What are ASTM B247 Aluminum 6061-T6 Flanges?
ASTM B247 6061 Aluminum Flanges are forged or machined pipe flanges manufactured from heat-treated Aluminum Alloy 6061-T6. This alloy contains magnesium and silicon as its primary alloying elements, giving it excellent corrosion resistance, moderate-to-high strength, and excellent weldability.
Compared to many carbon steel flanges, ASME SB247 Aluminum 6061-T6 Flanges are significantly lighter while maintaining excellent structural integrity. Their resistance to atmospheric corrosion and seawater makes them suitable for demanding industrial environments.
These flanges are widely installed in:
- Aerospace equipment
- Marine piping systems
- Chemical processing plants
- Food processing industries
- Water treatment facilities
- Oil & gas support systems
- Structural fabrication
- Automotive industries
- Renewable energy projects
Features of ASTM B247 6061-T6 Forged Flanges
Our Al 6061-T6 Forged Flanges are preferred across industries because they offer:
- Excellent corrosion resistance
- High strength-to-weight ratio
- Outstanding machinability
- Good weldability
- Long service life
- Excellent fatigue resistance
- Non-magnetic properties
- Easy fabrication
- Good thermal conductivity
- Attractive surface finish
- Low maintenance requirements
These features make ASTM B247 6061-T6 Forged Flanges an excellent alternative to heavier stainless steel components in many applications.
