Claims
- 1. An improved corrosion resistant aluminum alloy exhibiting improved sag resistant properties when used in the manufacture of brazed assemblies, said alloy consisting essentially of not less than 0.15% and not more than 0.40% chromium, not less than 0.2% and not more than 0.9% manganese, up to 0.2% iron, up to 0.1% silicon, balance essentially aluminum.
- 2. A brazed article exhibiting improved sag resistant properties and having superior corrosion resistant properties in aqueous environments comprising an aluminum alloy consisting essentially of not less than 0.15% and not more than 0.40% chromium, not less than 0.2% and not more than 0.9% manganese, up to 0.2% iron, up to 0.1% silicon, balance essentially aluminum.
- 3. An aluminum alloy according to claim 1 wherein said alloy contains reduced size and population density of second phase iron containing particles.
- 4. An aluminum alloy according to claim 1 wherein said alloy is substantially free from highly cathodic FeAl.sub.3 phase.
- 5. An aluminum alloy according to claim 1 wherein said alloy contains up to 0.1% iron.
