All of the alloys, tempers and product forms covered in the Aluminum Association “Aluminum Standards and Data” (ASD) Manual are a p
12、art of and will be specified through CEMS C-10. The ASD manual contains detailed information on standard wrought alloys and the mill products normally produced from these alloys.

For informational purposes, CEMS C-10 Appendix also prov
14、ides typical mechanical properties in Table A-III(a) and variation of tensile properties with temperature in Table A-III(b) (Appendix). 6.3 Permissible Alternates When a particular type of aluminum alloy is specified on a drawing, it may be desirable or advantageous to permit the manufacturing plant
15、 or supplier to use an alternate aluminum alloy. Permissible alternates for certain specific aluminum alloys are described in this section. The manufacturer/supplier is responsible to ensure that the alternate alloy selected has adequate formability, weldability, surface quality or other necessary p
16、roperties to successfully fabricate the part. 6.3.1 AA 6005/6105 When alloy 6005 or 6105 is specified on a drawing, the use of either alloy is optional. 6.3.2 AA 2008-T4/6022-T4 When alloy 2008-T4 or 6022-T4 is specified on a drawing, the use of either alloy is optional. Note that there may be sligh
17、t differences in formability in some manufacturing processes. 6.3.3 AA 6005-T5/6061-T6/6351-T5 When alloy 6005-T5 or 6061-T6 or 6351-T5 is specified on a drawing, the use of any one of these alloys and tempers is optional. 6.3.4 AA 6463/6463A When alloy 6463 is specified on a drawing, alloy 6463A ma
18、y be substituted. 6.4 Surface Finishes All materials will be supplied in the mill finish unless otherwise specified. If another mechanical or chemical surface finish is desired (e.g., M21 for high gloss mechanical polish), the finish should be specified on the engineering drawing using the standard

21、r exposed applications, aluminum parts may require anodizing to enhance corrosion resistance (or prevent galvanic corrosion), wear resistance, or for decorative purposes. Generally, anodizing is more cost effective than chrome plating of aluminum. Refer to CEMS G-21 for anodizing requirements. 6.5 P
22、referred Sheet/Plate Thicknesses and Tolerances Refer to Table IV for preferred aluminum thicknesses and Table V for thickness tolerances. Values given in Table IV should be used on engineering drawings when specifying such aluminum products. 6.6 Aluminum Tubing Mechanical properties for aluminum tu
23、bing are included in Table II. Also see Section A.7 in CEMS C-10 Appendix for more information on tubing. Tubing tolerances are dependent on type of aluminum alloy used, type of tube process, and size; refer to the ASD Manual or contact Materials Engineering for more information. 7.0 QUALITYMaterial

25、PROVAL AND QUALITY CONTROL9.1 Supplier RequirementsAll suppliers to NAVISTAR are required to be registered to ISO 9001 Quality System Requirements. NAVISTAR will also accept TS-16949 registration as long as the supplier can also fulfill all AIAG PPAP (Production Part Approval Process) documentation
26、and approval requirements. Suppliers must maintain their certification with an accredited registrar and must furnish copies of registration certificates to their Corporate Buyer upon request. 9.2 ApprovalParts supplied against contracts or purchase orders citing this specification shall be equivalen
27、t in all respects to those samples which were approved by the purchaser. No changes in formulation or processing practices are permitted without approval. In the event that changes in material, properties, processing practices, construction, color, or labeling of the product are required, the suppli
28、er shall notify Materials Engineering, TDTC Fort Wayne, and Purchasing and Supplier Development of the proposed change(s). Test data indicating conformance to all requirements of this specification, test samples, and new or amended or updated Material Safety Data Sheet(s) (MSDS), in accordance with
