4015-H14 Aluminum alloy,Aluminum 4015-H14 alloy,E FORU

### **Product Introduction: Aluminum 4015-H14 Alloy** **Overview** Aluminum 4015-H14 Alloy is a strain-hardened aluminum-silicon alloy in the H14 temper condition, indicating it has been cold worked to achieve a half-hard state. This temper provides an optimal balance between strength and formability, making it suitable for applications requiring moderate strength while maintaining reasonable workability. The H14 condition offers improved mechanical properties over softer tempers while retaining adequate ductility for forming operations. --- ### **1.
