Products Description
Tungsten copper are equal to Elkonite Copper Tungsten material which is world-known famous brand Elkonite Copper Tungsten® Alloy which 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.
features of Elkonite Copper Tungsten
High hardness and wear resistance: The hardness is above HRB 90, and the wear resistance is better than pure copper. It is suitable for high load conditions.
Arc erosion and high temperature resistance: Tungsten matrix is resistant to high temperature, the copper phase provides conductivity, and the working temperature is up to 3000°C.
Low thermal expansion and high density: CTE as low as 4.5×10⁻⁶/K, density 15g/cm³, suitable for high-precision scenarios.
applications of Elkonite Copper Tungsten
Elkonite copper-tungsten alloy is used for spot welding and convex welding in automobile manufacturing, and the electrode life is extended by 50%.
As an electrode material, Elkonite copper-tungsten alloy has high surface quality when processing cemented carbide.
Elkonite copper-tungsten alloy is used in die-cast mold inserts and withstand high-temperature liquid metal erosion.
