Aluminium Flanges

As a key connecting component in HVAC systems, aluminum flanges are mainly used to realize the connection between pipes and the connection between equipment inlets/outlets and other components, playing an indispensable role.

1. Lightweight​

With a density of ~2.7g/cm³, aluminum is much lighter than steel. Aluminum alloy flange forgings weigh ~40% less than cast iron ones, easing transportation and installation, reducing costs, and lowering pressure on supporting structures.​

2. Reliable Strength​

Aluminum boasts inherent strength, which is significantly enhanced by adding copper, magnesium, or manganese to form alloys and through heat treatment. Yield strength exceeds 200MPa-even 2-3 times that of cast iron flanges-meeting diverse engineering strength needs.​

3. Excellent Corrosion Resistance​

Aluminum reacts quickly with oxygen to form a dense oxide film, acting as a protective shield against further oxidation. This ensures superior performance in corrosive environments (seawater, salt spray, acids, alkalis), extending equipment lifespan.​

4. Good Thermal and Electrical Conductivity​

Aluminum's thermal conductivity is 3-5 times that of cast iron flanges, with strong electrical conductivity. It is widely used in electrical/electronic fields with strict conductivity demands and efficiently dissipates heat in high temperatures to maintain stable equipment operation.​

5. Aesthetic and Easy to Treat​

Aluminum and alloy flanges naturally have a silvery metallic luster. Through oxidation, dyeing, or painting, they can achieve various colors and finishes, satisfying diverse appearance requirements across applications.​

6. Non-magnetic and Non-toxic​

Non-magnetic by nature, aluminum flanges won't disrupt magnetic environments, suiting magnetically sensitive equipment. Being non-toxic, they are ideal for hygiene-critical industries like medical machinery and food processing.​

7. Good Low-temperature Performance​

In low temperatures, aluminum flanges gain strength without becoming brittle, making them an ideal choice for low-temperature devices.​
