Aluminum Alloy 2024 is a cost-effective material with excellent machinability and a high strength-weight-ratio. In the annealed condition, this alloy is highly workable and can be used in a number of applications, such as fuselage skins for aircrafts, truck wheels, and crew machine products. Its unique composition allows for both hot and cold working, as well as inert gas consumable electrode arc welding. Continental Steel offers this specific alloy in various structural sections.

Aluminum Alloy 7149 is a wrought zinc-aluminum alloy composed of a maximum of 85.9% aluminum, 8.2% zinc, 2.9% magnesium, 1.9% copper, and 0.2% or less of a number of other elements. Aluminum Alloy 7149 is flexible, lightweight, and very durable. An excellent thermal conductor, the material is heat treatable and can be processed hot, and, unlike other aluminum alloys, is virtually rust and corrosion free. These characteristics make Aluminum Alloy 7149 extremely suitable to aerospace and defense applications. Continental Steel & Tube Company offers Aluminum Alloy 7149 in pre-cut sections in a variety of forms.

Frequently used in structural sections, Aluminum Alloy 6061 provides maximum strength and workability. Design engineers utilize 6061 in applications such as construction, architectural components, fittings, and aerospace. Aluminum Alloy 6061 is highly resistant to corrosion, making it a suitable choice for demanding outdoor environments and aerospace applications. It is weldable, brazeable, and can be hot forged — all while maintaining an excellent surface finish.  Aluminum Alloy 6061 is a highly versatile alloy and can be used to build structural elements in virtually any shape or set of dimensions. Continental Steel offers 6061 in structural sections and other forms.

The versatility and workability of Aluminum Alloy 6063 make it an excellent choice for structural section applications. Starting in raw material forms such as tubes, rods, and bars, this alloy can be easily hot- or cold-formed into angles, tees, flat bars, or nearly any other structural section. Aluminum Alloy 6063 can be anodized, allowing for color matching and also giving it greater corrosion resistance. Its excellent aesthetic qualities make it highly sought after for architectural applications like molds and trimming; it is also a top choice for doors and windows.
