For large lithium-ion battery housing cases

UACJ supplies high-strength aluminum alloys that help to realize thinner lithium-ion battery housing cases. They have been praised for the resulting cost reductions, and have a solid track record in the consumer goods sector. They are also ideal for use with large in-vehicle lithium-ion battery housings.


MG212 is a high-strength material in the 3000 series, which is ideal for use with large, in-vehicle lithium-ion batteries.
