Abstract: A composition for corrosion control in aqueous systems, the composition providing a formulation of a concentrated aluminum corrosion inhibitor; and (i) a polycarboxylic acid polymer, (ii) a sulfonic acid polymer, (iii) a combination of a polycarboxylic acid and a polysulfonic acid, (iv) an organic phosphonate, (v) a combination of a phosphonate and a polycarboxylic acid, or (vi) a combination of a phosphonate and a polysulfonic acid. A method for corrosion control in aqueous systems, the method providing a concentrated formulation, the concentrated formulation having an aluminum corrosion inhibitor and (i) a polycarboxylic acid polymer, (ii) a sulfonic acid polymer, (iii) a combination of a polycarboxylic acid and a polysulfonic acid, (iv) an organic phosphonate, (v) a combination of a phosphonate and a polycarboxylic acid, or (vi) a combination of a phosphonate and a polysulfonic acid; and delivering the concentrated formulation to an aqueous stream.
