SCOPE The material defined by this specification is a stampable, heat treatable 6xxx series autobody aluminum sheet alloy. 2. APPLICATION This specification was originally released for material used for stamped bo

3、dy panels, particularly where a combination of formability and age hardening at low paint oven temperatures (170 - 180 C) is required. Note: The yield strength of the material after the paint operation depends on the amount of forming deformation and the specific paint bake process. 3. REQUIREMENTS

4、3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 CHEMICAL COMPOSITION (ASTM E 34/ASTM E 101/ASTM E 227/ASTM E 607/ASTM E 1251) The determination of the chemical c

15、07. 3.7 FORMABILITY The quality level of aluminum alloy supplied to fabricate a specific component is to be negotiated between the Manufacturing activity and the aluminum supplier. Acceptance of subsequent orders by the aluminum supplier for a given component at the agreed upon quality level implies

16、 that all aluminum supplied will form that part satisfactorily as defined by the Manufacturing activity. 3.8 SHELF LIFE The material properties given in this specification shall be valid for a period of six months from the date of manufacture (final thermomechanical processing stage). 5. GENERAL INF

17、ORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 INITIAL SUPPLIER APPROVAL For initial approval, the supplier must furnish the following information: . A plan detailing how each requirement of para 3 will be cont

18、rolled on a continuing basis. . Test results from a typical production sample for the requirements outlined in para 3. . Test results from typical production samples for paintability requirements outlined in para 3.5. . Mechanical property histograms including mean and standard deviations values. Da
