1050-O Aluminum alloy,Aluminum 1050-O alloy,E FORU

### **1050-O Aluminum Alloy Product Introduction** **1. Overview** 1050-O is the annealed temper of commercially pure 1050 aluminum alloy, representing the softest and most formable condition in the aluminum temper series. As part of the 1xxx series of non-heat-treatable aluminum alloys, the "O" temper designation indicates the material has been fully annealed to achieve maximum softness and ductility. This temper offers the lowest strength but highest workability among all tempers of 1050 aluminum, making it ideal for applications requiring severe forming and deep drawing operations. **2.
