Mg, 0.60-0.95 wt. % Si, where the (wt. % Mg)/(wt. % Si) is from 1.30 to 1.90, 0.275-0.50 wt. % Cu, and from 0.05 to 1.0 wt. % of at least one secondary element, wherein the secondary element is selected from the group consisting of V, Fe, Cr, Mn, Zr, Ti, and combinations thereof. | 01-16-2014 |
20140377128 | ALUMINUM ALLOY COMPOSITION WITH IMPROVED ELEVATED TEMPERATURE MECHANICAL PROPERTIES - 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. | 12-25-2014 |
20150376741 | ROLLED ALUMINUM ALLOY MATERIAL - A rolled aluminum alloy material is provided with excellent strength and press workability and with which a poor and patchy appearance is less likely to occur after the alumite treatment. The rolled aluminum alloy material can be utilized for components of a bicycle crank. The rolled aluminum alloy material has a component composition comprising 0.6-1.4 wt % of Mg, 0.3-1.0 wt % of Si, 0.1-0.5 wt % of Cu, 0.02-0.4 wt % of Cr, and 0.1-0.6 wt % of Mn, and Al and inevitable impurities as the remainder. | 12-31-2015 |
