When electric car pioneer Tesla CEO Mr Elon Musk had introduced the Cybertruck in 2019, he had said that the electric truck's exoskeleton would be made out of a special cold rolled stainless steel alloy that would make it bulletproof. It would also be corrosion-resistant, so it would not need painting. The patent application for “Ultra-Hard Cold-Worked Steel Alloy” was filed in August 2022 and was published last week. The patent says that the special alloy will be used for at least one exterior panel and the vehicle's body. It also says that the vehicle architecture is designed in such a way that the vehicle's outer panels also contribute to the structural performance. Based on the patent filing, the truck's body will feature a corrosion-resistant monolithic metal sheet, which makes applying anticorrosion coating unnecessary. The steel alloy can also be used without a paint coating, which is unusual in the automotive industry. The patent goes into deeper detail about the metal's hardness at 400-500 HV and strength of minimum 1,100 MPa. The Cybertruck is due to come to market later this year, with large-scale production coming in 2024. However, there hasn't been any official information about the company or companies that will manufacture the new metal for Tesla. That said, there's been some talk on social media about a company called Steel Dynamics. Steel Dynamics has a huge factory in Texas that's not too far from Tesla's Gigafactory. Cybertruck is designed to have the utility of a truck with sports car performance. Built to be durable, versatile, capable and high-performance both on-road, Cybertruck is built with an exterior shell made for ultimate durability and passenger protection. Starting with a nearly impenetrable exoskeleton, every component is designed for superior strength and endurance, from Ultra-Hard 30 X Cold-Rolled stainless-steel structural skins to Tesla armor glass. With up to 3,500 pounds of payload capacity and adjustable air suspension, Cybertruck is engineered with 100 cubic feet of exterior, lockable storage, including a magic tonneau cover that is strong enough to stand on. With the ability to pull near infinite mass and a towing capability of over 14,000 pounds, Cybertruck can perform in almost any extreme situation with ease. It seats six comfortably with additional storage under the second-row seats. Complete with an advanced 17 inch touchscreen with an all-new customized user interface.
