CARBIDE Aluminium

Carbide (cemented carbide) is a composite material made from metal carbides (such as tungsten carbide (WC)) and a metal binder (such as cobalt (Co), nickel (Ni), iron (Fe), etc.) through powder metallurgy. It is renowned for its high hardness, wear resistance, heat resistance, and corrosion resistance, and is widely used in cutting tools, molds, and mining tools.

The main characteristics of cemented carbide include:

High Hardness: Cemented carbide's hardness is far higher than that of ordinary steel, second only to diamond.

Wear Resistance: Cemented carbide maintains excellent wear resistance even under high temperature and high pressure.

Heat Resistance: Cemented carbide maintains high hardness and stability at high temperatures, making it suitable for cutting and machining in high-temperature environments.

Corrosion Resistance: It offers excellent resistance to corrosive media such as acids and alkalis.

Differences between cemented carbide and high-speed steel:

Composition: Cemented carbide is primarily composed of metal carbides and a binder metal, while high-speed steel is a high-carbon, high-alloy steel containing significant amounts of elements such as tungsten, molybdenum, chromium, cobalt, and vanadium. Performance: Carbide generally offers better hardness, red hardness, wear resistance, and heat resistance than high-speed steel.

In summary, carbide is indeed a type of carbide widely used in modern industry.
