What Makes Tungsten Carbide the King of Cutting Blades?
Tungsten carbide blades have revolutionized precision cutting in the world. Its unmatched performance is observed and experienced in almost every industry. This blade, made primarily of tungsten carbide particles bonded in a metal matrix, marked a high water mark in modern technology balancing extreme hardness against tremendous toughness. Tungsten carbide traces its origin to the early 20th century when researchers searched for something harder than steel. A revolution in cutting technology began in 1923 with the introduction of the first tungsten carbide cutting tools. As carbide has improved in composition as well as manufacturing processes, we have come to use these high-performance blades. 1. Properties of Tungsten Carbide Blades Hardness and Toughness: Blades containing tungsten carbide are extremely hard, up to 9.5 on the Mohs scale when compared to diamond at 10. The hardness is directly associated with good abrasion resistance so that blades do not lose their cutting edge for as long as any ordinary steel blade could, a scenario where change is made less frequently in production, idle time is reduced, and productivity is increased in industries. Thermal Conductivity: Although much less thermally conductive than many metals, tungsten carbide’s thermal properties are very suitable in cutting applications. Its moderate thermal conductivity helps to dissipate heat generated during the cutting process, avoiding overheating of the blade, as well as of the material undergoing cuts. This characteristic is especially important at higher-speed cutting operations where the buildup of heat can be a problem. Chemical Resistance: Tungsten carbide is resistant to most chemicals and corrosive materials. It is made of this material because it can be used under harsh environments or when cutting materials that can react to, or corrode, other blade materials. Acidic woods, corrosive metals and many other materials- its blades maintain their integrity and performance. Edge Retention: The most coveted attribute of tungsten carbide knives is edge retention. The balance between hardness and toughness allows the knife to retain a sharp cutting edge that could easily last much longer than the conventional blades. This leads to a generally more consistent cut, lessening the need to resharpen repeatedly or replace several times.
