PRODUCTS OUT OF ALUMINIUM ALLOY AND METHOD OF ARTIFICIAL AGING Russian patent published in 2008 - IPC C22F1/53 C22C21/10 

FIELD: metallurgy.

SUBSTANCE: product out of aluminum alloy consisting out of the following elements, mas.%: zinc 6-10, magnesium 1.2-1.9, copper 1.2-2.2; at that one or several elements are chosen out of a group, consisting of zirconium up to 0.4, scandium up to 0.4 and hafnium up to 0.3, at that aluminium and tramp additives- the rest. The said alloy optionally contains titanium up to 0.06, calcium up to 0.03, strontium up to 0.03, beryllium up to 0.002. The product with a large cross section is treated for transforming it into a hard solutuion, then tempered and artificially aged. The product with a small cross section is slowly tempered. There are suggested the following parts fabricated out of the said alloy: an aircraft wing, a structural component and a method of its fabrication, a compartment component of an airlock caisson, a profiled plate, an aircraft wing of a high carrying capacity and an aircraft of a high lading capacity.

EFFECT: products developed for higher characteristics of hardness and improved characteristics of wear and fracture resistance.
