What are the differences in between Aluminium 1060, 5052, and 6061 for pipe fittings and flanges?
Aluminium 1060:
Commercially pure aluminium (≥99.6% Al).
Tensile strength: ~70–125 MPa.
Yield strength: ~35–55 MPa.
Excellent ductility and formability, ideal for low-pressure piping systems.
Limited strength, not suitable for high-pressure applications.
Aluminium 5052:
Aluminium-magnesium alloy with moderate strength.
Tensile strength: ~190–240 MPa.
Yield strength: ~90–160 MPa.
Excellent corrosion resistance, especially in marine and chemical environments.
Suitable for medium-pressure piping systems and industrial fittings.
Aluminium 6061:
Aluminium-magnesium-silicon alloy with high strength.
Tensile strength: ~290–310 MPa.
Yield strength: ~240–270 MPa.
Excellent weldability, corrosion resistance, and pressure handling capability.
Ideal for high-pressure piping, structural, and industrial applications.
What are the fabrication considerations for Aluminium 1060 / 5052 / 6061 fittings and flanges?
Welding:
6061 and 5052 are highly weldable using TIG, MIG, and friction stir welding; post-weld strength reduction must be considered for 6061.
1060 has excellent weldability but is limited in high-pressure applications.
Forming:
1060 is highly ductile and easy to form into elbows, tees, and reducers.
5052 has moderate formability, suitable for bends and shaped fittings.
6061 requires heat treatment (T6 temper) and controlled forming due to higher strength.
Machining:
All three alloys are machinable, but 6061 is preferred for precision machined flanges due to dimensional stability.
Are Aluminium 1060 / 5052 / 6061 fittings compatible with other piping materials?
Electrical/galvanic considerations:
Aluminum fittings must be isolated from steel or copper to prevent galvanic corrosion.
Use insulating gaskets, sleeves, or coatings if joining dissimilar metals.
Thermal compatibility:
Aluminium has higher thermal expansion than steel; allowances must be made in pipe design to prevent stress on flanges/fittings.
