Aleris announced it now offers 5083–H128, the newly developed aluminum alloy temper for marine applications that meets the new standards for marine plate as specified in ASTM's B928-13 standard. ASTM is an internationally recognized standards organization that develops and publishes specifications for a wide range of materials, products, systems and services. Marine plate is used in applications such as ship and vessel construction. While exposure to elevated temperatures can increase the susceptibility of these types of alloys to corrosion, Aleris' new process for developing marine plate temper demonstrates enhanced corrosion resistance in such conditions.
