Abstract

A nut is made by compacting powdered metal in a mould. The metal may be mixed with a lubricant, e.g. wax, or can be mixed to a slurry-like consistency with a volatile liquid. The mould may be lined with cemented carbides, and the core may be of steel or cemented carbide and may be of the solid or collapsible type. After pressing the nuts are sintered, e.g. in a protective atmosphere at a temperature between 10% and 30% below the melting point of the metal or alloy used. The nuts may be re-pressed to size after sintering, and partly or completely hardened, and by adding small amounts of an alloying element. e.g. copper, nickel, molybdenum, they can be precipitation hardened.
