Aluminum Rectangle Bar

Aluminum Rectangle Bar is a widely used aluminum material in various manufacturing and engineering projects, known for its lightweight, corrosion resistance, and ease of processing. Aluminum rectangle bars are typically extruded from aluminum alloys and have a flat surface with square corners, making them easy to weld, cut, and process for various applications.

HC Aluminum provides high-quality aluminum rectangle bars made from top-grade aluminum alloys, ensuring excellent performance and high-precision dimensions. These bars are widely used in various industries to meet customers' requirements for product performance and size.

Typical Aluminum Rectangle Bar Material Choices

• 6061 Aluminum Alloy: 6061 is a widely used aluminum alloy, especially suitable for manufacturing structural components. It has high strength, good corrosion resistance, and weldability, making it ideal for applications requiring hardness and strength. 6061 aluminum rectangle bars can typically be made up to 3 inches in thickness.
• 6063 Aluminum Alloy: 6063 is a softer, more formable aluminum alloy, typically used for applications requiring good formability and lower strength. It has good surface finishing properties, making it suitable for construction, decoration, and applications where appearance is important. 6063 aluminum rectangle bars are generally no thicker than 1/2 inch.

Below is a comparison table between 6061 Aluminum Rectangle Bar and 6063 Aluminum Rectangle Bar:

Aluminum Rectangle Bar Sizes

The size of aluminum rectangle bars can typically be customized based on application needs, including width, thickness, and length. HC Aluminum provides a range of standard sizes, as well as custom-cut lengths according to customer specifications.

Common sizes range from widths of 1 inch to 12 inches, with thicknesses ranging from 1/8 inch to 3 inches. Larger sizes can be achieved through multi-stage forming processes.

Aluminum Rectangle Bar Features

Lightweight

Aluminum rectangle bars are much lighter than traditional materials like steel, offering a significant weight advantage. This makes them widely used in aerospace, transportation, construction, and other industries, particularly for weight-sensitive projects.

Corrosion Resistance

The natural oxide film on aluminum provides excellent corrosion resistance, especially in marine environments and humid climates, where its performance is particularly strong. Both 6061 and 6063 alloys have good corrosion resistance, making them suitable for use in marine, chemical, and exterior structural components.

Machinability

6061 aluminum alloy has good machinability and can be milled, drilled, cut, bent, and welded in various ways, making it suitable for precision industrial machining needs.

6063 aluminum alloy is relatively softer and has good formability, making it ideal for deep extrusion and processing complex shapes, especially in the construction and decoration industries.

Surface Treatment

The surface of aluminum rectangle bars can be anodized to enhance corrosion resistance and surface hardness, while also providing a variety of colors (such as silver, black, gold, etc.). Additionally, spraying, sanding, and coating processes can be applied to improve appearance and protective properties.
