Our chrome-zirconium-copper sheets and bars are precision-forged under high pressure, with rolled surfaces free of sand holes and blow holes, even hardness, and fine texture.
This product boasts excellent electrical and thermal conductivity, resistance to cracking, high hardness, wear and impact resistance, and high softening temperature. It features minimal electrode wear during welding, with fast speed and low cost, making it suitable for motor-related components in melting welding machines. However, its performance with electroplated workpieces is average. As an electrode for electrical discharge machining, it can produce a highly reflective surface, has good verticality, and can achieve effects that pure red copper cannot, such as thin sheet processing, and performs well on difficult-to-machine materials like tungsten steel. It can also serve as electrodes, worms, wheels, shafts, and shims 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 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-conductivity wires.
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 mechanical manufacturing industries.
Our products undergo rigorous conductivity tests and flaw detection with an ultrasonic flaw detector before being sold, ensuring their quality before delivery. Customers can use them with confidence.
