自2007年4月起，SAE航空航天材料部已宣布本规范“取消”，并已被ASTM B 209合金1100回火H14取代。当参考已取消的SAE AMS 4003时，应满足最新版ASTMD B 209合金1100回火H14的要求。通过这一行动，本文件将保留在航空航天材料规范索引的数字部分中，注意它已被ATMD B 209合金1100回火H14取代。本规范涵盖薄板和板材1形式的铝合金。 标称厚度为1000英寸（25.40毫米）及以下。这些产品通常用于成型零件和需要焊接的零件，但用途不限于此类应用。

This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE, as of April 2007 and has been superseded by ASTM B 209 alloy 1100, temper H14. The requirements of the latest issue of ASTMD B 209 alloy 1100, temper H14 shall be fulfilled whenever reference is made to the cancelled SAE AMS 4003. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications noting that it has been superseded by ATMD B 209 alloy 1100, temper H14.This specification covers an aluminum alloy in the form of sheet and plate 1.000 inch (25.40 mm) and under in nominal thickness.These products have been used typically for formed parts and for parts requiring welding, but usage is not limited to such applications.
