Abstract
A method for producing a corrosion resistant aluminum alloy extrusion. The method includes providing molten alloy with a composition comprising ≤0.30, % by weight of silicon, ≤0.40, % by weight of iron, 0.01-0.6% manganese, ≤0.30, % magnesium, ≤0.70, % zinc, 0.05-0.35% chromium, 0.02-0.20% zirconium, ≤0.25% titanium, ≤0.20% vanadium, ≤0.10% copper, up to 0.15% by weight of other impurities, each not greater than 0.03% by weight, and the balance aluminum. The method includes casting the alloy into an extrusion billet, subjecting the billet to a homogenization treatment at a holding temperature of 550 to 620 deg.C for 6 to 10 hours, heating the billet to a temperature of 400 to 550 deg.C, and extruding the billet to a tube.
