Resistance welding electrodes

Chromium-zirconium-copper guarantees its properties by a combination of heat treatment and cold working, so that the best mechanical and physical properties can be obtained. Resistance welding electrodes are mainly used for spot welding or seam welding of mild steel, and electrodes for coated steel plates can also be used for welding mild steel. Grip, shaft and pad material, or as electrode grip, shaft and pad material when welding mild steel, or as large dies, jigs, stainless and heat resistant steel dies or inlaid electrodes for projection welders.

EDM electrode chrome copper has good thermal conductivity, high hardness, wear resistance and anti-knock resistance, as an EDM electrode, it has good uprightness and does not bend. High finish. The electrical and thermal conductivity, hardness, wear resistance, explosion resistance, and price of the mold base material chromium copper are better than those of beryllium copper mold materials, which have been started in the mold. The industry replaced beryllium copper as the general mold material. Such as sole molds, plumbing molds, plastic molds that generally require high finish, etc. In products that require high-strength wires, such as connectors, wires, etc.

Features of chrome zirconium copper

High strength and hardness, good electrical and thermal conductivity, good wear resistance and wear reduction, after aging treatment, the hardness, strength, electrical conductivity and thermal conductivity are significantly improved, and it is easy to weld. Widely used in motor commutators, spot welders, seam welders, welding machine electrodes and other high temperature requirements for strength, hardness, conductivity and guide pad components. The production of EDM electrodes can erode the ideal mirror surface, with good erection performance, and can achieve the effects that are difficult to achieve with pure red copper such as thin sheets, and perform well on difficult-to-machine materials such as tungsten steel.
