Elkonite Copper Tungsten
Elkonite Copper Tungsten® Alloy normally indicated to WCu alloys from WCu50 to WCu10 . RWMA 1W3, RWMA 3W3, RWMA 3W53, RWMA 5W3, RWMA 10W3
RWMA 10W53. RWMA Class 10, RWMA Class 11, RWMA Class 12 which normally used in welding .
Elkonite Copper Tungsten® alloys are commonly used in electrical & electrical/thermal applications.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.They are also 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.
