Titanium carbide is widely used in cutting tools and wear-resistant coatings due to its exceptional hardness and high melting point. It is a key component in cemented carbide tools, enhancing their ability to withstand high temperatures and resist abrasion during machining of metals and alloys. Its thermal stability makes it suitable for use in high-speed cutting applications.

It is also applied as a coating on tool bits and dies through chemical vapor deposition, significantly extending tool life. In aerospace and defense, titanium carbide is used in armor materials and missile components for its ability to resist impact and penetration.

Additionally, it serves in the production of wear parts such as seals, bearings, and nozzles where extreme mechanical stress and heat are present. Its electrical conductivity allows use in certain electrical applications, including resistors and electrodes. Titanium carbide is also being explored in composite materials for advanced structural applications and as a reinforcement in metal matrix composites.
