  • MANUFACTURING METHOD FOR WIDE-RANGE FINE-GRAINED MAGNESIUM ALLOY THIN-SHEET MATERIAL
    Publication number: 20090136379
    Abstract: A manufacturing method for wide-range fine-grained magnesium alloy thin-sheet material is disclosed. The method includes an extrusion process and a rolling process. By the plastic deformation feature of the two processes, the wide-range fine-grained magnesium alloy thin-sheet material that satisfies the requirement of cases of 3C products with thickness of less than 1 mm is produced. Thus the method overcomes shortcomings of a conventional method that produces the material by a plurality passes of processes. Therefore, the manufacturing cost is reduced and the method is able to be applied to various industries.
