Tunsten Carbide

Overview

Tungsten carbide (WC) is an inorganic chemical compound containing equal parts of tungsten and carbon atoms. In its most basic form, it is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, tools,abrasives, as well as. Tungsten carbide is approximately three times stiffer than steel, and is much denser than steel or titanium. It is comparable with corundum in hardness and can only be polished and finished with abrasives of superior hardness such assilicon carbide, cubic boron nitride. 

CAS#: 12070-12-1
The tungsten metal powder can be converted to tungsten carbide (WC) by reaction with pure carbon powder, e.g. carbon black, at 900 - 2200°C in pusher or batch furnaces. Tungsten carbide behaves similarly to unalloyed tungsten and is resistant to chemical attack, although it reacts strongly with chlorine to form tungsten hexachloride. Because of its hardness, it is the main constituent in cemented carbide. As the most important tungsten compound, tungsten carbide is used to make wear-resistant abrasives and cutters and knives for drills, circular saws, milling and turning tools used by the metalworking, woodworking, mining, petroleum and construction industries and accounts for about 60% of current tungsten consumption.

Tungsten Carbide Rod

Applications:

Cast tungsten carbide welding rods are mainly used as pile-up welding on the surface of metal parts to enhance its wear ability. Generally, YZ20 - 30g is used in thick electrode surfacing work and work requirements for scraping role of the parts and components. If required welding layer is 3 to 4 mm, using YZ30 - 40g multi-electrode; and if surfacing request is thin layer formation, the best choice is YZ40 - 60g or more granular tubular alloy electrode.

Casting Tungsten Carbide Powder

CAS#: 12070-12-1
By melting tungsten metal and tungsten monocarbide (WC) together, a eutectic composition of WC and W2C is formed. This melt is cast and rapidly quenched to form extremely hard solid particles having a fine crystal structure. A tough, feather-like structure is preferred over the brittle, blocky structure obtained by insufficient quenching. The solids are crushed and classified to various mesh sizes.
