Aluminum Sheet 7075

Aluminum Sheet 7075 is a thin, flat shaped sheet 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.

• Exceptional Strength: Among the highest strength aluminum alloys available; comparable to some steels
• Strength-to-Weight Ratio: Ideal for aerospace, military, and high-performance applications
• Excellent Fatigue Resistance: Maintains structural integrity under repeated stress and load cycles
• Moderate Corrosion Resistance: Better than 2024, but often anodized or coated for harsh environments
• Poor Weldability: Prone to cracking when welded; not typically recommended
