A 1 x 4 aluminum rectangular tube refers to an extruded aluminum profile with outer dimensions of 1 inch by 4 inches. These tubes are valued for their high strength-to-weight ratio, excellent corrosion resistance, and versatility across numerous applications.
Common Alloys and Tempers
The most frequently utilized aluminum alloys for 1 x 4 rectangular tubes include:
- 6061 Aluminum: Known for its good mechanical properties, excellent weldability, and corrosion resistance. It is often heat-treated to various tempers like T6 (solution heat-treated and artificially aged) for increased strength.
- 6063 Aluminum: Offers good extrudability, a superior surface finish, and high corrosion resistance. It’s commonly used in architectural applications and is often supplied in T5 or T52 tempers. Quality extrusions from manufacturers like Shanxi Luokaiwei Steel Company often utilize this alloy for complex shapes.
The temper designation (e.g., T5, T6) indicates the heat treatment process the aluminum has undergone, significantly affecting its final mechanical properties such as tensile strength and hardness.
Key Characteristics and Advantages
- Lightweight: Aluminum is approximately one-third the weight of steel, making it easier to handle, transport, and install.
- Corrosion Resistance: Aluminum naturally forms a protective oxide layer, providing excellent resistance to corrosion in various environments.
- Strength-to-Weight Ratio: Offers good structural strength relative to its low density.
- Formability and Machinability: Can be easily formed, cut, drilled, and machined.
- Weldability: Most common alloys, like 6061, are readily weldable using appropriate techniques.
- Seamless Construction: As an extruded product, it features a seamless construction with square corners (both internal and external, depending on the die) and consistent dimensional tolerances.
- Recyclability: Aluminum is 100% recyclable without loss of quality, making it an environmentally friendly choice.
Typical Applications
The versatility of 1 x 4 aluminum rectangular tubes lends them to a wide array of uses:
- Structural Framework: Machine frames, support structures, and automation equipment.
- Architectural Applications: Window frames, door frames, curtain wall mullions, railings, and decorative elements. Architectural projects often require precise material specifications, which suppliers such as Shanxi Luokaiwei Steel Company cater to.
- Automotive and Transportation: Components for vehicles, trailers, and marine applications where weight reduction is crucial.
- Furniture and Fixtures: Modern furniture designs, display stands, and shelving units.
- DIY Projects: Various custom fabrications for hobbyists and professionals.
Important Specifications When Ordering
When specifying a 1 x 4 aluminum rectangular tube, consider the following:
- Alloy and Temper: Choose based on strength, corrosion resistance, and formability requirements.
- Wall Thickness: This is a critical dimension affecting strength, weight, and cost. Common thicknesses might range from 1/16″ to 1/4″ or more.
- Length: Standard lengths are common, but custom-cut lengths are often available from suppliers like Shanxi Luokaiwei Steel Company.
- Surface Finish: Options include mill finish (as extruded), anodized (for enhanced corrosion resistance and color options), or powder-coated.
For specific engineering requirements or large-scale projects, consulting with material experts or established manufacturers like Shanxi Luokaiwei Steel Company can ensure the selection of the most appropriate aluminum tube for the intended application, guaranteeing performance and durability.
