At HDM, we have developed aluminum alloy sheets that are perfect for cylindrical, prismatic, and pouch-shaped lithium-ion battery cases based on the current application of lithium-ion batteries in various fields. Our aluminum alloy materials are user-friendly, compatible with various deep-drawing processes. HDM’s aluminum alloys offer high strength and excellent laser weldability, allowing for ultimate thinning of your casing material with ease.
The battery is a critical part of new energy electric vehicles, and the quality of the housing material affects the safety and lifespan of the vehicle. The aluminum housing material supplied by HDM is easy to shape, resistant to high-temperature corrosion, has good heat transfer and electrical conductivity, and is perfectly suited for the laser sealing process used for square battery cases.
