7075 aluminum plate is used to manufacture aircraft structures and other high-stress structural parts that require high strength and strong corrosion resistance, such as upper and lower wing panels, girders, bulkheads, etc. After solution treatment, it has good plasticity and is particularly effective in heat treatment. It has high strength below 150°C and has particularly good low-temperature strength. It has poor welding performance and a tendency to stress corrosion cracking. Double-stage aging can improve SCC resistance.
Typical Applications
What is 7075 aluminum used for?
7075 aluminum is used for aerospace applications, high-stress structural components, and military-grade equipment due to its high strength and excellent fatigue resistance.
What is the strongest aluminum plate?
The strongest aluminum plate is typically made from 7075 aluminum alloy, which is known for its exceptional strength and toughness.
Is 7075 aluminum better than 6061?
7075 aluminum is stronger and more fatigue-resistant than 6061 aluminum, but 6061 is more corrosion-resistant and easier to weld.
Is 7075 stronger than steel?
7075 aluminum is strong but not stronger than most grades of steel, although it offers a superior strength-to-weight ratio.
