What materials are used in the Tesla Cybertruck's exoskeleton?

What is Ultra-Hard Stainless Steel

Ultra-hard stainless steel is a premium grade of steel alloy that combines strength with corrosion resistance. Tesla uses a specific type called 17-4 PH stainless steel, which is much harder than ordinary steel. This material can withstand significant impact and pressure without denting or deforming, making it ideal for a vehicle's outer shell.

Why Tesla Chose This Material

Tesla selected ultra-hard stainless steel for the Cybertruck to create a nearly indestructible exoskeleton. The material's extreme hardness allows the vehicle to have a flat, angular design with minimal curves, which reduces manufacturing complexity. The steel is also resistant to rust and corrosion, providing long-term durability without frequent maintenance.

How Thick is the Material

The stainless steel exoskeleton is approximately 3mm thick, which is thinner than traditional vehicle steel but much stronger due to its ultra-hard composition. This thickness allows Tesla to maintain the vehicle's weight efficiency while providing maximum protection and durability.

Durability and Protection

The ultra-hard stainless steel exterior is designed to resist dents, scratches, and impacts that would damage conventional vehicle materials. The exoskeleton also provides structural support for the vehicle, working as both the outer body and a load-bearing frame component.
