4015-H12 Aluminum alloy,Aluminum 4015-H12 alloy,E FORU

### **Product Introduction: Aluminum 4015-H12 Alloy** **Overview** Aluminum 4015-H12 Alloy is a strain-hardened aluminum-silicon alloy supplied in the H12 temper condition. This temper represents a partially strain-hardened state achieved through cold working, providing a balanced combination of strength and formability. The H12 temper offers approximately one-quarter hard condition, making it suitable for applications requiring moderate strength while maintaining good forming characteristics. --- ### **1.
