Aluminum Angle

For most people that do not work with aluminum angle on a daily basis the details of the different alloys and types of angles available can be confusing. This guide shows the different alloys, types, tolerances and glossary of terms of aluminum angle most commonly available today.

Types 

Architectural Angle - This angle is most commonly produced on 6063 alloy and is commonly used as the name suggest for architectural and cosmetic applications. It is also used for light structural uses. It has square (sharp) corners both inside and out.

 
Structural Angle - Most commonly produced in 6061 alloy, it offers higher strength than architectural angle and is most commonly produced in larger sizes and heavier thicknesses. It has rounded inside radius and round corners on the inside of the legs. The rounded inside provides more material thus increasing the strength even more.
 

 
Alloys:
6063 is an is a medium strength alloy commonly referred to as an architectural alloy. It is normally used in extrusions. It’s main benefits include, excellent finishing qualities, corrosion resistance, anodizes easily, excellent welding, average machining and forming.

6061 is the most commonly used alloys in medium to high strength applications. It can be easily drilled, machined, welded, formed and also offers good corrosion resistance as well as good strength and surface finish. The alloy can be heat treated to attain higher strength. Most commonly found in T6 temper.

Tolerances:

(Tolerances listed are tolerances from listed size of product)

Thickness: (+/- 2%)
Leg Length: (+/-2%)
Length: (+/- .125″)


Glossary of Terms
 Alloy:
Refers to the chemical composition of the material, different materials are added to pure aluminum to give each alloy specific properties that are desired for different applications.

Extruded:
The manufacturing process used to produce dimensional sizes by pushing material through dies to create the sizes desired. Little of no further processing required to achieve the desired size.

Leg:
The dimension of the angle that protrudes in one direction to form 1/2 of the angle.

Thickness or Wall:
Describes the nominal thickness of the material.
