hårdmetalkugles

Hårdmetalkugler, sometimes referred to as tungsten carbide balls, are precision-engineered spherical components made from hard metal alloys, primarily tungsten carbide. These alloys are characterized by their exceptional hardness, wear resistance, and high density, making them suitable for a variety of demanding applications. The manufacturing process typically involves pressing and sintering powdered tungsten carbide mixed with a binder material, such as cobalt or nickel, under high pressure and temperature. This sintering process fuses the powder particles into a solid, dense object.

The properties of hårdmetalkugler, such as their extreme hardness (approaching that of diamond), rigidity, and resistance to deformation, make them ideal for use as bearings, especially in environments where standard steel balls would quickly fail due to wear or impact. They are also employed as valve seats and plungers in high-pressure systems, as grinding media for fine milling operations in the chemical and pharmaceutical industries, and in specialized measuring instruments where dimensional stability and accuracy are paramount. Their high density also contributes to their use in applications requiring significant mass in a small volume. The specific grade of tungsten carbide and binder content can be tailored to optimize properties like fracture toughness or corrosion resistance for particular uses.
