Aluminum Extrusions: The Complete Guide for 2026
Aluminum extrusions are one of the most versatile and cost-effective solutions in modern manufacturing. Whether for construction or aerospace, extruded aluminum profiles offer unmatched strength, lightweight properties, and design flexibility.
What Are Aluminum Extrusions?
Aluminum extrusion is a manufacturing process where aluminum alloy is forced through a die with a specific cross-sectional profile. This results in long, consistent shapes that can be cut to length and further processed via CNC machining.
Unlike cold-finished aluminum, the extrusion process allows for complex hollow and semi-hollow geometries that are impossible with other methods.
Main Types of Extruded Aluminum Profiles
Selecting the right alloy is critical for performance:
- 6061-T6 Aluminum: The most common structural alloy with excellent weldability.
- 6082-T6 Aluminum: Known for high corrosion resistance, ideal for maritime use.
- 7075 Aluminum: Ultra-high strength for aerospace components.
- Precision Extrusions: Profiles with tolerances as tight as ±0.001".
Key Benefits of Using Extrusions
Industries transition to aluminum extrusions because they offer:
- Design Freedom: Complex shapes can incorporate screw slots or snap-fit joints.
- Cost Reduction: Significant savings compared to full CNC machining for long parts.
- Superior Finishing: Ready for anodizing or powder coating.
