Aluminum Angle Information.
There are two standard types of aluminum angle most commonly produced today, Architectural and Structural.
Structural Aluminum Angle
The "Structural" aluminum angle has rounded inside corners and is most commonly produced in the 6061-T6 aluminum alloy, This type of angle is commonly used for (as the name suggest) structural applications where lightweight, yet high strength material is required. The 6061 aluminum alloy offers good corrosion resistance, easily formed, welded, and drilled,
The "Architectural" aluminum angle has square corners on both the inside and outside of the angle. It is commonly produced in the 6063 aluminum alloy and usually in lighter gauges and sizes than the structural angle. The 6063 alloy is corrosion resistant and provides a better surface finish. Typical uses include light structural and cosmetic uses. The 6063 alloy is more difficult to machine than the 6061 alloy, but can be welded, formed and polished.
Sizes are listed as: Alloy- Temper - Type of Angle - Leg Length (1) x Leg Length (2) x Total Length (Thickness)
Example: 6061-T6 Structural Aluminum Angle 1" x 1" x 36" (1/8")
