Product Description

RWMA Class 10 Copper tungsten

Electrodes Resistance Welding Copper Alloys


Resistance Welding is the coordinated application of electric current and mechanical pressure in the proper magnitudes and for a precise period of time to create a coalescent bond between two base metals. Weld electrodes are used to conduct the electric current to the base metals as they are forged together.

Resistance Welding Products: Adaptors, Bushings, Electrodes (straight, single and double bend, back up, nut and stud, threaded, refractory faced and swivel head electrodes), Dies & Fixtures, Electrode Holders (cylinder-mounted multi-spot, straight welding electrode, ejector and non-ejector, offset, platen mounted and fast-follow-up holders), Flash & Butt Welding Dies, Holders, Pneumatic Cylinders, Resistance Welding Electrodes, Seam Welding Wheels, Shafts, Shanks, Spot Welding Electrodes, Spot Welding Caps, Transformers, Welding Arms, Welding controls, Welding Connectors, Welding Platens, Welding wheels & Blanks.


  • Description

JINXING MATECH adopts isostatic pressing-high temperature sintering tungsten skeleton-copper infiltration process to produce various large and special-shaped parts with a copper content of 6-90%. The product has high purity, uniform structure and excellent performance. It can produce various sheets, rods, pipes, plates and small-sized products with complex shapes by compression molding, extrusion molding, and injection molding.

Elkonite 1W3 & Elkonite 3W3

Elkonite® 1W3 and Elkonite® 3W3 Tungsten-Copper alloys are generally used for flash and butt welding die inserts where higher electrical and thermal conductivity is necessary and where a degree of malleability is desirable. These materials are also used (as a radius faced electrode) for spot welding low conductivity ferrous metals such as stainless steel.


Elkonite 5W3 & Elkonite TC4

Elkonite® 5W3 Tungsten-Copper and Elkonite® TC5 Tungsten Carbide-Copper alloys are normally used for light duty projection welding dies where welding pressured are not extreme.
