Based on the strength, durability, weight, and other requirements for the large aluminum tubes in their popular applications, certain alloys of aluminum are preferable in the projects. The most common aluminum alloys for large tubes are 6063, 6060, 6061, and 6082. Others are 2024, 7075, and 5052.

Each of these aluminum alloys has unique characteristics that emanate from treatments with magnesium, copper, zinc, manganese, and other metals. 6061 aluminum, for instance, contains magnesium and silicon. These alloying elements make the metal highly corrosion-resistant and easy to weld. That’s part of the reason why this alloy is popular in industrial and structural projects. It is no wonder many large-diameter aluminum tubes are of this grade. This aluminum alloy does an excellent job with truck racks & frames and machine parts.

Then there is 5052 aluminum, which is an alloy containing magnesium. As you would expect, this material is extremely corrosion-resistant. It is so good that it is usable even in brine situations, although it is not the easiest to weld. Projects requiring large aluminum tubes in the chemical and marine environments are fond of this alloy of aluminum.

7075 aluminum is equally relevant in projects where large aluminum tubes are prominent. With its high zinc content, this aluminum alloy presents high strength. It is particularly common in the automotive and aerospace industries, where low weight and superior strength are required.

In some projects, the strength-to-weight ratio is the priority. Aerospace, aircraft, and transportation structural projects are in this category. Provided the environment is not rugged, 2024 aluminum comes in handy. The only possible challenge with the alloy is its relatively poor performance on corrosion resistance. Galvanizing the alloy with the right alloy can ward off rust from 2024 aluminum though.
