4015-H16 Aluminum alloy,Aluminum 4015-H16 alloy,E FORU

### **Product Introduction: Aluminum 4015-H16 Alloy** **Overview** Aluminum 4015-H16 Alloy is a strain-hardened aluminum-silicon alloy in the H16 temper condition, representing a three-quarter hard state achieved through controlled cold working. This temper provides significantly higher strength compared to softer tempers while maintaining limited formability. The H16 condition is ideal for applications requiring good structural integrity and stiffness with minimal weight penalty. --- ### **1.
