| Chromium zirconium copper chemical composition (mass fraction)% (Cr: 0.1-0.8, Zr: 0.1-0.6) hardness (hrb78-83) conductivity 43ms / M
characteristic
Chromium zirconium copper has good 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 for electrode related pipe fittings of fusion welding machine, but it is generally good for electroplated workpiece.
Specifications
Bar and plate specifications are complete, and can be customized according to customer requirements.
quality requirement
1. 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, and the average value of three points is = 78hrb
3. Softening temperature test: after the furnace temperature is maintained at 550 ? for two hours, the hardness can not 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 electrode
Chromium zirconium copper can obtain the best mechanical and physical properties through the combination of overheating treatment and cold working
As a general-purpose resistance welding electrode, it is mainly used as an electrode for spot welding or seam welding of low carbon steel and coated steel plate, and also as an electrode for welding low carbon steel
Grip rod, shaft and pad materials, or as electrode grip rod, shaft and pad materials when welding low carbon steel, or as large molds, fixtures and
