What is Aluminum 1100 Alloy?
Aluminum 1100 is a commercially pure aluminum alloy with a minimum of 99% aluminum content. It gives excellent ductility, thermal and electrical conductivity and corrosion resistance.
When formability and corrosion protection are more critical than mechanical strength, Alloy 1100 is chosen to high-strength aluminum alloys.
Key Benefits of Alloy 1100 Fittings- Excellent corrosion resistance
- Lightweight material
- High thermal conductivity
- Easy welding and fabrication
- Good ductility and machinability
- Smooth surface finish
- Suitable for low-pressure applications
Types of ASTM B361 Aluminum 1100 Pipe Fittings
➤ ASTM B361 Aluminum 1100 Elbow with 45 or 90 Degrees
The elbow fitting is used to change the direction of flow in a piping system. We manufacture both long-radius and short-radius elbows in 45°, 90°, and 180° configurations.
Applications include:
- Chemical transfer lines
- HVAC systems
- Food-grade piping
- Water distribution systems
