The main difference between aluminum pipe and aluminum tube is the way it's measured, and the type of application it's used for. A pipe is usually measured using the inside diameter measurement, whereas a tube is measured using the outside diameter measurement.
Aluminum Tube Grades
At Aerotech Alloys, we stock three main grades of aluminum tube:
- 2024 - A high-strength alloy commonly used in aerospace applications. Its yield strength is approximately 10% higher than that of 6061 aluminum, and its ultimate strength is almost 50% higher.
- 6061 - This a medium-strength alloy ideal for every day applications. It is easier to weld, and has a higher resistance to corrosion than 2024 aluminum.
- 7075 - This zinc and copper alloy is stronger than most mild steels. It has good corrosion and fatigue resistance but, although it has average machinability, it is not generally considered weldable.
Aluminum Tube Uses
Tubing can be round, square or rectangular and is used in a huge variety of industries, from furniture components to machine parts, and everything in between.
- 2024 Aluminum tube is often used in structural applications, such as motor sports and the aircraft industry, or anywhere where a high strength-to-weight ratio is required. It is often used for bolts, wheels, gears and shafts because it is non magnetic and heat-treatable.
- 6061 Aluminum tube is commonly found in structural applications as it has a high resistance to stress cracking. It is also non-magnetic and above average corrosion resistance. It has good machinability and is excellent for welding.
- 7075 Aluminum tube - 7075 is a zinc and copper alloy very popular in the aerospace industry due it its superior strength, but lightweight construction.
