Properties of Tungsten Carbide Balls: Hardness, Density, Wear Resistance","og_description":"Tungsten carbide balls are known for their exceptional performance in many industries. They are used in bearings, valves, measuring tools, oil &amp; gas equipment, and even pens. Their popularity comes from three main properties: hardness, density, and wear resistance. In this guide, we will explain each property in simple terms, show why it matters, and help you understand why tungsten carbide balls are often the best choice. Hardness of Tungsten Carbide Balls Hardness is the ability of a material to resist scratching, cutting, or deformation. Tungsten carbide balls have a hardness of about 89\u201394 HRA, which is much harder than steel and close to diamond on the hardness scale.
