Chromium zirconium copper chemical composition (mass fraction) % (Cr: 0.1-0.8, Zr: 0.1-0.6) hardness (HRB78-83) conductivity 43ms/m
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 for use as an electrode for fusion welding machines. For pipe fittings, but for electroplated workpieces, the performance is average.
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 its performance by a combination of heat treatment and cold working. It can obtain the best 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 electrode grip, shaft and gasket material when welding low carbon steel, or as an electrode when welding low carbon steel. Electrode grips, shafts and gasket materials, or as large molds for projection welders, fixtures, molds for stainless and heat-resistant steel, or inlaid electrodes.
spark electrode
Chromium-copper has good electrical and thermal conductivity, high hardness, wear resistance and anti-explosion. It has the advantages of good uprightness, no bending 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, etc. connectors, guide wires, and other products that require high-strength wires.
