Product Description

RWMA Class 12 Copper tungsten

Elkonite 30W3 & Elkonite 3W53 welding copper alloy


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.


RWMA Class 12
Elkonite 30W3 & Elkonite TC10
Elkonite® 30W3 Tungsten-Copper and Elkonite® TC10 Tungsten Carbide-Copper alloys are recommended for volume projection welding dies where the pressures involved are relatively high. Electrical upsetting of non-ferrous metals and low carbon steel is usually accomplished by the use of such Elkonite® materials as die facings. Cross-wire welding of large diameter wire and rod is accomplished with such Elkonite® materials.


Elkonite 3W53 & Elkonite 10W53
Elkonite® 3W53 and Elkonite® 10W53 are heat treatable grades of Elkonite® Tungsten-Copper materials supplied in the fully heat treated condition. If silver brazed to a die backing, such Elkonite® materials should be heat treated after brazing. These harder grades are used primarily for electroforging and electrical upsetting dies, where temperatures and pressures are comparatively high.


Elkonite TC20 & Elkonite TC53
Elkonite® TC20 and Elkonite® TC53 are Tungsten Carbide-Copper materials and are extremely hard and wear resistance. Elkonite® TC20 material, while somewhat difficult to machine, may be machined using carbide tipped tools. Elkonite® TC53 material is a heat treatable grade of such high hardness that machining operations are impractical and the material must be ground. Such Elkonite® materials are customarily used for special applications of electrical upsetting and electroforging.
