5086 Aluminum Drawn Seamless Pipe Chemical Composition
5086 aluminum is primarily alloyed with magnesium, which gives it strength and corrosion resistance. Unlike some aluminum alloys, 5086 is strengthened not by heat treatment but by strain hardening or cold mechanical processing. This property allows it to retain much of its mechanical strength even after welding.
- Major Components: Aluminum (balance), Magnesium (3.5%-4.5%), Manganese (0.2%-0.7%), Chromium (0.05%-0.25%).
- Other Elements: Iron ≤0.5%, Silicon ≤0.4%, Zinc ≤0.25%.
5086 Aluminum Drawn Seamless Pipe Physical Properties
- Density: 2.66 g/cm³.
- Conductivity: Suitable for electrical conductivity applications.
5086 Aluminum Drawn Seamless Pipe Mechanical Properties
- Yield Strength: Approximately 28.3 ksi (195 MPa) in H32 temper.
- Ultimate Tensile Strength: Approximately 30.1 ksi (207 MPa) in H32 temper.
- Elongation: Elongation ranges from 6% to 12% in H32 temper.
5086 Aluminum Drawn Seamless Pipe Characteristics
Mechanical Strength:
- Tensile Strength: 210-300 MPa (H32 temper).
- Yield Strength: 28, 000-44, 000 psi.
- Strengthened through strain hardening (cold working) instead of heat treatment, maintaining weldability.
Corrosion Resistance:
- Excellent seawater resistance, making it an ideal choice for marine applications (e.g., hulls, offshore platforms).
- Superior stress corrosion cracking resistance compared to alloys like 5052 and 5083.
Weldability:
Compatible with TIG, MIG, and arc welding methods. Arc welding is recommended for optimal results.
5086 Aluminum Drawn Seamless Pipe Applications
- Marine Industry: Shipbuilding, gangways, and seawater transport systems.
- Automotive: Used for welded structural components and lightweight body parts.
- Power Equipment: Used as conductive piping in power transmission systems.
- Pressure Vessels: Refrigeration units, missile components, and other fire-resistant applications.
- Construction & Machinery: Structural support for television towers and exploration equipment.
- Industrial Use: Pressure vessels, storage tanks, military vehicles, and cryogenic equipment.
- Infrastructure: Aerospace components, rail vehicles, and structural frames.
5086 Aluminum Drawn Seamless Pipe Manufacturing Process
| Item | Description |
| Hot Extrusion | Manufactured using seamless extrusion technology to create the base pipe billet, with common temper as H112. |
| Drawing Process | Cold drawing process improves dimensional accuracy and surface quality, meeting special section requirements (such as square pipes, flat tubes, etc.). |
Production Methods:
- Extrusion: Hot extrusion shapes the seamless tube using molds.
- Cold Drawing: Final dimensioning through cold drawing enhances dimensional accuracy and surface finish.
- Temper: Available in H32 (work-hardened and stabilized) and H111 (partially work-hardened) states.
Advantages Compared to Competing Alloys
- Higher strength-to-weight ratio compared to 5052 and 5083 alloys.
- More cost-effective due to reduced need for post-weld treatments.
Limitations and Precautions
- Avoid prolonged exposure to high temperatures to prevent softening.
- Use lubricants during processing to reduce friction and surface damage.
5086 Aluminum Drawn Seamless Pipe is a versatile, high-strength solution suitable for corrosive and high-pressure environments. Its weldability, custom options, and compliance with international standards make it the preferred choice in marine, industrial, and military sectors.
