ALLOY OF ALUMINUM-MANGANESE SYSTEM AND PRODUCT OF THIS ALLOY Russian patent published in 2003 - IPC

FIELD: nonferrous metallurgy; production of cold-rolled thin sheets for products cool shaping. SUBSTANCE: invention presents the alloys made on the basis of aluminum of Al-Mn system and used for production of the thin cold-rolled sheets for the following cool shaping of complex form products: vessels, containers, cans and jars as well used in welded constructions. Presented alloy and a product made of it contain the following components, mass %: manganese 0.3-1.5, iron 0.05-0.9, nickel and /or a cobalt 0.001-0.3, at least, one element from the group, that includes titanium, chromium, zirconium, scandium, vanadium, molybdenum, hafnium, boron or carbon 0.00001-0.35, the rest is aluminum, at that Mn/Fn>1, Mn/(Co and/or Ni)≥2. In some cases it may be made in the form of a vessel, the heat exchanger or as a part of a jar to store beverages. EFFECT: decrease of an anisotropy of mechanical characteristics of the thin cold-rolled sheets, increase of their mechanical properties, plasticities, products life service, list of products, decrease of labor input of their manufacture. 6 cl, 2 tbl
