Abstract
Process to prevent corrosión of aluminum and aluminum alloys in solutions containing sulfuric acid and/or phosphoric acid, characterized by incorporating soluble aminoalkyl polyphosphonic acid solutions with 3 or more polyphosphonic acid groups in the molecule and with a group characteristic, at least, of the general formula ** (see formula) ** Where X and y are hydrogen or an alkyl radical having 1 to 4 carbon atoms, in amounts of 0.5 to 5% by weight, based on the content of phosphoric acid or sulfuric acid in the solutions.
