5086 Aluminum Tube Material Composition
5086 Aluminum Alloy Composition:
- Magnesium (Mg): 3.5%–4.5%
- Manganese (Mn): 0.20%–0.70%
- Chromium (Cr): 0.05%–0.25%
- Iron (Fe): Max 0.5%
- Silicon (Si): Max 0.4%
- Copper (Cu): Max 0.1%
- Zinc (Zn): Max 0.25%
- Titanium (Ti): Max 0.15%
This composition offers excellent corrosion resistance, especially in marine environments, and helps improve its strength and weldability.
5086 Aluminum Tube Mechanical Properties
5086 Aluminum Alloy has the following properties:
- Tensile Strength: 270–305 MPa (dependent on temper)
- Yield Strength: 125–240 MPa
- Elongation: 10–22% (in 50 mm)
These characteristics make it suitable for applications that require high strength and durability.
5086 Aluminum Tube Physical Properties
- Density of approximately 2.72g/cm³, combining lightweight and high strength characteristics
- Good thermal and electrical conductivity, but it cannot be strengthened through heat treatment; performance must be adjusted via cold working or annealing
5086 Aluminum Tube Tempers
Common tempers include:
- 5086 H32: Strain hardened and stabilized (moderate strength).
- 5086 H116/H321: Optimized for corrosion resistance in marine environments.
5086 Aluminum Tube Corrosion Resistance
- Excellent resistance to seawater, atmospheric, and chemical corrosion.
- Performs better than 5052 in marine environments; comparable to 5083, but with slightly lower strength.
5086 Aluminum Tube Manufacturing and Welding
5086 Aluminum Alloy cannot be heat-treated; instead, strength is gained through strain hardening. It is easily welded using traditional methods such as MIG and TIG. Welding slightly reduces its strength, but it is still suitable for structural applications.
- Manufactured by extrusion (seamless or welded).
- Diameter range: 10 mm to 500 mm, wall thickness: 1 mm to 25 mm.
- Surface treatment: polished, anodized, or coated (e.g., powder coating).
- Filler materials: Use 5356 or 5183 alloys for best results.
- Notes: Avoid prolonged exposure to temperatures ≥65°C to prevent sensitization (intergranular corrosion).
5086 Aluminum Tube Applications
Due to its excellent corrosion resistance and strength, 5086 aluminum tube is widely used in:
- Marine Industry: Hulls, ladders, and offshore structures
- Transportation: Aircraft structural components, missile parts, subway light rail carriages, shipbuilding welded parts
- Industrial Piping: Pressure vessels, low-temperature systems, refrigeration units, TV tower supports
- Military: Vehicle armor and structural components
- Construction: Bridges, roofs, and building components
5086 Aluminum Tube Shapes and Availability
5086 aluminum tubes are available in various shapes, including round, square, and rectangular. They are typically offered in Schedule 40 and Schedule 80 specifications, suitable for different pressure requirements.
| Product Type | Images | Description |
| 5086 Aluminum Round Tube |
|
5086 aluminum round tubes are one of the most common aluminum alloy tubes, widely used in shipbuilding, marine environments, and other high-strength structural applications. Their round shape makes them convenient for welding and machining. Common specifications include Schedule 40 and Schedule 80, suitable for different pressure environments. 5086 aluminum round tubes have excellent corrosion resistance and seawater erosion resistance, making them ideal for offshore operations and harsh environmental applications. |
| 5086 Aluminum Square Tube |
|
5086 aluminum square tubes, due to their uniform cross-section and higher structural strength, are commonly used for manufacturing frame structures and industrial support components. They can withstand higher pressures, especially in Schedule 40 and Schedule 80 specifications, offering strong mechanical properties. This square aluminum tube has good corrosion resistance and salt spray resistance, making it suitable for applications requiring high durability, such as ships and marine equipment. |
| 5086 Aluminum Rectangular Tube |
|
5086 aluminum rectangular tubes, with their unique rectangular cross-section design, offer higher load-bearing capacity and better structural adaptability. These tubes are widely used in construction and industrial equipment, especially in structures requiring large surface contact. Rectangular tubes provide more uniform stress distribution. Like other shapes of aluminum tubes, 5086 aluminum rectangular tubes have strong corrosion resistance in Schedule 40 and Schedule 80 specifications, making them suitable for use in marine environments. |
5086 Aluminum Tube Standards
- ASTM: B209 (Sheet/Plate), B241 (Seamless Tube).
- EN: 573-3 (Alloy), 485-2 (Mechanical Properties).
- ISO: 6361 (Forged Products).
5086 Aluminum Tube Advantages and Disadvantages Summary
| Advantages | Disadvantages |
| High strength, lightweight | Corrosion resistance is lower than other 5xxx series alloys (e.g., 5083) |
| Excellent weldability | Machinability requires improvement through heat treatment |
| Good heat and wear resistance | Susceptible to stress corrosion cracking in annealed state |
5086 Aluminum Tube Machining Properties
- Excellent weldability, suitable for TIG, MIG, and other welding processes
- Machining is average; requires heat treatment (e.g., T6 temper) to improve cutting performance
Comparison
- Compared to 5052: Higher strength, better suited for heavy marine applications.
- Compared to 6061: Poorer heat treatment performance, but better corrosion resistance.
