The purpose of the proposed revisions is addition of tensile property data and corrosion testing requirements for a high magnesium aluminum alloy extrusion product to ASTM B928/B928M which currently only includes properties and testing requirements for high magnesium aluminum alloy sheet and plate products. Various marine product users have expressed a need for a specification for high magnesium extruded products with similar corrosion testing requirements to those in ASTMB928/B928M for sheet and plate products. Currently, 5383-H116 is the only high magnesium alloy-temper for extruded products registered with specified corrosion testing requirements. If additional high magnesium alloy-tempers with similar corrosion testing requirements are registered in the future, they could be added to this specification.
