Our chrome-zirconium-copper sheets and bars are precision-forged, rolled, free of sand holes and pores, with even hardness and fine structure.

This product boasts excellent electrical and thermal conductivity, crack resistance, high hardness, wear and impact resistance, high softening temperature, minimal electrode wear during welding, and fast welding speed with low costs. It is suitable for motor-related fittings in fusion welding machines, although its performance for electroplated workpieces is average. When used as an electrospark electrode, it can produce a highly reflective surface and has good vertical performance, enabling effects that pure red copper cannot achieve, such as thin sheet formation. It also performs well on difficult-to-machine materials like tungsten steel. It can serve as electrode screws, electrode wheels, shafts, and gaskets for spot welding or seam welding of low-carbon steel and coated steel plates, or as large molds, fixtures, and inlay electrodes for resistance welding machines. Due to its lower price compared to beryllium copper, chrome-zirconium copper material is beginning to replace beryllium copper as a general mold material in the mold industry, such as for shoe sole molds and plumbing fixtures. It is also suitable for products requiring high surface finish, such as plastic molds, connectors, wire guides, and items requiring high-strength conductors.

This product is now widely used in the welding, electrical nozzles, switch contacts, mold blocks, and auxiliary equipment for welding machines in industries such as automotive, motorcycle, barrel-making, can-making, and mechanical manufacturing.

Our products undergo strict conductivity tests and flaw detection before being sold, ensuring their quality and safety. Please rest assured in their use.
