Aleris International Inc., Cleveland, Ohio, has developed 5083-H128, an aluminum alloy temper for marine applications. Exposure to elevated temperatures can increase the susceptibility of aluminum alloys to corrosion, but the new process enables improved resistance in these conditions. It meets the new standards for marine plate as specified in ASTM’s B928-13 standard. Aluminum 5083-H128 passes the intergranular corrosion test requirements of ASTM’s G67 standard, and the exfoliation resistance requirements of ASTM’s G66 standard, after being exposed to a temperature of 100°C for seven days.
“This new innovation meets the requirements of our marine and shipyard customers who need an aluminum plate solution that can meet this standard of corrosion resistance in the most extreme conditions,” said Brian Hesse, sales director – Commercial and Defense Plate for the Americas. “We are also looking at applying the H128 temper to other plate products.”
Aleris is a leading supplier of aluminum solutions to the world’s defense industry. The company’s high-performance marine and defense plate products are available in extreme thicknesses and widths, providing solutions to a variety of military challenges.
