For frames and structural materials

UACJ supplies a variety of high-strength aluminum alloy sheets for the mobility sector, where there is a growing demand for lightweight products. They have superior strength and weldability, and as well as application in automobiles, they are ideal for use as frames and structural materials, including in railway rolling stock.

Features

  • Comprehensive type
    Starting with the 75S high-strength aluminum alloy sheet, materials can be selected according to the specific application.
  • Promoting lighter weight
    As the sheets are strong enough to be used in frames and structural materials, they help reduce the weight of the components.
