Product Introduction

7075 Alloy Aluminum Sheet

What Is 7075 Aluminum Sheet?

7075 alloy aluminum sheet plate belongs to Al-Zn-Mg-Cu super duralumin 7000 series aluminum alloy, which is a cold-treated forging alloy with high strength and hardness, far better than soft steel.

Due to the fine grain structure inside 7075 aluminum alloy, it has excellent deep drilling performance, enhanced wear resistance of tools, good mechanical properties and anode reaction.

Features Of 7075 Aluminum Sheet

Alloy 7075 aluminum sheets have been and remain the baseline standard with a good balance of properties required for aerospace applications.

7075 aluminum sheet is among the highest strength alloys available and is used in highly stressed parts.

Corrosion resistance and machinability are rated as fair, though the addition of chromium provides good stress-corrosion cracking resistance in 7075 aluminum sheet products.

As with alloy 2024, alloy 7075 is available in the bare form or in the cladding ("Alclad") to offer even further protection from corrosion.
