Pure Micron Tungsten Yarn Tungsten Filament Tungsten Wire
Product Introduction
We will continue to put effort into R&D to ensure that our Pure Tungsten Rod, ultrafine tungsten wire, Pure Zirconium Metal Rod technology is at the forefront of the industry. We deeply build three systems: lean production with zero-defect quality management as the core, integrated product development as the basis and marketing service supported by information technology. On the road of future development, we will always insist on producing high-quality products and providing perfect services. The company not only has an excellent management team, but also complete hardware facilities and experienced professional teams. A sound and reasonable management system enables the company to do better in all aspects.
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.
