2A11 aluminum sheet plate application

The 2A11 aluminum sheet is a high-strength aluminum-copper alloy known for its excellent machinability and mechanical properties. Its primary applications include the production of medium-strength bolts, rivets, and structural components used in the aerospace and aviation industries. It is also commonly used in transportation vehicles, such as trucks and trains, as well as in construction projects that require durable and reliable structural parts. Due to its good cutting performance, the 2A11 aluminum sheet is ideal for components that need precision machining and assembly. However, because of its high copper content, it may require surface treatments like anodizing or coating to improve corrosion resistance in certain environments.
