Abstract:In this paper,the preduction procedure of 8011H18 Aluminiufn alloy is designedby the means of orthogonal method. The production procedure exporiments were made according tothe designed procedure and the mechanical properties were tested. The changes of microstructure inproduction procedure were in vestigated with microscope. The optimal preduction procedure of8011H18 Aluminium alloy is developed,and the anti-theft cap material with fine deep drawing pro-cessabilivand low earing ration has been successfully produced. The earing ratio of the material de-creases from 5%to about 2%and the finished product ratio increases from 86%to about 96%,The mechanism of property improvement and caring ratio reduction of new production procedure has becn also discussed.
