Helping to Make Vehicles More Lightweight

We offer a variety of aluminum alloy sheets that have the strength, formability, corrosion resistance, surface quality and other characteristics needed for automotive body panels. These are used as exterior panels—for engine hoods, trunk lids and doors—as well as for interior panels.

Features

  • The TM Series (type 6000 alloy) is bake hardened, making its lightweight and strong.
  • The TG Series (type 5000 alloy) is highly ductile, lightweight and with high formability.
  • We offer a variety of products with different surface finishes, surface treatments, lubricants and sizes.
Specification Description
Material Type 5000 or 6000 rolled sheet alloy
Surface finishes Dull or milled finished
Surface treatments Acid washing possible
Lubricants Can be coated with various types of lubricant
Shapes Coils and sheets (longitudinal circular sheets also possible)

Applications

Automotive panel materials (engine hoods, trunk lids, doors, etc.)

  • *1 Baking conditions: After applying 2% pre-distortion, test value after 20 min at 170°C
  • *2 The “stretcher-strain mark” (SS mark) is a distortion pattern that appears during forming.
  • *3 The BH (bake-hard effect) is the property of strength increased by applying the bake coating.
