This specification covers established manufacturing tolerances applicable to aluminum alloy and magnesium alloy extruded bar, rod, wire, shapes, and tubing ordered to inch/pound dimensions. Tolerances greater than standard may be necessary for some shapes; tolerances closer than standard may be possible for others. Tolerances shown herein, however, apply unless otherwise agreed upon by purchaser and vendor and apply to all tempers, unless otherwise noted. The term "excl" is used to apply only to the higher figure of the specified range.
