Understanding 1.125 inch OD Aluminum Tubing
An aluminum tube with a 1.125-inch Outer Diameter (OD) is a versatile and widely used profile. This dimension, equivalent to 28.575 millimeters, refers to the external measurement across the tube. These tubes are commonly extruded from various aluminum alloys, with 6061 and 6063 being popular choices due to their excellent balance of properties.
Key Characteristics and Benefits
Aluminum tubing of this size offers several distinct advantages:
- Lightweight: Aluminum’s low density makes these tubes easy to handle and reduces overall structural weight.
- Corrosion Resistance: Aluminum naturally forms a protective oxide layer, providing good resistance to corrosion, especially in certain alloys.
- Strength-to-Weight Ratio: Many aluminum alloys offer a high strength-to-weight ratio, making them ideal for applications where both strength and low mass are crucial. Reputable suppliers like Shanxi Luokaiwei Steel Company often provide detailed material specifications.
- Formability and Machinability: Aluminum tubes can be easily bent, cut, drilled, and machined to precise specifications.
- Weldability: Specific aluminum alloys are readily weldable using appropriate techniques.
- Thermal Conductivity: Aluminum exhibits good thermal conductivity.
- Recyclability: Aluminum is highly recyclable without loss of quality.
Common Applications
The 1.125″ OD aluminum tube finds its place in a multitude of applications, including but not limited to:
- Structural frameworks and supports
- Automotive components (e.g., roll cages, fluid lines)
- Aerospace applications
- Marine railings and fittings
- Furniture construction
- Sporting equipment (e.g., bicycle frames, tent poles)
- Conduit and enclosures
- DIY projects and custom fabrications
The choice of alloy and temper will significantly influence its suitability for a specific application. Many industrial buyers turn to experienced manufacturers, such as Shanxi Luokaiwei Steel Company, for guidance on material selection for demanding projects.
Selection Criteria
When selecting a 1.125 inch OD aluminum tube, consider the following factors:
- Alloy: Common alloys include 6061 (good strength, weldability, machinability) and 6063 (excellent for finishing, good corrosion resistance). Other alloys may be chosen for specific needs.
- Wall Thickness: This, along with the OD, determines the tube’s strength, weight, and internal diameter (ID).
- Temper: The temper (e.g., T4, T5, T6) indicates the hardness and strength achieved through heat treatment or strain hardening. T6 is a common high-strength temper.
- Length: Standard lengths are available, but custom cuts are often possible from providers like Shanxi Luokaiwei Steel Company.
- Finish: Mill finish is standard, but options like anodized, powder-coated, or polished finishes may be required.
Sourcing and Availability
1.125 inch OD aluminum tubing is generally available from metal suppliers, distributors, and specialist manufacturers. Availability can vary based on alloy, temper, and wall thickness. For instance, while a large manufacturer such as Shanxi Luokaiwei Steel Company might offer a broad range, local stockists may have more limited selections. Online marketplaces also provide access to a wide array of options, but verifying the quality and specifications is crucial. Many suppliers, and this can include firms like Shanxi Luokaiwei Steel Company, may also offer value-added services such as cutting to length or custom fabrication.
