7075 aluminum sheet is a high-strength aerospace-grade aluminum alloy sheet that is used in a variety of applications where strength and durability are critical. It is composed primarily of aluminum, zinc, and copper, with small amounts of magnesium and chromium added to enhance its strength and corrosion resistance.
Features of 7075 aluminum sheet plate
One of the key features of 7075 aluminum sheet is its excellent strength-to-weight ratio. This alloy has a tensile strength of over 83,000 psi and a yield strength of over 73,000 psi, which makes it one of the strongest aluminum alloys available. Additionally, it has a high resistance to fatigue, which makes it an ideal choice for applications that require repeated or cyclic loading.
Another important feature of 7075 aluminum sheet is its high corrosion resistance. This alloy has good resistance to both atmospheric and seawater corrosion, which makes it an ideal choice for marine and aerospace applications. It is also resistant to stress corrosion cracking and exfoliation corrosion, which are common forms of corrosion that can occur in aluminum alloys.
In addition to its strength and corrosion resistance, 7075 aluminum sheet also offers excellent machinability and formability. It can be easily machined using standard machining techniques, such as cutting, drilling, and milling, and it can be formed using standard forming techniques, such as bending and stamping.
7075 T6 aluminum sheet plate
7075-T6 is a specific type of 7075 aluminum alloy that has been heat treated to achieve a specific combination of mechanical properties. The “T6” designation refers to the heat treatment process used to create this material, which involves heating the aluminum to a specific temperature and then rapidly cooling it to create a high-strength, high-durability alloy.
The T6 heat treatment process for 7075 aluminum sheet typically involves heating the material to a temperature of around 990°F (532°C) for a period of several hours, followed by rapid cooling in a quenching solution, such as water. This process creates a microstructure within the material that consists of small, uniform grains, which contribute to the material’s high strength and toughness.
7075 T651 aluminum sheet plate
7075-T651 is a specific type of 7075 aluminum alloy that has been heat treated to achieve a specific combination of mechanical properties. The “T651” designation refers to the heat treatment process used to create this material, which involves heating the aluminum to a specific temperature and then cooling it slowly to create a high-strength, high-durability alloy.
The T651 heat treatment process for 7075 aluminum sheet typically involves heating the material to a temperature of around 350°F (177°C) for several hours, followed by air cooling. This process creates a microstructure within the material that consists of small, uniform grains, which contribute to the material’s high strength and toughness.
