Abstract : This report describes a study which was performed to evaluate four heat-treatable high-strength aluminum alloys as substitute material for alloy 7001 in the manufacture of the LAW rocket. The results show that, in terms of strength and resistance to stress corrosion cracking, alloys such as X7050, specially processed 7175, and PM94 (a powder metallurgy alloy) can be superior to alloy 7001-T6. However, upon consideration of other factors such as availability and cost, alloy X7050 represents the best choice of an alternate alloy. (Author)
