Hardness of Chromium Zirconium Copper Heat Treated

Chromium zirconium copper (CuCrZr) chemical composition (mass fraction)% (Cr: 0.1-0.8, Zr: 0.3-0.6) Hardness (HRB78-83) Electrical conductivity 43ms/m Softening temperature 550℃

Features
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, but for electroplated workpieces, the performance is average.

application
This product is widely used in various materials for welding, contact tips, switch contacts, mold blocks, and welding machine auxiliary devices in the machinery manufacturing industries such as automobiles, motorcycles, and barrels (cans).

Specification
The specifications of bars and plates are complete and can be customized according to customer requirements.

Quality requirements
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

physical index
Hardness: >75HRB, Conductivity: >75%IACS, Softening Temperature: 550℃

Resistance welding electrodes
Chromium zirconium copper guarantees performance by a combination of heat treatment and cold working, it can obtain better mechanical properties and physical properties, so it is used for
It is a general-purpose resistance welding electrode, mainly used as an electrode for spot welding or seam welding of low carbon steel and coated steel plate, and can also be used as an electrode when welding low carbon steel.
Grip, shaft and spacer material, or as electrode grip, shaft and spacer material when welding mild steel, or as large die, jig,
Die or inlay electrodes for stainless steel and heat-resistant steel.

spark electrode
Chromium copper has good electrical and thermal conductivity, high hardness, wear resistance and explosion resistance.
The advantages of high curvature and smoothness.

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 a high degree of wire.
