Elkonite® is the registered trademark of Sherbrooke Metals used to identify a group of metal compositions whose elements consist basically of the refractory metals tungsten 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 Sherbrooke Metals Elkonite® materials make them particularly suitable as the die inserts and facings for volume projection welding, flash and butt welding, electrical upsetting and electro-forging applications.
Elkonite® Copper-Tungsten is also used successfully as facing on spot welding electrodes where heat balance or mechanical wear resistance is required. The initial premium cost of Elkonite® Copper-Tungsten is offset by lower production cost per weld due to long die life and less electrode dressing time. The high stability of Elkonite® Copper-Tungsten ensures uniform heating and prevents misalignment resulting in a higher quality weld.
