Our chrome-zirconium-copper sheets and bars have been precision forged under high pressure, cold rolled, free from sand holes and pores, with uniform hardness and fine texture.

This product boasts excellent conductivity, thermal conductivity, crack resistance, high hardness, wear and impact resistance, high softening temperature, and minimal electrode loss during welding, resulting in faster welding speeds and lower costs. It is suitable for motor-related components in fusion welding machines but performs averagely on electroplated workpieces. As an electrode for electrospark erosion, it can produce a highly reflective finish and has good upright performance, enabling effects that pure red copper cannot achieve, such as thin sheet making. It also performs well on difficult-to-machine materials like tungsten steel. Additionally, it can be used as electrodes, electrode screws, wheels, shafts, and pads for spot or seam welding 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, chromium-zirconium copper material is beginning to replace beryllium copper as a general mold material in industries such as shoe sole molds and plumbing fixtures. It is also suitable for products requiring high surface finish, such as plastic molds, connectors, wire guides, and products requiring high-strength conductors.

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

Our products undergo rigorous conductivity tests and flaw detection inspections before being sold, ensuring their quality before delivery. Customers can rest assured in their use.
