CASTING ALLOY ON THE BASE OF ALUMINUM Russian patent published in 2004 - IPC

FIELD: nonferrous metallurgy. SUBSTANCE: the invention presents the casting alloy on the base of aluminum, that may be used in nonferrous industry, in engineering industry, ship-building and in aircraft industry, for example, in production of details of propellers. The offered casting on to base of aluminum contains magnesium, silicon, copper, titanium, zirconium, iron. At that it additionally contains chromium, molybdenum, wolfram, manganese, cobalt, nickel, boron and carbon at a following ratio of the components (in mass %): a magnesium - 3.0-22.0, silicon - 2.8-10.0, copper - 0.5-2.5, titanium - 0.05-1.0, zirconium - 0.05-1.0, iron - 0.05-1.0, chromium - 0.05-1.0, molybdenum - 0.05-0.3, wolfram - 0.05-0.5, manganese - 0.05-1.0, cobalt -0.05-1.5, nickel - 0.05-1.5, boron - 0.05-1.0, carbon - 0.05-0.5, aluminum - the rest. Technical result: increase of processing characteristics of the alloy in combination with high strength, high- temperature strength and rust resistance. EFFECT: the casting alloy has increased processing characteristics, high strength, high-temperature strength and rust resistance. 1 tbl
