DEFORMED NON-HEAT-TREATABLE ALLOY ON BASIS OF ALUMINIUM Russian patent published in 2010 - IPC C22C21/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy field, particularly to deformed non-heat-treatable aluminium alloys, provided for application in the form of deformed semi-finished products in the capacity of structural material principally for soldered structures of heat-exchangers of spaceships, received by methods of brazing. Alloy on the aluminium base contains the following components, wt %: manganese 0.3-0.6, magnesium 0.9-1.4, scandium 0.17-0.35, zirconium 0.05-0.12, titanium 0.01-0.05, cerium 0.0001-0.005, aluminium - the rest.

EFFECT: obtaining alloy, allowing increasing strength after brazing that provides reduction of mass and overall dimensions of manufactured structures.
