An investigation was undertaken to determine the aluminum tolerance of Zircaloy-2, the alloy of zirconium presently used in applications requiring resistance to corrosion in hjgh-temperature water. Alloys of Zircaloy-2 containing different amounts of aluminum from 100 to 380 ppm were prepared and testcd in hightemperature water and steam for resistnnce to corrosion. It was found tht with aluminum content as low as 100 ppm corrosion resistance is not equal to tht of specification grade Zircaloy-2 whose maximum aluminum content is 50 ppm. It was also found that corrosion resistance decreases with increasing aluminum content over the range of 100 io 380 ppm aluminum. (auth)
