Spot Welding Copper Rod

Spot welding copper rod is the core electrode material for resistance spot welding equipment, widely used in battery assembly, automotive manufacturing, home appliances, and hardware industries. Manufactured from high-quality copper alloys, this product achieves an excellent balance between electrical conductivity, thermal conductivity, high-temperature softening resistance, and wear resistance, ensuring strong weld points, consistent quality, and extended electrode service life.

High Electrical Conductivity: 80-94% IACS, minimizing energy loss and concentrating heat at the weld zone

High-Temperature Softening Resistance: Alumina copper softening point at 930℃, CrZr copper ≥550℃, maintaining hardness under high-temperature conditions

Extended Service Life: Electrode life more than 5 times that of ordinary chromium-zirconium copper, reducing downtime for dressing

Non-Sticking Electrode: No adhesion when welding coated metals such as galvanized or nickel-plated sheets; clean, yellowing-free weld joints

Stable Weld Quality: Eliminates false welds and reduces welding spatter

Environmental Certified: Passed EU ROHS environmental certification standards

Lithium Battery Assembly: Spot welding connections for nickel strips, nickel-plated steel strips, and coated strips

Automotive Manufacturing: Resistance spot welding of body panels, chassis, and components

Appliance Manufacturing: Welding of refrigerator, air conditioner, and washing machine housings

Hardware Products: Spot welding of stainless steel, brass, and other metals

Electronics Industry: Switch contacts, conductive nozzles, and other conductive components
