Aluminum Square Tube

Competitive Metals stocks a large variety of sizes in 6061 and 6063 aluminum square tube. 6061 aluminum square tube offers great strength, weldability and resistance to corrosion; it is ideal for structural applications where rigidity and lightness are paramount. 6063 aluminum square tube is a more formable alloy that offers even greater corrosion resistance but is softer and less strong than that of 6061 aluminum. 

Aluminum Square Tube Features:

• 6061 is the go-to for structural or load-bearing jobs (frames, brackets, marine/auto) where extra toughness matters; 6063 is nicer for intricate extrusions and a finer surface finish, but 6061 wins when you need more strength and durability.
• 6061 applications include automotive, racks, framing, and machined parts. Use 6063 for lighter duty applications that require clean cosmetic extrusions. 
• 6061 Aluminum Square Tube is stocked in 1"x1", 1-1/2"x1-1/2", and 2"x2" sizes with .065 and.125 wall thickness options; other sizes are available as a special order with a quick turnaround. 
• 6063 Aluminum Square Tube is stocked in diameters ranging from ½” x ½” up to 4” x 4” and in wall thicknesses ranging from .062 up to .500.
• Raw mill finish, not polished
