Chromium zirconium copper (CuCrZr) chemical composition (mass fraction) % (Cr: 0.1-0.8, Zr: 0.3-0.6) hardness (HRB78-83) conductivity 43ms/m
Chromium zirconium copper has good electrical conductivity, thermal conductivity, high hardness, wear resistance, explosion resistance, crack resistance and high softening temperature, less electrode loss during welding, fast welding speed, and low total welding cost. It is suitable as an electrode for fusion welding machines. For pipe fittings, and other parts that require strength, hardness, conductivity, and pad properties at high temperatures. The electric spark electrode can be used to etch an ideal mirror surface, and at the same time, it has good upright performance, and can achieve the effects that are difficult to achieve with pure red copper such as thin slices. It performs well on difficult-to-machine materials such as tungsten steel.

This product is widely used in various materials for welding, contact tips, switch contacts, mold blocks, and auxiliary devices for welding machines in the machinery manufacturing industries such as automobiles, motorcycles, and barrels (cans).
The specifications of bars and plates are complete and can be customized according to customer requirements.
performance
1. The eddy current conductivity meter is used for conductivity measurement, and the average value of three points is ≥44MS/M
2. The hardness is based on Rockwell hardness standard, take the average of three points ≥78HRB
3. Softening temperature test, after the furnace temperature is kept at 550 °C for two hours, the hardness cannot be reduced by more than 15% compared with the original hardness after quenching water cooling
Hardness: >75HRB, Conductivity: >75%IACS, Softening Temperature: 550℃
Resistance welding electrodes
Chromium-zirconium-copper guarantees performance by combining heat treatment with cold working. It can obtain the best mechanical properties and physical properties, so it is used as a general-purpose resistance welding electrode, mainly used for spot welding or seam welding of low carbon steel, coating Electrodes for steel plates can also be used as electrodes, grips, shafts and gasket materials for welding mild steel, or as large molds, fixtures, molds for stainless steel and heat-resistant steel, or inlaid electrodes for projection welders.
spark electrode
Chromium zirconium copper has good electrical and thermal conductivity, high hardness, wear resistance and explosion resistance. It has the advantages of good uprightness, no bending of thin slices, and high finish when used as an EDM electrode.
Mold base material
Chromium copper has the characteristics of electrical and thermal conductivity, hardness, wear resistance and explosion resistance, and its price is superior to that of beryllium copper mold materials. It has begun to replace beryllium copper as a general mold material in the mold industry. For example, shoe sole molds, plumbing molds, plastic molds that generally require high cleanliness, and other connectors, guide wires, and other products that require high-strength wires.
How does chrome zirconium copper turn black?
Chromium zirconium copper is prone to oxidation after processing, so pay attention to rust protection in time after processing.
