Aluminium bottle caps - The Innovative 5801 alloy

5801 is a new aluminium alloy developed by Gränges Konin, dedicated for high pressure bottle closures. New chemical composition and properly designed technology of production allow the pressing of high caps resistant to high pressure. The alloys are characterized by higher mechanical properties than other alloys, which are used for bottle caps like EN AW-8011A. Excellent adhesion of a varnish and high thermal resistance make this material perfectly suitable for the lacquering processes. For maximal reducing of scrap rate during deep drawing process, 5801 aluminium alloys sheets show very low earing, caused by planar anisotropy.
