3D printing in Tungsten Carbide

Tungsten Carbide (WC) is an extremely hard composite made of equal parts tungsten and carbon. The result is a ceramic type material, sometimes cobalt is added to form an extremely hard metal composite (WC CO)

About Tungsten Carbide

Tungsten (W) also known as Wolfram, is a rare metal famous for having the highest melting point of all elements. Tungsten is almost always combined with other elements to form a composite to achieve the hardness tungsten alloys are known for.

Tungsten carbide (WC) is the most famous of these composites. It is a combination of tungsten and carbon. The result is a ceramic composite.

Other combinations involve cobalt, copper, bronze, chromium, iron or nickel. Tungsten is also a part of a nickel-molybdenum-chromium superalloy known as Hastelloy. In all instances the composite results in a exceptionally hard metal.
Of the alloys Tungsten Carbide Cobalt (WC CO) is often used. Tungsten Carbide Cobalt can be 3D printed using Binder Jetting technology.

Examples of applications are cutting tools and other wear resistant machine parts and  tools such as saw blades, drill bits, bearings, pistons and welding equipment.
