Abstract: A cast article of aluminum alloy is produced by pouring into a mold a molten Al-Si-Cu type or Al-Si-Cu-mg type casting alloy having an antimony (Sb) content in the range of about 0.03%-1.0% by weight and, while the alloy cast body is cooling following complete solidification but before its temperature has fallen below 450.degree. C., placing the solidified cast body into a heating furnace kept at temperatures in the range of from 480.degree. to 530.degree. C. and retaining it at an intermediately high-temperature within that temperature range for not more than two hours, subsequently quenching said cast body in cold water or hot water and thereafter subjecting the quenched cast body to a treatment for artificial aging at temperatures in the range of from 140.degree. to 230.degree. C. for a period in the range of from one to 12 hours.

Abstract: A wrought aluminum alloy sheet product suitable for forming into heat exchanger fins is disclosed. The sheet product contains essentially 2 to 13 wt. % Si, 4 max, wt. % Zn, 0.005 to 0.5 wt. % Sr, up to 1 wt. % each of Fe and Cu, the balance essentially aluminum and incidental impurities. The sheet product is characterized by a substantially uniform distribution of relatively fine generally equiaxed constituents comprised mainly of elemental silicon.

Abstract: A heat-resistant aluminum alloy for electrical use, having high heat resistance and conductivity, obtained by subjecting an Al-Zr alloy comprising 0.23-0.35% Zr, the balance consisting of ordinary impurities and aluminum, to melting, casting, hot rolling in the state of high temperature or continuous heating, cold working to a predetermined size, ageing at a temperature within the range of 310.degree. C.-390.degree. C. for 50-400 hours so that Al.sub.3 Zr is dispersed uniformly and in fine particles, and, optionally, further cold working to a degree not exceeding 30% of reduction of area. The resultant aluminum alloy has conductivity in excess of 58% IACS, same strength as 1350 aluminum wire, and 10% softening temperature higher than 400.degree. C. at one hour annealing.

Abstract: Fine-grained, formable Al-Mn alloy sheet is produced from strip-cast slab (e.g. twin-roll-cast slab) by including 1.3-2.3% Mn in the alloy, slab annealing the workpiece by heating it to precipitate most of the Mn in fine intermetallic particles, cold rolling the workpiece to sheet of final gauge with an interanneal performed (between successive cold rolling stages) under nonrecrystallizing conditions to reduce the amount of Mn present in solid solution in the aluminum matrix, and annealing the final sheet.
