Powder metal composition containing aluminum nitride MMC

A powder metal composition includes an aluminum (Al) powder metal, an aluminum copper (Al-Cu) powder metal, a magnesium (Mg) powder metal, a tin (Sn) powder metal, an aluminum silicon (Al-Si) powder metal, and aluminum nitride (AlN) as a metal matrix composite additive. In at least some forms, the aluminum (Al) powder metal includes fine aluminum powder metal portions. Such a powder metal composition can be compressed to form a powder metal green compact, which can be sintered to form a sintered part having composition and properties close to those of a 6061 aluminum alloy product. 一种粉末金属组合物，包含铝(Al)粉末金属、铝铜(Al-Cu)粉末金属、镁(Mg)粉末金属、锡(Sn)粉末金属、铝硅(Al-Si)粉末金属、以及作为金属基质复合材料添加剂的氮化铝(AlN)。至少在某些形式中，铝(Al)粉末金属包括细铝粉末金属部分。这种粉末金属组合物可以压缩以形成粉末金属生压坯，经烧结后可以形成烧结部件，其组成和性能接近于6061铝合金产品。
