Common Materials

6061 ALUMINUM SHEET

This is the most versatile of the heat treatable aluminum alloys. It has most of the good qualities of aluminum, and it offers a wide range of mechanical properties and corrosion resistance. It can be fabricated by many of the commonly used techniques. In the annealed condition, it has good formability. In the T4 condition, fairly severe forming operations may be accomplished. The T6 properties may be obtained by artificial aging. It is welded by all methods and can be furnace brazed.

American Specifications:   ASTM B209, AMS 4025, AMS 4026, AMS 4027, MIL-F-17132, QQ-A-250/11

British Specifications:   H20, HE 20

Applications:   This grade is used for a wide variety of products and applications from truck bodies and frames to screw machine parts and structural components. Alclad 6061 is used where appearance and better corrosion resistance with good strength are required.
