By all means link me to something that suggests this because this site says steel is the best material to use for low frequency EMI shielding. Also if memory serves, Tesla already uses some titanium in its vehilces and its not sufficient. Part of the problem with titanium is while paramagnetic, it can align with the surrounding magnetic field and thus become magnetic. I think this is part of the problem with it as a metal implant. Better material for insulating is a ceramic like Si3N4.

Using thick conductive metal material such as steel, which often works well, but the drawback is the weight. Aluminium or magnesium are much lighter than steel, but they have insufficient low-frequency shielding properties and, therefore, cannot be used in this application

What's particularly good about Cybertrucks exoskeleton is the fact its magnetic so that the external magnetic fields will interact with the steel and then run along the exoskeleton thus shileding the inside from those external fields until it reaches saturation point. Id think an insulator is needed on the interior of it however.

Thus, a shell of high permeability material built around an area will effectively keep most of the magnetic field lines in the actual shell itself and out of the area inside the shell.

What might that look like?
