What is Aerospace Grade Aluminum?
Aerospace aluminum plate and sheet are specialized types of aluminum alloys that are used in the aerospace industry due to their high strength-to-weight ratio, corrosion resistance, and other desirable properties. These are typically made from high strength aluminum alloys such as 2024-T3, 7075-T6 and 6061-T6.
The aerospace industry uses aluminum sheet and sheet in a variety of applications, including aircraft fuselage and wing skins, structural components, and engine components. These materials are often subjected to extremes of temperature, pressure and other environmental factors, so they must be able to withstand harsh conditions while remaining lightweight and durable.
