The Critical Role of Aluminum Extrusions in Modern Electric Vehicle (EV) Design

The transition to electric mobility is transforming automotive engineering at a pace the industry rarely has experienced. As manufacturers quicken the pace toward battery-electric platforms, one engineering priority consistently rises to the surface: reducing weight while enhancing structural performance and safety.

Aluminum extrusions now stand out as integral to the realization of those objectives. From battery enclosures and space frames to crash management systems and thermal components, the modern architecture of electric vehicles is underpinned by extruded aluminum profiles.

As one of North America’s leading producers of both custom and standard aluminum extrusions, Can Art Aluminum Extrusion Canada Inc., works directly with automotive OEMs and Tier 1 suppliers to deliver precision-engineered components that meet the demands of a rapidly evolving industry.

This article explores why extruded aluminum has become indispensable to EV design, and how Can Art Aluminum Extrusion Canada Inc., supports this high-growth market.

Why Aluminum Has Become Central to Electric Vehicle Engineering

EV platforms put new stressors on vehicle structure: heavy battery packs, more severe safety demands, higher thermal loads, and the drive to maximize driving range. The inherent material advantages of aluminum make it uniquely suited to this environment.

Lightweighting Improves EV Range and Efficiency

As one of the lightest metals, aluminum is roughly one-third the density of steel, which makes it one of the most effective weight-saving materials. Reduction of mass directly improves the range by lowering the energy required for acceleration and maintaining speed.

Lightweighting also reduces structural loads, thus allowing smaller motors, brakes, and suspension components, further compounding efficiency improvements.

High Strength-to-Weight Ratio for Structural Components

Modern 6000-series automotive alloys, such as 6061, 6063, and 6082, exhibit excellent combinations of tensile strength, corrosion resistance, and extrudability. These combinations support a wide range of structural applications, including underbody reinforcements, cross-members, and body-in-white elements.

Superior Energy Absorption and Crashworthiness

According to the Aluminum Association, aluminum structures can absorb more crash energy per unit mass when compared to steel, making them ideal for impact management components in EVs. Controlled deformation characteristics improve occupant protection and safeguard high-voltage battery systems.

Thermal Management and Heat Dissipation

Battery modules, while charging and operating, generate heat. Thermal conductivity of the alloy is appropriate for structural parts such as battery trays, heat sinks, cooling plates, and thermal shielding.

Where Aluminum Extrusions Appear in Modern EVs

Extruded profiles offer some unique advantages over stamped or cast components, including continuous grain structure, hollow multi-chamber options, and tight dimensional accuracy.

The most important EV components using the technology of aluminum extrusion are listed below.

  1. EV Battery Enclosures and Trays

Among other structural parts, the battery enclosure is one of the most structurally demanding components in any EV. It has to be rigid, thermally stable, crash-resistant, and sealed against environmental exposure.

Extruded aluminum finds extensive applications in:

  • Side rails and longitudinal beams
  • Cross-members and stiffeners
  • Battery tray perimeter frames
  • Integrated cooling channels and heat sinks

Aluminum represents a balance of strength, rigidity, corrosion resistance, and thermal conductivity that few other materials can match. In fact, several EV platforms around the world, including those by Ford, Tesla, and General Motors, utilize aluminum-intensive battery housings.

  1. Aluminum Space Frames and Body-in-White Structures

Extruded aluminum allows for the manufacture of multi-hollow profiles, load-carrying beams, and structural reinforcements that act as a backbone to body-in-white systems. These include:

  • Rocker panels
  • Roof rails
  • A- and B-pillar reinforcement sections
  • Front and rear subframe elements

The space frame design in aluminum provides an optimum blend of stiffness with minimum mass to support both crashworthiness and ride dynamics.

  1. Crash Management Systems

Crash management in EVs is becoming more challenging as it must consider occupant protection along with the protection of high-voltage systems.

Extruded aluminum is widely used in:

  • Crush cans
  • Front and rear bumper beams
  • Side-impact energy absorption structures

Extrusions can be engineered to deform in predictable ways, thus providing reliable and consistent crash response.

  1. Thermal Management Components

EV battery performance depends heavily on temperature control. High conductivity of aluminum supports efficient heat dissipation in:

  • Cooling plates
  • Heat sinks
  • Battery module heat spreaders
  • Power electronic housings

Extrusions can be produced with integrated channels or fins to optimize cooling performance without adding unnecessary mass.

Why Extruded Aluminum Is Ideal for EV Applications

Design Flexibility

Extrusions enable complex, multi-functional shapes, directly integrating mounting points, channels, and internal webs into a single profile, that reduce assembly steps and machining requirements.

Repeatable Precision

Extruded components have tight dimensional control that allows for automated assembly and vehicle integration.

Corrosion Resistance

Natural oxide layers and optional anodizing provide long-term protection in demanding environments.

Compatibility with IATF 16949 Automotive Quality Requirements

The Windsor plant of Art maintains the IATF 16949:2016 certification to ensure quality management systems compliant with automotive standards.
