What Is an Aluminum Rectangle Bar?

An aluminum rectangle bar is a solid, flat-sided bar with a rectangular cross-section, produced through extrusion or rolling processes. It is commonly used when high strength, low weight, and easy fabrication are required.
Depending on customer needs, aluminum rectangle bars can be produced in various widths, thicknesses, lengths, alloys and temper grades.

Common Alloys Used

2024 Aluminum Alloy

2024 aluminum is one of the strongest alloys in the 2xxx series due to its high copper content. It is well known for its excellent fatigue resistance, which makes it a preferred alloy for aerospace components and high-performance mechanical parts. The alloy offers a very high strength-to-weight ratio, making it a perfect replacement for steel in applications where weight reduction is critical.

Another important characteristic of 2024 aluminum is its outstanding machinability. It can be easily milled, drilled, and formed into complex shapes. However, compared to other alloys, its corrosion resistance is lower, especially in moist or marine environments. For this reason, 2024 aluminum is often used with protective coatings, cladding, or anodizing when exposed to harsh conditions.

In flat bar form, 2024 aluminum provides excellent rigidity and dimensional stability. This makes it ideal for aircraft fittings, structural frames, fasteners, and precision machined components where both strength and fatigue performance are essential.

5083 Aluminum Alloy

5083 aluminum is the strongest non-heat-treatable alloy in the 5xxx series, known for its exceptional corrosion resistance, especially in marine environments. The presence of magnesium as the primary alloying element gives it outstanding resistance against seawater, chemicals, and industrial atmospheres. This is why 5083 aluminum is widely used in shipbuilding, offshore platforms, and watercraft structures.

In addition to corrosion resistance, 5083 aluminum offers excellent weldability. Welding does not significantly reduce its strength, making it suitable for applications requiring large welded structures. Its mechanical properties remain stable even at cryogenic temperatures, which is an important advantage for LNG tanks and cold storage equipment.

As a flat bar, 5083 aluminum performs exceptionally well in load-bearing, structural, and corrosive environments. It is commonly used for marine frames, pressure vessels, vehicle armor, and transportation equipment where durability and resistance to harsh conditions are essential.

6061 Aluminum Alloy

6061 aluminum is the most versatile and widely used alloy in the 6xxx series due to its balanced combination of strength, corrosion resistance, weldability, and machinability. It is a heat-treatable alloy that achieves excellent mechanical performance in the T6 temper, making it suitable for a wide range of structural and engineering components.

One of the most significant advantages of 6061 aluminum is its weldability. Welding does not severely compromise its properties, unlike many high-strength alloys. Its corrosion resistance is also impressive, allowing it to perform well outdoors, in industrial environments, and in transportation applications. Its machinability is excellent, making it a popular choice for precise and detailed machining processes.

In flat bar form, 6061 aluminum is used in construction, machinery, vehicle frames, industrial components, and general-purpose structures. Its combination of mechanical strength, weight savings, and cost-effectiveness makes it one of the most common alloys for aluminum bars and extrusions.

7075 Aluminum Alloy

7075 aluminum is one of the highest-strength aluminum alloys available, comparable to many steels but significantly lighter in weight. This alloy is dominated by zinc as its primary alloying element, resulting in exceptional tensile strength, fatigue strength, and toughness. It is widely used in aerospace, defense, motorsports, and applications where maximum performance is required.

Despite its remarkable strength, 7075 aluminum has lower corrosion resistance than alloys such as 5083 or 6061. However, with anodizing or protective coatings, it can perform well even in demanding environments. It is also less weldable than other alloys, making it more suitable for machined parts rather than welded structures.

7075 aluminum flat bars are commonly used in aircraft components, high-performance gears, drive shafts, tooling, and precision mechanical parts. They are ideal for applications where every gram of weight matters while maintaining maximum structural integrity.
