DEFORMABLE THERMALLY NON-HARDENABLE ALUMINIUM-BASED ALLOY Russian patent published in 2011 - IPC C22C21/08 

FIELD: metallurgy.

SUBSTANCE: Invention relates to metallurgy and may be sued in producing strained semi-finished products from thermally non-hardenable welded aluminium-based alloys used as structural and semiconductor material, primarily, in aerospace and nuclear engineering. Aluminium-base alloy comprises the following components in wt %: magnesium - 1.8-2.4, scandium - 0.2-0.4, zirconium - 0,1-0.2, cerium - 0.0001-0.005, iron - 0.01-0.15, silicon - 0.01-0.1, aluminium making the rest. Note here that iron-to-silicon content ratio may not be less than unity.

EFFECT: higher strength and conductivity, hence, reduced weight.
