Abstract: An aluminum alloy for making an extruded and brazed aluminum product, the aluminum alloy comprising, in weight percent, 0.10-0.20 Zn to improve corrosion resistance, 0.9-1.2 Mn, 0.03-0.10 Mg, the sum of Mg and Mn being at least 0.99 to maintain or improve strength, 0.15 to 0.30 Fe to control grain size, up to 0.15 Si, up to 0.03 Cu, up to 0.04 Ti, the balance being aluminum and unavoidable impurities. The alloy may be in the form of extrusion ingots or extruded and brazed aluminum products. A process for making an extruded and brazed aluminum product from the alloy involves homogenizing, extruding, optionally working, and brazing the alloy to form the product.
