Abstract

Process for preventing corrosión of aluminum and aluminum alloys in hydrochloric solutions at temperatures between 0 and 30º c, characterized by adding to hydrochloric solutions with a concentration of 0.1 to 12% by weight of soluble aminomethylene phosphonic acid hcl with two groups of phosphonic acid at least in the molecule and a characteristic group of the general formula ** (see formula) ** Or their salts, in a concentration of 0.5 to 20% by weight with respect to the hcl content.
