Tube
Kaiser Aluminum is a world class leader in drawn seamless, extruded seamless, and extruded structural aluminum tubing especially tailored for general engineering applications. Seamless and drawn seamless tube can be created from the following alloy selections: 1100, 2024, 3003, 5052, 6061, 6063, 7050, 7075. Extruded structural tubing can be produced from the following alloys: 6061, 6063.
1100
The purest of the aluminum alloys. This alloy is typically used in applications requiring maximum ductility and relatively low strength. Good corrosion resistance, workability and weldability.
2024
This alloy is heavily utilized in aircraft applications because it has good machining characteristics and higher strength than either 2014 and 2017. Though cold formability is considered fair, it is one of the most popular alloys for cold heading and thread rolling applications as a result of the superior grain structure that can be obtained. Corrosion resistance and anodizeablilty are only fair. It is also the basic alloy for cold finished square and rectangular bar. Again, this is because of its high strength and good machinability, which are essential for precision fittings and parts.
3003
One of the Manganese alloys. Typically used for condensers and heat exchangers in chemical equipment and pressure vessels. Good corrosion resistance, workability and weldability.
5052
One of the Magnesium alloys. Typically used in hydraulic tube and appliance applications. Good corrosion resistance and good weldability.
6061
Generally selected where welding or brazing is required or for its high corrosion resistance in all tempers. Formability is excellent in O temper and good in the T4 temper. Machining is more difficult when compared to the other machining alloys. Corrosion resistance and appearance after anodizing are superior.
6063
Magnesium/Silicon alloy. One of the most popular of the Heat Treatable alloy group. Products include Extruded and Drawn Tube, Pipe, Rod, Bar and Profiles. Good corrosion resistance, good weldability and good anodizing response.
7050
This alloy is used in aircraft structural parts. The alloy has characteristics of high strength coupled with good resistance to exfoliation and stress corrosion cracking. The alloy also has good fracture toughness and fatigue resistance.
7075
This alloy offers the highest strength of the common screw machine alloys. The superior stress corrosion resistance of the T173 and T7351 tempers makes it a logical replacement for 2024, 2014 and 2017 in many of the most critical applications. The T6 and T651 tempers have fair machinability, resistance welding and corrosion resistance ratings. This alloy is heavily utilized by the aircraft and ordnance industries because of its superior strength.
