摘要

PROBLEM TO BE SOLVED: To provide an aluminum material excellent in high temp. strength without deteriorating workability. SOLUTION: This material is an aluminum material produced by subjecting a billet to hot extrusion and then to cold working. This aluminum material has an alloy composition which consists of, by weight, 0.5-1.8% Mn and the balance Al with impurities and in which, as impurities, the contents of Fe, Si, Mg, Cu, and other elements are controlled to =0.4%, =0.4%, =0.5%, =0.5% and =0.2 respectively, and also has an alloy structure in which an Al-Mn type precipitate has =0.4 μm major axis and is present by =1 piece/μm2 .
