1. A method for producing a metal matrix composite produced from a powder mixture comprising: a composition comprising aluminium having a standard of purity of at least 95.0%, up to 1% weight of hexagonal boron nitride, and up to 2% weight of abherent, the method comprising:
comminuting the aluminium powder mechanically, wherein the comminuting comprises mechanically communiting an aluminum starting material having an average grain diameter ranging from 1 mm to 5 mm to the aluminum powder having an average grain diameter of at most 500 μm;
mixing the material components, in powder form, and
processing the mixture, by primary shaping or extrusion or sintering or 3D printing, to form a bar, a semi-finished product, or a component.
