What is Aluminum Flat Bar

What is aluminum flat bar？

aluminum flat bar is a solid, rectangular piece of aluminum that is widely used in construction, fabrication, and various industrial applications. It’s available in different sizes, thicknesses, and alloy grades, making it versatile for a wide range of uses. Here’s a detailed overview:

 

Features of Aluminum Flat Bars

1. Material Composition:
   • Typically made from aluminum alloys such as 6061, 6063, or 7075, which offer a balance of strength, corrosion resistance, and machinability.
   • Common grades:
     • 6061 Aluminum: Known for its strength, weldability, and corrosion resistance. Suitable for structural components.
     • 6063 Aluminum: Often used for architectural applications due to its smooth surface finish and excellent corrosion resistance.
     • 7075 Aluminum: High strength, used in aerospace and heavy-duty applications, though less corrosion-resistant.

 

Comparison of Alloy Types for Aluminum Flat Bars:

Alloy Type	Strength	Corrosion Resistance	Machinability	Weldability	Common Application
6061	High	Good	Excellent	Excellent	Structural components, machinery, frames
6063	Moderate	Excellent	Good	Excellent	Architectural, railings, furniture
7075	Very High	Fair	Moderate	Poor	Aerospace, high-performance parts

 

           2.Surface Finish:

The finish or surface treatment of aluminum flat bars can vary depending on the intended application and desired appearance.

• Mill Finish Aluminum Flat Bar
• Anodized Aluminum Flat Bar
• Brushed Aluminum Flat Bar
• Powder-Coated Aluminum Flat Bar

 

 

General Dimensions

1. Thickness: Aluminum flat bars usually range from 0.2mm to 8.0mm.
2. Width: The width ranges widely from 20mm to 600mm.
3. length: length range is usually from 1000mm to 6000mm, customized as needed.

Common specifications

• 1.0mm × 20mm × 2000mm
• 1.0mm × 30mm × 2000mm
• 1.0mm × 40mm × 2000mm
• 1.0mm × 50mm × 2000mm

These specifications are from Hugh Aluminum. The actual production can be customized according to the specific needs of customers.

 

 

 

 

Advantages of aluminum flat bar:

Corrosion resistance:

Aluminum flat bar will form a dense oxide film on the surface, which can resist most of the chemical corrosion and electrochemical corrosion.
Therefore, aluminum flat bar can maintain good stability in humid, acidic or alkaline environments, prolonging its service life.

Strong plasticity:

It has good plasticity and ductility. It can be processed and molded through various processes such as stretching and bending.
This enables aluminum flat bar to meet a variety of complex shapes and design requirements. It provides designers and manufacturers with more creative space.

Environmentally friendly:

Aluminum is an environmentally friendly material which has good recyclability. The waste produced during the use of the flat bar can be recycled and reused, reducing environmental pollution and resource waste.

Applications of Aluminum Flat Bars

1. Construction and Architecture:
   • Used as support beams, structural frameworks, and reinforcement components.
   • Ideal for decorative elements like trims, railings, and sign frames due to their aesthetic appeal and corrosion resistance.
2. Fabrication and Manufacturing:
   • Frequently used in the creation of brackets, mounting plates, and fixtures.
   • Popular for custom metalwork and prototypes in fabrication shops due to its ease of cutting, bending, and welding.
3. Transportation and Aerospace:
   • Found in automotive and aerospace components, such as engine parts, brackets, and panels, because of their high strength-to-weight ratio.
4. DIY and Home Improvement:
   • Aluminum flat bars are widely used in DIY projects, such as shelving, cabinetry, and furniture.
   • Their lightweight nature makes them easy to handle and work with using common tools.
5. Electrical and Marine Uses:
   • Due to its non-corrosive properties, aluminum flat bars are often used in marine environments and electrical projects where durability in harsh conditions is needed.

 

In Summary:

Aluminum flat bar as a high-quality aluminum alloy material, with its lightweight and high strength, corrosion resistance, easy processing and other characteristics in the construction, machinery manufacturing and other fields have been widely used. With the continuous progress of science and technology, the application prospect of aluminum flat bar will be more broad!
