ALUMINIUM SHEET FOR HIGH TEMPERATURE SOLDERING WITH HIGH STRENGTH AND EXCELLENT CORROSION CHARACTERISTICS Russian patent published in 2015 - IPC C22C21/08 B32B15/01 

FIELD: metallurgy.

SUBSTANCE: invention relates to sheets from aluminium alloys for high temperature soldering, which can be used for the production of radiators. A sheet consists of a core made from an aluminium alloy and a clad material applied to at least one side of the core and made from an aluminium alloy with a lower potential than that of the core material; with that, the clad material represents the outermost layer of the sheet for high temperature soldering and is made from an aluminium alloy containing the following, wt %: 0.8 to 1.3 Mg, 0.5 to 1.5 Si, 1.0 to 2.0, preferably 1.4-1.8 Mn, ≤0.7 Fe, ≤0.1 Cu, and ≤4 Zn, ≤0.3 each of Zr, Ti, Ni, Hf, V, Cr, In, Sn, and ≤0.5 of the sum of Zr, Ti, Ni, Hf, V, Cr, In, Sn, and the rest are Al and inevitable impurities.

EFFECT: invention allows creating thin sheets from the aluminium alloy, which have high strength, good corrosion resistance and pressure processibility.
