Which metals are used as matrix metals in WC cemented carbides and TiC cermets?

What are the matrix metals used in nearly all WC cemented carbides and TiC cermets?

The matrix metals used in nearly all WC cemented carbides and TiC cermets are cobalt and nickel. These metals provide the materials with toughness and resistance to wear and corrosion.

Matrix Metals in WC Cemented Carbides and TiC Cermets

Cobalt and nickel are the two metals commonly used as matrix metals in nearly all WC cemented carbides and TiC cermets. These metals are crucial in determining the properties of the final product, such as toughness and resistance to wear and corrosion.

In the context of WC cemented carbides and TiC cermets, cobalt and nickel serve as the binders that hold the hard particles of tungsten carbide or titanium carbide together. The combination of these matrix metals with the hard carbide particles gives the materials their unique characteristics.

While cobalt and nickel are the primary matrix metals used in these materials, other metals like aluminum, chromium, lead, and tungsten are not commonly employed for this purpose. Tungsten itself is one of the main components in WC cemented carbides, but it is not used as a matrix metal. Tungsten carbide, although a key ingredient, is not utilized as a matrix metal either.

The presence of cobalt and nickel in WC cemented carbides and TiC cermets contributes to their durability and performance in various industrial applications. These matrix metals enhance the toughness of the materials, making them suitable for cutting, drilling, and other wear-resistant operations.

Therefore, when considering the matrix metals in WC cemented carbides and TiC cermets, cobalt and nickel are the essential elements that provide the materials with their distinctive properties and performance characteristics.
