Tungsten Carbide

Tungsten Carbide (WC) is a dense, metal-like substance, light gray with a bluish tinge. Tungsten carbide has high decomposition points, with WC at 2770°C. WC will conduct electricity. It is hard and rigid but possesses very high strength, including compressive strength and impact resistance. Its rigidity is 2-3X the rigidity of steel and 4-6X that of cast iron and brass. The wear resistance of tungsten carbide is better than that of wear-resistance tool steels and is also corrosion-resistant and chemically resistant.

WC powders are available as fine, medium, and coarse-grained cuts.
Typical Applications

Tungsten carbide has applications in the tool and die industry for drilling and cutting tools. It is also used to manufacture sandblasting nozzles and armor-piercing bullets and is incorporated into studs to increase the traction of tires. It is also used in wear-resistant coatings in manufacturing precision components with abrasive and adhesive wear, preventing seizure problems, and for dry machining applications. Sports equipment, such as trekking poles, also employ tungsten carbide in the parts which contact hard surfaces.

Packaging Options

Jars, pails, drums, multi-ply paper bags, bulk bags, and fiberboard containers.
