# 5754-H26 Aluminum Alloy Technical Datasheet ## Material Overview 5754-H26 is a strain-hardened temper variant of the 5754 aluminum-magnesium alloy, offering high strength characteristics while maintaining adequate formability. The H26 temper indicates that the material has been strain-hardened beyond the half-hard condition but not quite to the full-hard state, then stabilized to ensure property consistency. This temper provides enhanced mechanical performance for applications requiring substantial strength in structural and marine environments. --- ## 1.
