Tungsten is mixed with carbon to make a very strong, very resistant material called tungsten carbide. Tungsten carbide is the hardest of all metals. It is about 10 times harder than 18K gold, 5 times harder than tool steel, and 4 times harder than titanium. So it is suit for making cutting tools and wear-resistant tools for metalworking, drilling for oil and gas, mining, and construction. It is ideally suited for wear parts, other machine parts and dies which are subject to severe service conditions, such as high temperatures, corrosion and abrasion. In recent years, tungsten carbide has emerged as a superior alternative to steel in many industrial applications.

Because of tungsten carbide's special physical properties, it has a very wide of applications, especially for wear parts. Tungsten products can sustain high temperatures, is abrasion and corrosion resistant which makes it highly suited for wear parts, machine parts and dies. Today a very high percentage of tungsten carbide is cemented carbide used for wear parts. The extensive range of products covers from small balls for ball-point pens to big and heavy products, like hot rolls for rolling mills, punches or dies.

The most common binding material for cemented carbide wear parts and carbide mining tools is cobalt(WC-Co). The grain size of tungsten carbide hard-metals is usually fine. Ultra-fine grained is becoming more important in the area of wear parts, carbide tools for cutting, tools for cast iron, chip less forming, non ferrous alloys and wood.
