  • Creep resistant aluminium alloy for multilayer tubes
    Patent number: 8241719
    Abstract: The invention relates to an aluminum alloy product containing, in wt. %: Si 0.2 to 1.4; Fe+Mn 1.1 to 1.8; Cu 0.15 to 0.5; Mg<0.2; Ti<0.2; Zn<1.5; impurities<0.05 each, <0.2 total, balance aluminum. This aluminum alloy product has high resistance to internal pressure when used as core layer for welded multilayer tubing. The invention relates also to a method of manufacturing such alloy product, and the use of such alloy in welded multilayer tubes.
