The aluminum alloy includes 0.50-1.30% Si, 0.2-0.60% Fe, 0.15% Cu, 0.5-0.90% Mn, 0.6-1.0% Mg, and up to 0.20% Cr in weight percent, The remainder is aluminum and unavoidable impurities. The alloy may contain an excess of Mg exceeding an amount that can be occupied by the Mg-Si precipitate. The alloy may be utilized as a matrix material for composites comprising dispersed filler materials in the matrix material. One such composite may comprise boron carbide as a filler material, and the resulting composite may be used for neutron shielding applications. |
