Our extensive inventory of Aluminium ASTM B247 5086-H32 Flanges is designed to meet the diverse needs of industries ranging from marine engineering to chemical processing. In this article, we’ll explore the properties, advantages, and applications of these high-quality flanges, ensuring you understand why they are a preferred choice in many demanding environments.
What are ASTM B247 5086-H32 Aluminium Flanges?
ASTM B247 5086-H32 Aluminium Flanges are specialized components made from Aluminium 5086-H32, a high-strength alloy recognized for its excellent corrosion resistance, particularly in marine environments. These flanges are manufactured following the ASTM B247 standard, which specifies the requirements for aluminium and aluminium-alloy forgings. The 5086-H32 alloy designation indicates that the material has been strain-hardened and stabilized, providing enhanced mechanical properties.
These flanges are used to connect pipes, valves, pumps, and other equipment within a piping system, allowing for easy assembly, disassembly, and maintenance. They come in various sizes and pressure ratings to accommodate different system requirements.

Properties of ASTM B247 5086-H32 Aluminium Flanges
The properties of ASTM B247 5086-H32 Aluminium Flanges make them ideal for challenging environments, especially those exposed to corrosive elements. Some of the key properties include:
- High Corrosion Resistance: The 5086-H32 aluminium alloy is known for its outstanding resistance to corrosion, particularly in marine environments. This makes the flanges suitable for applications in seawater and other aggressive media.
- Excellent Strength-to-Weight Ratio: Aluminium 5086-H32 offers a great balance of strength and lightness. The flanges are strong enough to withstand high pressure and stress, yet lightweight, reducing the overall load on the piping system.
- Good Weldability: The alloy’s good weldability allows for easy fabrication and installation of the flanges. It also ensures that the mechanical properties of the flanges are maintained during welding.
- Durability: The strain-hardened and stabilized H32 temper gives these flanges added durability, making them resistant to deformation and wear over time.
- Non-Magnetic: Aluminium 5086-H32 is non-magnetic, making these flanges suitable for applications where magnetic interference must be avoided.
- Low Density: The low density of aluminium reduces the overall weight of the piping system, which is particularly advantageous in aerospace and marine applications.
Advantages of ASTM B247 5086-H32 Aluminium Flanges
Choosing ASTM B247 5086-H32 Aluminium Flanges from Amardeep Steel Centre LLP offers several benefits, including:
- Enhanced Corrosion Resistance: The primary advantage of these flanges is their superior corrosion resistance, which extends the lifespan of the piping system, reduces maintenance costs, and ensures reliable operation in harsh environments.
- Lightweight and Strong: The excellent strength-to-weight ratio of these flanges ensures that they can handle high pressure and loads without adding unnecessary weight to the system. This is especially beneficial in industries where weight reduction is critical.
- Versatility in Applications: The properties of Aluminium 5086-H32 make these flanges versatile, suitable for a wide range of applications, from marine to chemical processing, oil and gas, and even aerospace industries.
- Ease of Fabrication: The good weldability and machinability of the alloy make these flanges easy to fabricate and install, reducing the overall project timeline and costs.
- Cost-Effective Solution: Despite their high performance, ASTM B247 5086-H32 Aluminium Flanges are cost-effective, offering excellent value for money. Their durability and low maintenance requirements further contribute to their cost-effectiveness over the long term.
