Hårdmetalkugler

Hårdmetalkugler, sometimes referred to as tungsten carbide balls, are precision-engineered spheres made from cemented carbide. Cemented carbide is a composite material composed of a hard carbide phase, typically tungsten carbide (WC), and a binder metal phase, usually cobalt (Co). This combination results in a material with exceptional hardness, wear resistance, and compressive strength.

The manufacturing process for hårdmetalkugler involves sintering powdered tungsten carbide mixed with cobalt powder under high pressure and temperature. This process fuses the particles together, creating a dense and extremely hard solid. Due to their properties, these balls find application in various industries. They are commonly used in bearings, especially in high-load or abrasive environments where traditional steel balls would fail prematurely. They also serve as components in valves, pumps, and precision measuring instruments. Their high density and hardness make them suitable for use as counterweights or in specialized projectile applications. The precise dimensions and surface finish of hårdmetalkugler are critical for their performance in demanding applications.
