Can tungsten be made from tungsten?

8. Electrical Conductivity - Tungsten carbide is in the same range as tool steel and carbon steel. 9. Specific Heat - Tungsten carbide ranges from about 50% to 70% as high as carbon steel. 10. Weight - The specific gravity of tungsten carbide is from 1-1/2 to 2 times that of carbon steel. 11.

Tungsten carbide micro drill is used to obtain through-holes in the printed circuit board (PCB). Although more brittle than conventional high speed steel (HSS) drills, tungsten carbide bits designed specifically for PCB drilling will yield far superior hole wall quality.

Silver Tungsten Carbide . The silver and tungsten carbide composites exhibit initial resistance to formation of surface films and possess good antiweld and arc erosion resistance. These are specially used for devices requiring more consistent millivolt drop as compare to silver tungsten. Modison manufacture these composites by powder metallurgy.

Our tungsten carbide-silver (WCAg) switch contacts are perfect for your power needs. They reliably switch short-circuit current in vacuum contactors in the 7.2 - 24 kV range, for instance, and have a life of more than a million switching cycles. We manufacture WCAg compliant with the international standard ASTM B 663-94. high arc erosion resistance

Tungsten carbide-based hard alloys include tungsten-cobalt (YG), tungsten-cobalt-titanium (YT), and rare-carbide (YW). 1.YG8 (K30) hardness ≥89.0 is suitable for rough turning, rough planing, rough milling, general and deep hole drilling and reaming, and reaming when cast iron, non-ferrous metals and their alloys, non-metallic materials have

Silver tungsten carbide (AgWC) contact materials are widely used as arcing contacts in circuit breaker applications. An asymmetric combination with silver graphite (AgC) stationary contact is typical for IEC standard devices, while in UL breakers AgWC is often applied symmetric as movable and stationary contact.
