摘要: Proposed is a highly corrosion-resistant aluminum alloy including one or more components selected from among 0.1 wt.% or less (except for 0 wt.%) of Cu, 0.15 wt.% or less (except for 0 wt.%) of Si, 0.2 wt.% or less (except for 0 wt.%) of Fe, 0.9 to 1.5 wt.% of Mn, 0.03 to 0.15wt.% of Ti, 0.03 to 0.15 wt.% of Cr, and 0.03 to 0.15 wt.% of Zr, and the remaining proportion of aluminum (Al) and unavoidable impurities. The highly corrosion-resistant aluminum alloy contains Ti, Cr, and Zr in a predetermined weight ratio or in equal weight percentages (wt.%), thereby exhibiting improved corrosion resistance in a saline water environment while exhibiting excellent levels in tensile strength and yield strength.

摘要: Provided herein are highly-formable aluminum alloys and methods of making such alloys. The method of preparing aluminum alloys described herein can include a low final cold reduction step and/or an optional inter-annealing step to produce randomly distributed crystallographic texture components that produce an isotropic aluminum alloy product exhibiting improved formability and deep drawability. The methods described herein result in aluminum alloy microstructures having a balance of alpha fibers and beta fibers that promote improved formability of aluminum alloy sheets. The resulting improvements in quality allow for shaping processes with reduced rates of spoilage.

摘要: Es wird ein Verfahren zum Aushärten eines Gussteils aus einer Aluminiumlegierung und ein damit hergestelltes Gussteil gezeigt. Um ein formgenaues Gussteil, insbesondere Druckgussteil, mit hohen Bruchdehnungs- und Zugfestigkeitswerten zu schaffen, wird eine mehrstufige Wärmebehandlung vorgeschlagen.
