What is Elkonite?
Our Tungsten Copper Elkonite® alloys are commonly used in electrical & electrical/thermal applications. They are used for facing and inserts for flash and butt welding dies, projection welding electrodes, seam welding bearing inserts, facing for electro-forming & electro-forging dies, and EDM electrodes.

Although they are somewhat more difficult to machine, Tungsten Carbide Copper materials (TC materials) provide high mechanical properties and excellent resistance to erosion. They are commonly used in oil devices to protect the contact from oxidation.

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 and 3W3 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 for spot welding (as a radius faced electrode) low conductivity ferrous metals such as stainless steel.
ELKONITE® 5W3 and TC5 alloys are normally used for light duty projection welding dies where welding pressures are not extreme.

ELKONITE® 10W3 alloy is used for electrode and die inserts in most flash and butt welding dies and for projection welding dies where welding pressures are moderate. It is also used for light electrical upsetting, electroforging dies and seam welder bushing inserts.

ELKONITE® 30W3 and TC10 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 weld- ing of large, diameter wire and rod is accomplished with such ELKONITE® materials.

ELKONITE® 3W53 and 10W53 are heat treatable grades of ELKONITE® materials supplied in the fully heat treated con- dition. 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 com- paratively high.
