Resistance Welding Electrodes

Oxygen free copper (OFHC)

Oxygen free copper (OFHC)

Taking an account in the name, Oxygen free copper (OFHC) is regarded as Oxygen free high thermal conductivity copper. Therefore, it is popular as copper alloy having high conductivity and is electrolytically refined for decreasing the amount of oxygen to .001% or below it. Relying on its chemical property, this copper is widely used in plasma deposition processes, manufacturing of semiconductor and components of superconductor.

Seam Wheels

Seam Wheels

Engineered to eliminate common failure of wheels, these Seam Wheels show high conductivity when come in contact with any surface. The optimum structure of the present range is best for maximizing the yield and offer proper hardness while upholding the necessary ductility. Setting a benchmark in the current industry, these wheels are designed for conducting welding current to work, transmitting the pressure on electrode to work in producing a satisfactory welding functioning and not the least used for dissipating heat from weld zone.

Composition CuCrZr, CuCr1Zr
Hardness (HRB) ≥75
Conductivity % (IACS) ≥85
Forms available Diameter
Available upon request
Features :
  • Deformation resistant
  • Corrosion free
  • High electrical conductivity
