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.

Abstract: An aluminum alloy composition includes, in weight percent: 0.5-0.7 manganese; 0.05-0.15 iron; 0.3-0.5 silicon; 0.020 max nickel; 0.05-0.15 titanium; 0.01 max copper; and 0.10 max zinc, with the balance being aluminum and unavoidable impurities. The alloy may also have a combined amount of manganese and silicon of at least 0.8 wt. % and/or a Mn/Si ratio of 2.25 or less. The alloy may tolerate higher nickel contents than existing alloys, while providing increased corrosion resistance, as well as similar extrudability, strength, and performance. Billets or other intermediate products formed of the alloy may be homogenized at 500-595° C. and controlled cooled at 400° C. per hour or less. The homogenized billet may be extruded into an extruded product, such as an aluminum alloy heat exchanger tube.
