7075 Aluminum Sheet

7075 Aluminum Sheet is a cold-processed forged alloy with the characteristics of high performance, high strength, high hardness and good corrosion resistance. Among them, its mechanical properties and anode reaction performance are also very good. It is widely used in aviation, aerospace, military and other fields. It is one of the strongest alloys commercially available.

Common states of 7075 on the market include T6, O, T76, etc. Aluminum alloy materials in different states have their own characteristics and uses, and need to be selected according to specific usage scenarios and design requirements.

What is the difference between the T6, O, and T76 status of 7075?

7075-T6 status: After heat treatment, 7075-T6 aluminum alloy has high strength, good plasticity and corrosion resistance. Aluminum alloy materials in this state are suitable for manufacturing parts that require high strength, good plasticity and corrosion resistance.

7075-O condition: 7075-O aluminum alloy has good plasticity and corrosion resistance. Its strength and hardness are relatively low, but still higher than mild steel, while it has good plasticity and toughness and can be deformed and processed. Specifically, the tensile strength of 7075-O aluminum alloy is 524MPa, the yield strength is 455MPa, the hardness is 150HB, and the elastic modulus is 71GPa.

7075-T76 status: 7075-T76 aluminum alloy has high strength, good corrosion resistance and good toughness. Its strength and hardness are slightly lower than 7075-T6, but still higher than mild steel, while having good corrosion resistance and toughness, and can be deformed and processed. Aluminum alloy materials in this state are suitable for manufacturing parts that require high strength, corrosion resistance and toughness.
