Abstract
A powder metal composition providing a powder metal material to be compacted, sintered, and heat treated to be comparable to wrought 6013 aluminum alloy. The powder metal composition includes an aluminum base powder metal, an aluminum-silicon powder metal, an aluminum-copper powder metal, and an elemental magnesium powder metal. A weight percent of silicon in the powder metal composition is in a range of 0.6 to 1.0 wt % of the powder metal composition, a weight percent of copper in the powder metal composition is in a range of 0.7 to 1.1 wt % of the powder metal composition, and a weight percent of magnesium in the powder metal composition is in a range of 0.8 to 1.2 wt % of the powder metal composition. This powder metal is compactable to form a green compact which is further sinterable and heat treatable to provide a powder metal composition comparable to wrought 6013 aluminum alloy.
