Product Introduction

Product Introduction

  • Chromium-zirconium copper (CuCrZr)

    Chromium-zirconium copper (CuCrZr) is the most commonly used electrode material for resistance welding, which is determined by its excellent chemical and physical properties and good cost performance.

  • 1. The chromium-zirconium copper electrode has achieved a good balance of the four performance indicators of the welding electrode:

  • ☆Excellent conductivity——to ensure the minimum impedance of the welding circuit and obtain excellent welding quality ☆High-temperature mechanical properties——higher softening temperature ensures the performance and life of electrode materials in high-temperature welding environments

  • ☆Abrasion resistance——electrode is not easy to wear, prolongs life and reduces cost ☆ Higher hardness and strength - to ensure that the electrode head is not easy to deform and crush when working under a certain pressure, and ensure the welding quality

  • 2. The electrode is a kind of consumable in industrial production, and the consumption is relatively large, so its price and cost are also an important factor to consider. Compared with the excellent performance of the chromium-zirconium copper electrode, the price is relatively cheap and can meet the needs of production.

  • 3. Chromium-zirconium copper electrodes are suitable for spot welding and projection welding of carbon steel plates, stainless steel plates, coated plates and other parts. Chromium-zirconium copper materials are suitable for manufacturing electrode caps, electrode connecting rods, electrode heads, electrode grips, and special electrodes for projection welding , roll welding wheel, contact tip and other electrode parts. the

  • The standard electrode head, electrode cap, and opposite-sex electrode produced adopt cold extrusion technology and precision machining to further increase the density of the product, and the product performance is more excellent and durable, ensuring stable welding quality.

  • 2. Beryllium Copper (BeCu)

    Compared with chrome-zirconium copper, beryllium copper (BeCu) electrode material has higher hardness (up to HRB95~104), strength (up to 600~700Mpa/N/mm²) and softening temperature (up to 650°C), but its conductivity Much lower and worse.

  • Beryllium copper (BeCu) electrode material is suitable for welding plate parts with high pressure and harder materials, such as roll welding wheels for seam welding; it is also used for some electrode accessories with high strength requirements such as crank electrode connecting rods, A converter for robots; at the same time, it has good elasticity and thermal conductivity, which is very suitable for making nut welding chucks.

  • Beryllium copper (BeCu) electrodes are expensive, and we usually list them as special electrode materials.

  • 3. Copper alumina (CuAl2O3)

    Aluminum oxide copper (CuAl2O3) is also called dispersion strengthened copper. Compared with chromium-zirconium copper, it has excellent high-temperature mechanical properties (softening temperature up to 900 ° C), higher strength (up to 460~580Mpa/N/mm²) , and good conductivity (conductivity 80~85IACS%), excellent wear resistance, long life.

  • Aluminum oxide copper (CuAl2O3) is an electrode material with excellent performance, regardless of its strength and softening temperature, it has excellent electrical conductivity, especially for welding galvanized sheets (electrolytic sheets), it will not be like Chromium-zirconium-copper electrodes have the phenomenon of sticking between the electrode and the workpiece, so there is no need for frequent grinding, which effectively solves the problem of welding galvanized sheets, improves efficiency, and reduces production costs.

  • Alumina-copper electrodes have excellent welding performance, but their current cost is very expensive, so they cannot be widely used at present. Due to the wide application of galvanized sheet at present, the excellent performance of aluminum oxide copper welding to galvanized sheet makes its market prospect broad. Alumina copper electrodes are suitable for welding parts such as galvanized sheets, hot-formed steels, high-strength steels, aluminum products, high-carbon steel sheets, and stainless steel sheets.

  • 4. tungsten (W), molybdenum (Mo)

    Tungsten electrode (Tungsten) Tungsten electrode materials include pure tungsten, tungsten-based high-density alloy and tungsten-copper alloy. ) containing 10-40% (by weight) of copper. Molybdenum electrode (Molybdenum)

  • Tungsten and molybdenum electrodes have the characteristics of high hardness, high burning point, and excellent high-temperature performance. They are suitable for welding non-ferrous metals such as copper, aluminum, and nickel, such as the welding of copper braids and metal sheets of switches, and silver point brazing.
