Tungsten alloy, often referred to as tungsten carbide or tungsten-hard, is a strong and wear-resistant alloy composed of tungsten and other elements, typically iron, cobalt, and carbon. The tungsten content in these alloys is usually around 80 to 90%. The primary application of tungsten alloys hinges on their exceptional hardness, high melting point, and resistance to wear and abrasion.

These properties make tungsten alloys a suitable choice for various industrial components, including wear-resistant parts, cutting tools, and hardware. Some examples of their uses include armor-piercing projectiles, high-speed cutting tools, and wear-resistant components in heavy machinery, mining, and construction equipment. The doping of cobalt in tungsten enhances its magnetic properties, allowing for potential applications in the magnetic field and particle accelerator areas.

The production of tungsten alloys typically involves powder metallurgy techniques or casting methods. Compacting tungsten and other alloying elements through high-pressure techniques allows for precise control over composition and properties. When combined with carbide forming elements, the tungsten-carbon interaction leads to twinned tungsten cores, producing an increase in mechanical strength and wear resistance.

Investigations into the use of composite materials composed of alternating layers of tungsten and other elements have demonstrated further enhanced regulatory properties and higher adaptability to service. However, processing these materials can be more challenging due to the bonding difficulties surrounding layered structures. Despite these challenges, continuous advances in tungsten alloy production and properties are expanding the range of potential applications in industry.
