Why Our Electrodes Stand Out?
- Seamless NDB Bonding: Copper and refractory metals like tungsten and molybdenum are bonded without seams or defects, achieving a connection strength of >130 MPa.
- High Precision: Tip accuracy down to 0.05 µm ensures reliable welds on delicate components.
- Durable & Versatile Materials:
- Tungsten and molybdenum tips: Withstand extreme temperatures, maintain shape, and prevent deformation.
- Copper bases (chromium zirconium copper or oxygen-free copper): Enhance heat conductivity and durability.
- Advanced Densification Process: Electrodes feature a high-density, uniform internal structure, reducing risks of cracks or defects.
- Customizable Solutions: Tailor-made designs to suit specific welding requirements and material types.
- Wide Material Compatibility: Ideal for tungsten, molybdenum, stainless steel, and alloys like Inconel and nichrome.

Our tungsten and molybdenum resistance welding electrodes are now used in the automobile industry
manufacturing of famous automobile brands, such as GM, Toyota.
A leading auto parts manufacturer, purchasing our lanthanated tungsten (WL20) back cast Cu electrode instead of used tungsten copper electrode before, incresing the work shots from 500 to 50000 greatly. As we know, they buy the electrode to weld the copper and copper alloy sheet to the lead wire in auto motors processing. After the evaluation, our engineer gave the professional advice and improved the electrode work life, saving much cost.
