Aluminum plate 2A11 2A12 2A14 2024 2017 LY12

These aluminum plates belong to high-strength aluminum-copper alloy plates, with copper as the main alloying element. They offer excellent strength, fatigue resistance, and good machinability, though corrosion resistance is relatively lower. They are commonly used in aerospace, transportation, and high-strength industrial structural components.
These aluminum plates can be anodized, coated, or mechanically processed, making them suitable for aircraft structural parts, automotive chassis, industrial equipment, and high-strength structural components.

Application

Molds, precision parts, large frames, bridges, large shells, truck components, etc

It is used for alloy casting of structural parts such as aircraft wall panel, front beam girder, joint, strut and landing gear, beauty instrument, notebook shell, etc.
