Specific Prohibitions and Restrictions

In Simple Terms

F1 teams cannot use shape memory materials or 3D-printed parts containing beryllium in their cars, as these materials are too advanced or potentially harmful. There are also restrictions on using expensive precious metals and certain specialized metal alloys unless they're specifically approved.

• Shape memory materials are banned (except for piezoelectric sensors which are allowed)
• 3D-printed (additive manufactured) parts containing beryllium are prohibited
• Precious metal alloys with more than 5% combined platinum, ruthenium, iridium, rhenium, or gold are restricted unless specifically listed as permitted
• Foil metallurgy and intermetallic alloys are restricted unless approved in article C15.4
