5154-H34 Aluminum alloy,Aluminum 5154-H34 alloy,E FORU

### **5154-H34 Aluminum Alloy Product Introduction** **Overview** 5154-H34 is a strain-hardened temper variant of the 5154 aluminum-magnesium alloy that offers enhanced strength characteristics while maintaining good corrosion resistance and moderate formability. The H34 temper indicates the material has been strain-hardened beyond the quarter-hard level (H32) but not quite to the half-hard condition, then stabilized to ensure property consistency. This temper provides an excellent balance for applications requiring higher strength than H32 while retaining adequate formability for fabrication. --- ### **1.
