This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE, as of January, 2008, and has been superseded by SAE AMS 2221. The requirements of the latest issue of SAE AMS 2221 shall be fulfilled whenever reference is made to the cancelled SAE MAM 2221C. 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will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it has been superseded by SAE AMS 2221. This specification covers established metric manufacturing tolerances applicable to bars and rods of copper and copper alloys ordered to metric dimensions. These tolerances apply to all conditions, unless otherwise noted. The term "exclusive" is used to apply only to the higher figure of a specified range. If the tolerance is expressed as a percentage of a specified dimension, the tolerance so calculated shall be rounded to the nearest 0.02 mm to obtain the permissible tolerance. SAE AMS 2221 is the inch/pound version of this MAM.
