SCOPE The materials defined by these specifications are formable, non-heat treatable 5XXX series (magnesium based) aut
3、obody aluminum sheet alloys. Four distinct variants are identified: A1 consideration should be given to specifying the next lowest minimum gage, e.g. for an existing 0.95 mm nominal gage, the nearest equivalent minimum gage in ES-YC15-1N260-AB is 0.90 mm. Additionally it may be necessary to consult
4、with JFS A 2001 or JFS A 1001, to select a Japanese nominal gauge which satisfies the intent of ES-YC-1N260-AB. 5.4 CROSS REFERENCE OF SPECIFICATIONS (NOTE: FOR GUIDANCE ONLY) Ford Specification TYPICAL ALLOY GRADE (ALSO SEE SAE J454) WSS-M2A163-A1 AA 5754 WSS-M2A163-A2 AA 5754(NG) WSS-M2A163-A3 AA

8、 Drawing shall include, if applicable, the surface quality per ES-F75B-11007-AA, pretreatment per WSS-M10P12-A and forming lubricant (JMS 20.19.10 for Jaguar) e.g. Aluminum, autobody sheet, bare, for a hood inner, would be specified as: WSS-M2A163-A3, Class 2, bare, lubricated (JMS 20.19.10 for Jagu
9、ar) e.g. Aluminum, autobody sheet, bare, for a heat shield, would be specified as: WSS-M2A163-A4, Class 3, bare e.g. Aluminum, autobody sheet, 105MPa., pretreated for adhesive bonding, for a structural member, would be specified as: WSS-M2A163-A2, Class 3, pretreated to WSS-M10P12-A, lubricated (JMS
10、 20.19.10 for Jaguar) e.g. Aluminum, autobody sheet, 85MPa., pre-treated for adhesive bonding, for door opening panel with visible A-post, would be specified as: WSS-M2A163-A1, Class 1, pretreated to WSS-M10P12-A, lubricated (JMS 20.19.10 for Jaguar) Note that A1 & A2 alloys can only be used for applications with limited Class-1 exposure such as door opening panels without an integrated quarter panel. They are not intended for closure panels, fenders, roofs or quarter panels.
