Aluminum Round Bar 7075

Aluminum Round Bar 7075 is a round shaped bar of 7075 aluminum alloy. This is one of the highest strength aluminum alloys available. Its strength-to-weight ratio is excellent. It is ideally suited for highly stressed aircraft parts.

• Ultra-High Strength: One of the strongest aluminum alloys available, comparable to many steels
• Excellent Strength-to-Weight Ratio: Ideal for weight-sensitive, high-load applications
• Superior Fatigue Resistance: Performs exceptionally under repeated stress cycles
• Fair Machinability: Machines well, though tools may wear faster than with softer alloys
• Poor Weldability: Not recommended for welding due to high cracking risk
• Moderate Corrosion Resistance: Better than 2024
