I. Development History of Tungsten Carbide Dies

As a novel material, tungsten carbide has garnered widespread attention since its inception in the early 20th century due to its unique physical and chemical properties. Tungsten carbide is primarily manufactured by compressing and sintering refractory metal carbides (such as tungsten carbide, WC) and metal binders (such as cobalt, Co) through the powder metallurgy method. Its high hardness, strength, wear resistance, and high elastic modulus make it an ideal material for die manufacturing.
