By developing a melting technology that adds Zr to Cu-Cr for the first time in Korea, we have achieved quality stabilization that maintains the characteristics of the Cu-Cr-Zr material consistently. Our Cap-Tip has a high softening temperature, high temperature hardness, and high strength. , Zinc corrosion resistance has been improved due to the formation of Cu·Cr·Zr and Cu·Zr precipitates, thereby significantly reducing the sticking phenomenon when welding not only cold rolled steel sheets but also galvanized steel sheets, and the weld life is much longer than that of existing products. It got longer.
