  • Preparation of the wires as a starting material for producing a light metal alloy can be done in two ways.

  • the hot isostatic pressing is preferably carried out under a pressure of 150 MPa and a temperature of about 1000 ° C. This leads to an almost complete compaction of the particles and filling of the pore spaces. Since some of the constituents have melting points below a temperature of 1000 ° C, a combination of solid phase and liquid phase sintering occurs.
