SAE International TOLERANCES, METRIC Aluminum Alloy and Magnesium Alloy Extrusions MAM2205

This specification covers established metric manufacturing tolerances applicable to aluminum alloy and magnesium alloy extruded bar, rod, wire, shapes, and tubing ordered to metric 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 general temper designations "-TX510" and "-TX511" are used for brevity and denote the full temper designations -T3510, -T4510, -T6510, -T8510, -T73510, -T76510, -T3511, -T4511, -T6511, -T8511, -T73511, and -T76511, the "X" representing one or more digits preceding the "510" or "511".
