Used as a key component in cutting tools and wear-resistant coatings due to its extreme hardness and high melting point. Commonly found in industrial machining applications for turning, milling, and drilling hard metals. Applied as a surface coating via chemical vapor deposition to extend tool life. Also utilized in aerospace components and high-temperature parts because of its thermal stability and resistance to oxidation. Plays a role in some ceramic composites and is explored for use in certain electronic and semiconductor applications.
