Abstract : The report presents the results of an evaluation of three tempers of commercially fabricated alloy MA15 plate in 1 in. to 6 in. thickness. Compared at equal strengths, MA15 developed higher resistance to stress-corrosion cracking, greater resistance to exfoliation corrosion, higher toughness, and better fatigue performance than established commercial aluminum alloys. Compared at equal resistance to stress-corrosion cracking, MAl5 developed substantially higher strength than established commercial aluminum alloys. Field testing of this material is recommended.
