Elkonite® available from Weld Systems Integrators

Tungsten Copper Elkonite® available from Weld Systems Integrators is commonly used in electrical and electrical / thermal applications.

Elkonite, often More difficult to machine, TC materials provide high mechanical properties and excellent erosion resistance. Call us at 844-WSI-WELD to learn more.

Elkonite is the registered trade mark of Tuffaloy (formerly CMW) used to identify a group of metal compositions whose elements consist basically of the refractory metals tungsten, molybdenum and tungsten carbide combined with copper. Combinations of these elements produce dense, hard metals of superior wear resistance and strength at elevated temperatures, coupled with good thermal and electrical conductivity. The mechanical and physical properties of the Elkonite materials make them particularly suitable as the die inserts and facings for volume projection welding, flash and butt welding, electrical upsetting, electroforging and mash welding applications.

Elkonite material is also used successfully as facing on spot welding electrodes where heat balance or mechanical wear resistance are required. The initial premium cost of Elkonite material is offset by lower production cost per weld due to long die life and less electrode dressing time. The high stability of Elkonite material insures uniform heating and prevents misalignment, resulting in a higher quality weld.
