Used extensively in cutting tools and machining due to its extreme hardness and resistance to wear. Commonly found in drill bits, milling cutters, and tool inserts for metalworking, mining, and construction equipment. Also used in wear-resistant parts such as seals, bearings, and nozzles. Applied in aerospace and defense for armor-piercing components and high-temperature applications. Frequently used in jewelry for durable, scratch-resistant rings. Serves as an electrode material in certain welding and electrical discharge machining processes.
