4015-O Aluminum alloy,Aluminum 4015-O alloy,E FORU

### **Product Introduction: Aluminum 4015-O Alloy** **Overview** Aluminum 4015-O Alloy is a non-heat-treatable aluminum-silicon alloy supplied in the annealed (O) temper condition. This temper represents the softest state of the material, providing maximum ductility and formability while maintaining good corrosion resistance and electrical conductivity. The "O" temper makes it particularly suitable for applications requiring severe forming operations, deep drawing, and complex shaping processes. --- ### **1.
