The Difference Between CuCr (Chromium Copper) and CuCrZr (cChromium Zirconium Copper)

Common ground: They are all copper alloy materials, suitable for use as resistance welding electrodes, with high hardness and strength; It has the characteristic of high-temperature softening and can resist high temperatures while maintaining its chemical and physical properties at a temperature of approximately 450 ℃ to 550 ℃; Having a certain degree of wear resistance and a longer service life; Has good conductivity.

Differences: In copper alloy smelting, CuCr only adds Cr element to copper; And CuCrZr, in addition to adding a certain amount of Cr element, also adds Zr element, which has wear resistance, toughness and other characteristics. Therefore, compared with CuCr, CuCrZr has better wear resistance, longer service life, and also increases the high-temperature softening temperature. Therefore, CuCrZr has more advantages as an electrode material.

BeCu

Compared with chromium zirconium copper, beryllium copper (BeCu) electrode material has higher hardness (up to HRB95-104), strength (up to 800Mpa/N/mm2), and softening temperature (up to 650 ℃), but its conductivity is much lower and poorer. Beryllium copper (BeCu) electrode material is suitable for welding plate parts with high pressure, as well as harder materials such as roller welding wheels used for welding seams; It is also used for electrode accessories with high strength requirements, such as crank electrode links, and converters for robots; At the same time, it has good elasticity and thermal conductivity, and is very suitable for manufacturing stud welding chucks. Beryllium copper (BeCu) electrode has a high cost and is usually classified as a special electrode material.
