Detailed Description of Aluminum Tubes
Aluminum tubing is made by forcing a heated aluminum billet through a form or die in order to create some common or exact cross-section shape. This extrusion method allows for complex shapes and accurate profiles.
The two most common alloys are 6063, which is available with an excellent surface finish and is ideal for anodized finishes (making it an excellent choice for architectural applications), and 6061, which has more structural strength than 6063.
The primary benefit of aluminum is the natural passive aluminum oxide layer, which forms on its surface when exposed to air and then stops oxidizing further and provides a corrosion resistant layer to aluminum. This is why aluminum is very durable in variety of environments without the need for coatings.
