Paragraph starter

The exceptional hardness and high melting point of tungsten carbide, as detailed by Penrice (2001), make it the material of choice for approximately 65% of cutting and mining tool applications. This dominance necessitates specialized powder metallurgy fabrication techniques and has spurred the development of effective recycling processes, such as zinc treatment and vacuum distillation, to recover valuable tungsten from used tools. Designers should consider these material properties and lifecycle implications when developing products for demanding environments.
