5456-H112 Aluminum alloy,Aluminum 5456-H112 alloy,E FORU

# 5456-H112 Aluminum Alloy Technical Datasheet ## Material Overview 5456-H112 is a strain-hardened temper variant of the 5456 aluminum-magnesium alloy, offering moderate strength combined with excellent corrosion resistance. The H112 temper indicates that the material has been moderately strain-hardened during hot forming processes and is suitable for applications where specific mechanical property requirements are less stringent than fully strain-hardened tempers. This alloy is particularly noted for its excellent performance in marine and structural applications. --- ## 1.
