Tungsten Copper Class 10 (1W3, 5W3)

Class 10 material is recommended as facings or inserts for projection welding electrodes and flash and butt welding dies where high electrical conductivity is desirable and a degree of malleability is necessary.

Tungsten Copper Class 11 (10W3)

Class 11 (a harder material than Class 10) is recommended as facing inserts for flash and butt welding dies and general purpose projection welding electrodes.? It may also be used as seam welder bearing inserts and facing for electro-forming or electro-forging, such as stainless steel.

Tungsten Copper Class 12 (30W3)

Class 12 material is specifically recommended for heavy duty projection welding electrodes and for die facings in electro-forming and electro-forging applications.? It is suitable as die material for electrical upsetting of rivets and studs.

Tungsten Copper from Chinatungsten owns the advantages as follows:
Highest thermal conductivity available for this material system
Isotropic thermal and mechanical properties
Tailored thermal expansions
Requires no expensive tooling
High precision components machined to customer print
Plating and metallization options available
Hermetic

Chinatungsten’s manufacturing process begins with high purity tungsten powder that is compacted and sintered without adding lubricants, binders, or sintering aides. Sintered tungsten parts are then infiltrated with Oxygen Free High Conductivity (OFHC) copper yielding a composite material with exceptional engineering properties. Our high purity sinter & infiltrate process produces a composite material with superior thermal conductivity, stability, and tailored thermal expansion.
