Studies on Corrosion at Power Generation Stations Using Acid River Water (17th Report). Field Test of Aluminum Alloys

Abstract

The field tests of commercial pure aluminum, 3S and 61S were carried on at the electric power generation stations using acid river water in the North Eastern District of Japan. The corrosion rates of the specimens were measured by the change of the tensile strength. Three hundred specimens were used in the tests. Commercial pure aluminum is excellently proof to acid river water and it is probably fit for practical use. 3S and 61S were severely corroded within eight months.
