Abstract
An aluminum alloy includes, in weight percent, 0.50-1.30% Si, 0.2-0.60% Fe, 0.15% max Cu, 0.5-0.90% Mn, 0.6-1.0% Mg, and 0.20% max Cr, the balance being aluminum and unavoidable impurities. The alloy may include excess Mg over the amount that can be occupied by Mg—Si precipitates. The alloy may be utilized as a matrix material for a composite that includes a filler material dispersed in the matrix material. One such composite may include boron carbide as a filler material, and the resultant composite may be used for neutron shielding applications.
