5086 H32 Pipe
The term "5086 H32 pipe" refers to a type of aluminum pipe made from alloy 5086 in the H32 temper.
5086 H32 Pipe is a high-strength, corrosion-resistant material primarily used in marine environments and other applications that require high durability and resistance to harsh conditions.
- H Mark: Indicates strain hardening.
- H3: Strain hardened and stabilized (after hardening, it is slightly softened by heat treatment).
- 2: Quarter-hard temper (balanced strain hardening, strength, and ductility).

5086 H32 Pipe Alloy Composition
5086 is an aluminum-magnesium alloy with magnesium as the primary alloying element. This composition gives the material excellent corrosion resistance, especially in seawater environments, as well as medium to high strength.
Series: Belongs to the 5000 series aluminum-magnesium alloy.
Main alloying elements:
- Magnesium (~4%): Improves strength, weldability, and corrosion resistance.
- Manganese (~0.7%): Improves strength and machinability.
5086 H32 Pipe Heat Treatment
5086 cannot be heat treated. Instead, it gains strength through strain hardening or cold mechanical processing, making it suitable for welding with minimal strength loss.
5086 H32 Pipe Mechanical Properties
- Yield strength: Approximately 28.3 ksi (195 MPa)
- Ultimate tensile strength: Approximately 30.1 ksi (207 MPa)
- Elongation: 6-12%
- Hardness: Brinell hardness of about 80 HB
5086 H32 Pipe Characteristics
- Excellent corrosion resistance, especially in marine/saltwater environments.
- Good weldability and formability.
- Medium strength-to-weight ratio.
5086 H32 Pipe Manufacturing and Welding
- Weldability: 5086 aluminum is easily welded using traditional methods such as MIG and TIG. However, welding may reduce its mechanical properties, returning it to the baseline state (O temper).
- Formability: The alloy has good formability, making it suitable for various manufacturing processes.
5086 H32 Pipe Corrosion Resistance
- Marine applications: 5086 aluminum pipes have excellent corrosion resistance in marine environments, making them ideal for hulls, ladders, and other marine structures.
- Other environments: It also performs well in industrial and petrochemical environments.
5086 H32 Pipe Applications
5086 H32 Pipe in Marine Applications
- Shipbuilding industry: Due to its corrosion resistance and strength, it can be used for hulls, ladders, and other marine structures.
- Marine: Shipbuilding, offshore platforms, docks, and railings.
What other industries use 5086 H32 Pipe?
- Pressure vessels: Suitable for manufacturing non-sintered welded pressure vessels.
- Structural components: Used in towers, drilling platforms, and other high-strength, corrosion-resistant structural applications.
- Transportation: Automotive fuel lines, aerospace components, vehicle body structures, containers, etc.
- Industrial: Chemical storage tanks, pressure vessels, and corrosive fluid pipelines.
- Building and machinery: Piping systems, supports, decorative components, and other applications requiring lightweight and corrosion resistance.
5086 H32 Pipe Advantages
- Resistance to stress corrosion cracking.
- Suitable for welding (TIG/MIG) and forming (bending, flaring).
- Lightweight but durable in harsh environments.

Comparison of 5086 H32 Pipe with Similar Alloys
- 5086 vs. 5052: 5086 has a higher magnesium content, offering better strength and seawater resistance.
- H32 vs. H34/H38: H32 is softer than H34 (half-hard) or H38 (full-hard) and has better formability.
This alloy temper combination is ideal for applications requiring corrosion resistance, medium strength, and ease of manufacturing.
5086 H32 Pipe Manufacturing Considerations
- Welding: Use 5356 or 5183 welding wire for optimal results.
- Post-weld treatment: If tempering performance is poor, stabilization treatment can be selected.
- Machining: Due to the softness of aluminum, sharp tools are required; chip removal is crucial.
