The invention offers an aluminum alloy that not only has high hardness accompanied by balanced ductility but also has high toughness and superior processability. The invention also offers a method for manufacturing an aluminum-alloy member that not only has high hardness accompanied by balanced ductility but also has high toughness and superior processability. The aluminum alloy comprises (1) not less than 0.1 wt. % and not more than 8 wt. % Constituent A comprising one or more kinds of elements selected from the group consisting of titanium, vanadium, hafnium, and zirconium, (2) not less than 0.1 wt. % and not more than 20 wt. % Constituent B comprising one or more kinds of elements selected from the group consisting of lanthanum, cerium, praseodymium, neodymium, mischmetal, calcium, strontium, and barium, and (3) not less than 0.1 wt. % and not more than 20 wt. % Constituent C comprising one or more kinds of elements selected from the group consisting of magnesium and lithium optionally further comprising not less than 0.1wt.% and not more than 5wt.% Constituent D comprising one or more kinds of elements selected from the group consisting of niobium, molybdenum, silver, iron, cobalt, tantalum, and tungsten. In a second aspect the Al-alloy comprises the constituents D, B and C in the above specified amounts. |
