What metal is known for being a key alloy in cutting tools but is also relatively expensive?

Tungsten is known for being a key alloy in cutting tools due to its exceptional hardness and high melting point. These properties make tungsten ideal for creating materials that can withstand the high temperatures and mechanical stresses encountered during metal cutting processes. When used in toolmaking, tungsten typically forms part of tungsten carbide, which exhibits outstanding wear resistance and toughness, essential for maintaining tool performance over extended periods.

Despite its excellent qualities, tungsten is relatively expensive compared to other metals, which can impact the overall cost of manufacturing cutting tools. Its price reflects not only the extraction and processing costs but also its significant performance benefits, making it a valuable choice despite the higher investment.
