6061 6063 5083 5086 6060 Anodised Aluminium Rectangular alloys round Pipe
The advantages of aluminum alloy are lightweight, excellent electrical and thermal conductivity, high corrosion resistance and ductility.
Aluminum alloy is soft and usually alloyed with copper, zinc, magnesium, silicon, manganese and lithium to increase strength. When aluminum alloy is exposed to air, an anti-oxidant coating will be formed instantly to protect products. Aluminum alloy is one of the lightest metals. The application of products ranges from precision technology to daily commodities.

5086 Aluminum Pipe
5086 aluminum pipe is a high strength magnesium alloyed aluminum product primarily used in the marine industry due to its excellent corrosion resistance, especially to seawater. In addition to good corrosion resistance, this alloy also has good weldability characteristics.
6061 Aluminum Pipe
6061 aluminum pipe is a magnesium and silicon alloyed aluminum material. This good all-purpose alloy has good corrosion resistance and formability and has medium strength. It has good machining characteristics and has excellent appearance after anodizing.
6063 Aluminum Pipe
6063 aluminum pipe is made from a popular heat treatable magnesium/silicon alloy. This alloy has excellent corrosion resistance and weldability. Due to its finer grain structure, this is an excellent alloy choice for anodizing. Applications include air cylinder, electrical bus conductor and architectural.
5083 Aluminum Pipe
This magnesium alloyed aluminum product is primarily used in the marine industry due to its excellent corrosion resistance, especially to seawater. In addition to good corrosion resistance, 5083 aluminum pipe also has good weldability characteristics for fabricating vessels.
This product listing covers aluminum round hollow sections (pipe/tube) made from four distinct alloys: 3003, 5083, 6061, and 7075. The choice of alloy is critical, as it determines the material’s strength, corrosion resistance, weldability, and typical use cases.
1. Breakdown by Aluminum Alloy
The 4-digit number is an international designation system for aluminum alloys. The first digit indicates the primary alloying element.
3003 Aluminum (Good Formability & General Purpose)
-
Alloy Series: 3xxx series (Manganese is the principal alloying element).
-
Key Properties: Moderate strength, excellent corrosion resistance, very good formability and workability. It is the most common general-purpose aluminum alloy. It is non-heat-treatable; its strength comes from strain hardening.
-
Common Uses:
-
General fabrication
-
Chemical equipment
-
Decorative trim
-
HVAC systems
-
Storage tanks
-
5083 Aluminum (Marine & High-Strength Welded Structures)
-
Alloy Series: 5xxx series (Magnesium is the principal alloying element).
-
Key Properties: Excellent strength for a non-heat-treatable alloy, and outstanding corrosion resistance, especially in marine environments (seawater). It has excellent weldability and retains high strength after welding.
-
Common Uses:
-
Marine applications (boat hulls, superstructures)
-
Offshore platforms
-
Pressure vessels
-
Military vehicles
-
Cryogenic applications
-
6061 Aluminum (The Most Versatile Structural Alloy)
-
Alloy Series: 6xxx series (Magnesium and Silicon as primary elements).
-
Key Properties: A heat-treatable alloy with good strength, excellent corrosion resistance, and superb machinability. It is highly versatile and weldable. It is often supplied in the T6 temper (solution heat-treated and artificially aged) for maximum strength.
-
Common Uses:
-
Structural frameworks and welded assemblies
-
Aerospace components
-
Automotive parts (chassis, frames)
-
Bicycle frames
-
Marine fittings
-
General high-strength pipes and tubes
-
7075 Aluminum (Aerospace-Grade High Strength)
-
Alloy Series: 7xxx series (Zinc is the principal alloying element).
-
Key Properties: One of the highest strength aluminum alloys available. It is heat-treatable and has a strength-to-weight ratio comparable to many steels. Its drawbacks are poor corrosion resistance compared to other alloys (often used with cladding for protection) and very poor weldability. It is primarily joined by riveting or bonding.
-
Common Uses:
-
Aerospace structures (aircraft wings/fuselages)
-
High-performance bicycle components
-
Mold tools and jigs
-
Rock climbing gear
-
Critical high-stress structural parts
-
2. Product Form: Aluminum Round Pipe / Tube
The terms “pipe” and “tube” are often used interchangeably, but there is a technical distinction:
-
Pipe: Typically defined by its Nominal Pipe Size (NPS) and schedule (wall thickness), used for transporting fluids.
-
Tube: More precisely defined by its outside diameter (OD) and wall thickness, used for structural and mechanical applications.
Given the alloys listed (especially 6061 and 7075), this product is likely round tube intended for structural and mechanical applications.
Alloy Selection Guide
| Alloy | Primary Strength | Corrosion Resistance | Weldability | Machinability | Best For |
|---|---|---|---|---|---|
| 3003 | Low-Medium | Excellent | Good | Good | General purpose, ductile parts, chemical exposure |
| 5083 | High (Non-HT) | Exceptional (Marine) | Excellent | Fair | Marine, offshore, welded structures |
| 6061 | High (Heat-Treated) | Very Good | Excellent | Excellent | Structural frames, automotive, bikes, general high-strength |
| 7075 | Very High (Aerospace) | Poor | Poor | Good | Aerospace, high-performance racing, non-welded parts |
HT = Heat-Treatable
How to Choose the Right Alloy for Your Project
-
Is it a welded structure?
-
YES: Choose 6061 (best all-around) or 5083 (for marine or highest as-welded strength). Avoid 7075 for welding.
-
NO: All options are open.
-
-
What is the operating environment?
-
Marine or harsh chemical: 5083 is the premier choice. 3003 and 6061 are also very good.
-
General outdoors/industrial: 6061 or 3003.
-
-
What is the primary requirement?
-
Maximum Strength & Stiffness: 7075 is the clear winner, provided you don’t need to weld it and can manage its corrosion susceptibility.
-
Best All-Round Performance (Strength, Weldability, Corrosion): 6061 is the most versatile and widely used choice.
-
Formability and Ductility: 3003 is easiest to bend and shape.
-
Strength in a Marine Welded Structure: 5083 is unmatched in this category.
-
In summary, this listing provides options from a general-purpose alloy (3003) to a specialized marine alloy (5083), a versatile structural alloy (6061), and a super-strong aerospace alloy (7075). Your application’s need for strength, weldability, and corrosion resistance will determine the best choice.
