An aluminum alloy containing magnesium (Mg) between 3.0 and 4.0 wt. %, manganese (Mn) between 0.5 and 1.0 wt. %, copper (Cu) between 0.2 and 0.6 wt. %, iron (Fe) between 0.05 and 0.4 wt. % and remaining obligatory trace elements, has an electrical conductivity after baking of 30 to 32% IACS, a yield strength of 320 MPa or more and a ratio of decrease in buckling strength after retort-treatment to that immediately after manufacturing the can end of less than 10%. This an aluminum alloy sheet for can ends has an excellent corrosion resistance, complete lack of stress corrosion cracking, or age softening resistance, maintains the a high buckling strength obtained subsequent to the manufacture of a can, even after retort treatment and storage at room temperature. The aluminum alloy sheet of this invention is particularly suitable for use as a can end for non-carbonated beverages and has the potential for even thinner aluminum alloy sheet formation.

Aluminum alloy sheet for easy-open can ends having excellent corrosion

A method for manufacturing rare earth-iron magnetostrictive materials such as Tb.sub.x Dy.sub.1-x Fe.sub.2-w wherein 0.20.ltoreq.x.ltoreq.1.00 and 0.ltoreq.w.ltoreq.0.20. Rare earth and iron raw materials are continuously fed into a plasma arc melting furnace having a plasma arc torch and a water-cooled bottomless elongated mold located beneath the torch. The raw materials are melted together by plasma flames to form a pool of a molten alloy at the top of the mold. Heat is removed from the melt by water cooling through the mold, thereby causing the melt to solidify progressively from the bottom thereof. The solidified body is continuously pulled down in the mold.
