthened copper alloy for the raw materials. With the use of advanced oxidation processes and precision forming process, so that the alloy in the copper-based body in the introduction of nano-scale distribution of small Al2O3 particle dispersion, thus ensuring that the electrode in copper-based body to maintain excellent electrical conductivity, thermal conductivity at the same time, with a high The room-temperature strength and high temperature strength.
1. New automobile assembly line with the characteristics of resistance welding electrode
1. Superior high temperature strength and hardness (softening temperature ≧ 900 ℃)
Resistance welding electrodes at work have to bear the high temperature and high pressure of the combined effects, and direct contact with the electrode face temperature solder joint surface, poor working conditions. Using the traditional Cu-Cr alloy and Cu-Cr-Zr alloy resistance welding electrodes, high temperature strength due to low softening temperature low at high temperature and pressure under deformation and adhesion prone to failure and damage and so on. The use of diffusion of copper production a new type of resistance welding electrodes to ensure excellent conductivity electrode, thermal performance with high temperature strength and hardness, resulting in improved electrode life.
I produced by resistance welding electrode properties of dispersion-strengthened copper alloy with chromium electrodes with the traditional bronze and Cu-Cr-Zr alloy performance comparison is shown in Table 1, Figure 1 and Figure 2.
