The differences between beryllium nickel copper and chromium zirconium copper in welding

1. It also has the property of withstanding high temperatures up to 500 degrees, and has good conductivity.

2. beryllium nickel copper is harder than chromium zirconium copper, so beryllium nickel copper outperforms chromium zirconium copper in terms of wear resistance and usability.

3. Machinability - beryllium nickel copper compared to chromium zirconium copper

4. The new beryllium nickel copper has a higher conductivity than chromium zirconium copper.

5. The densities of the two materials are different - for high photoelectric sparks in molds, chromium zirconium copper is the preferred choice.Chromium zirconium copper has high strength and hardness, good electrical conductivity and thermal conductivity, excellent wear resistance and anti-wear properties. After aging treatment, its hardness, strength, electrical conductivity and thermal conductivity all significantly increase, and it is easy to weld. It is widely used in motor rectifiers, spot welders, seam welders, butt welders, electrodes for other parts requiring high temperature strength, hardness, electrical conductivity and thermal conductivity. When used to make electro-discharge electrodes, it can produce a relatively ideal mirror surface, and has good rigidity. It can achieve effects that pure red copper cannot reach, such as thinning sheets, and performs well on difficult-to-machine materials like tungsten steel.

Beryllium copper alloy possesses excellent comprehensive properties such as high strength, high conductivity, high elasticity, fatigue resistance, wear resistance, cold resistance, non-magnetism and no sparking during impact. It is an indispensable important structural and functional material in national economic construction and national defense and military industry construction. It is mainly applied in fuses, fasteners, springs, switch components, electrical connectors, wires, resistance welding electrode heads, seam welding electrode discs, mold casting plug head, plastic molds, automotive industry, etc.

What welding scenarios can beryllium nickel copper be used for?

Beryllium-nickel-copper is commonly used in spot welding and seam welding scenarios. In spot welding, it is often used as the electrode for spot welding stainless steel and heat-resistant steel, the grip rod for the force-bearing electrode, shafts and electrode arms. When welding these materials, due to its ability to maintain high strength at high temperatures, it can meet the requirements for higher electrode strength and can also perform well when higher electrode pressure is required. In seam welding, it can be made into the electrode shaft and bushings for seam welding stainless steel and heat-resistant steel. In addition, when welding some special materials that require high precision and high-quality welding, beryllium nickel copper can ensure welding quality and the strength and stability of the welding joint by virtue of its excellent properties.
