Can 7075 Aluminum Be Extruded?

Yes, 7075 aluminum can be extruded, but it demands specialized expertise and precise process control. Renowned for its exceptional strength-to-weight ratio – often surpassing mild steel – 7075 is a premier choice for aerospace, high-performance automotive, and demanding defense applications. However, its very strength presents unique challenges during extrusion.

The Challenge: Strength vs. Extrudability
While common alloys like 6061 extrude relatively easily, 7075's high zinc and copper content significantly increases deformation resistance and reduces hot workability. Key hurdles include:

1. High Pressure Requirements: Demanding significantly greater force than softer alloys.

2. Narrow Thermal Processing Window: Requires precise billet preheating (typically 360-420°C / 680-790°F) and strict temperature control throughout extrusion to prevent cracking.

3. Susceptibility to Surface Defects: Prone to issues like hot tearing if parameters are suboptimal.

4. Slow Extrusion Speeds: Necessitates reduced ram speeds compared to alloys like 6063 or 6061.

Overcoming the Hurdles: Precision is Paramount
Successfully extruding 7075 hinges on meticulous control:

1. Specialized Die Design: Optimized bearing lengths, angles, and geometries are critical to manage metal flow under high pressure.

2. Expert Process Engineering: Precise temperature gradients, controlled extrusion speed profiles, and optimized quenching are non-negotiable.

3. Premium Tooling: Robust, high-precision dies and tooling capable of withstanding extreme pressures.

4. Rigorous Quality Control: Continuous monitoring ensures consistency and detects potential flaws early.
