Achieve Precision and Performance with Copper Tungsten Alloys

Copper tungsten alloys are a unique composite material that combines the benefits of both copper and tungsten to create an exceptional balance of thermal and electrical conductivity and high strength and durability. From class 10 to class 14, these alloys are tailored to meet specific requirements for various industrial and technological applications. Each class differs in the proportion of copper and tungsten, allowing for fine-tuned properties that cater to the needs of industries such as aerospace, electronics, and automotive.

Class 10

30% COPPER | 70% TUNGSTEN

Light duty projection welding dies where weld pressures are medium to light.

Class 11

25% COPPER | 75% TUNGSTEN

Used for facings and inserts for flash and butt welding dies, projection welding electrodes, seam welding, bearing inserts, facings for electroforming, and electro-forging dies. Often used for EDM electrodes for greater wear ratios.

Class 12

20% COPPER | 80% TUNGSTEN

Heavy-duty projection welding electrodes die facings for electro-forming and electro-forging, also facings for upsetting rivets and studs.

Class 13

100% TUNGSTEN

Recommended principally for welding or electro-brazing non-ferrous metals having relatively high electrical conductivity. Cross-wire welding or copper and brass wires and welding of copper wire braid to brass and bronze terminals are typical applications. Generally, special set-ups and procedures are required for this type of work.

Class 14

100% MOLYBDENUM
