SINTERMETALLTEILE MIT HOMOGENER VERTEILUNG NICHT HOMOGEN SCHMELZENDER KOMPONENTEN, SOWIE VERFAHREN ZU IHRER HERSTELLUNG

摘要

Production of components and semi-finished products comprises: preparing a powder material made from light metal and alloying components, especially wear-resistant carriers; isostatically pressing into a molded body; and extruding close to the sintering temperature of the light metal. Preferred Features: The light metal is aluminum. The alloying components comprise 10-30 wt.% silicon, 0-3 wt.% magnesium, 0-5 wt.% copper, 0-7 wt.% zinc, and 0-7 wt.% iron. The wear-resistant carriers are selected from silicon and/or hard material particle additives, especially oxides, carbides and silicates in an amount of 0-30 wt.%.
