Aluminum Extruded Flat Bars ASTM B221

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.The T6 properties may be obtained by artificial aging. It is welded by all methods and can be furnace brazed.

Below you will find a comprehensive chart detailing each grade, their applications and size range stocked for FLAT shaped bars.

Description: 6061-T6511 extruded aluminum is generally selected where welding or brazing is required or for its high corrosion resistance in all tempers. Machining is more difficult when compared to the other machining alloys. Corrosion resistance and appearance after anodizing are superior to all other screw machine alloys while strength is the lowest.
Application: This grade is used for a wide variety of products and applications from truck bodies and frames to screw machine parts and structural components.
