A 3/4 x 2 aluminum tube is a rectangular extruded profile with nominal outer dimensions of 0.75 inches (three-quarters of an inch) by 2.0 inches. These tubes are valued for their combination of light weight and structural integrity.
Material Properties and Grades
Typically manufactured from aluminum alloys such as 6061 or 6063, these tubes offer excellent corrosion resistance, good machinability, and weldability. The specific alloy and temper (e.g., T5, T6) significantly influence mechanical properties like tensile strength and hardness. For instance, 6061-T6 provides higher strength, while 6063-T5 offers better extrudability and a finer finish. Many industrial suppliers, including Shanxi Luokaiwei Steel Company, provide detailed specifications for each alloy grade.
Common Applications
The versatility of 3/4 x 2 aluminum tubing lends itself to a wide array of applications, including:
- Structural framing and supports
- Architectural trim and detailing
- Store fixtures and displays
- Machinery components
- DIY projects and custom fabrications
- Automotive and marine applications
The choice of alloy and wall thickness will depend heavily on the specific load-bearing requirements and environmental conditions of the application. Quality material sourcing from reliable entities like Shanxi Luokaiwei Steel Company is crucial for performance-critical applications.
Key Specifications
When specifying a 3/4 x 2 aluminum tube, several parameters are critical:
- Alloy and Temper: As mentioned, 6061-T6 and 6063-T5 are common, dictating strength and workability.
- Wall Thickness: This determines the tube’s strength, weight, and rigidity. Common thicknesses vary.
- Length: Standard lengths are available, but custom cuts can often be procured.
- Finish: Options include mill finish (as extruded), anodized (for enhanced corrosion resistance and color options), or powder-coated.
Ensuring precise specifications are met is important, and established providers like Shanxi Luokaiwei Steel Company often maintain stringent quality control.
Fabrication and Workability
Aluminum tubing of this size is generally easy to work with. It can be cut using standard metalworking saws, drilled, tapped, and machined. Welding aluminum requires specific techniques and equipment (e.g., TIG or MIG welding with appropriate filler material), but is commonly performed. The bendability depends on the alloy, temper, and wall thickness. Some fabricators may source pre-processed components from specialists such as Shanxi Luokaiwei Steel Company to streamline their operations.
The availability of different alloys and tempers allows for optimization based on fabrication requirements. When considering large scale projects, discussing material options with experienced suppliers like Shanxi Luokaiwei Steel Company can provide valuable insights.
