Aluminum Extrusion for Energy Storage

The rapid expansion of lithium-ion battery systems for electric vehicles, grid-scale energy storage, and portable power applications is driving significant demand for precision aluminum extrusion profiles in battery module and pack construction. Aluminum's combination of light weight, thermal conductivity, electrical isolation capability (when anodized), and recyclability makes it the material of choice for structural and thermal management components within battery systems.

Our energy storage extrusion solutions are primarily built on 6063 and 6101 alloys. 6063 provides the structural integrity, corrosion resistance, and surface quality required for battery module trays, upper and lower support brackets, and inter-module connection structures. 6101, with its optimized electrical conductivity (approximately 55% IACS), is specified for busbar and flexible connector applications where current-carrying efficiency is a design constraint.

Profile geometries are engineered to integrate thermal management channels directly into the structural section—allowing coolant to circulate through the extrusion itself and eliminating the need for separate heat exchanger components. This approach reduces part count, lowers assembly weight, and improves thermal uniformity across the cell stack. Wall thicknesses and channel dimensions are optimized through thermal simulation to meet module-level temperature management targets.

We work with battery system integrators and EV manufacturers from the concept stage, supporting die design, alloy selection, thermal analysis, and first-article qualification. Dimensional consistency across production batches is maintained to the tolerance requirements of automated module assembly lines.
