Materials allowed to be used are quite well defined. This is just a short outtake. For full reg, concerning materials go to http://www.fia.com/sites/default/files/ ... -12-09.pdf

Materials and construction
5.16.1Unless explicitly permitted for a specific application, the following materials may not be used anywhere on the power unit :
a) Magnesium based alloys.
b) Metal Matrix Composites (MMC’s).
c) Intermetallic materials.
d) Alloys containing more than 5% by weight of Iridium or Rhenium.
e) Copper based alloys containing more than 2.75% Beryllium.
f) Any other alloy class containing more than 0.25% Beryllium.
g) Tungsten base alloys.
h) Ceramics and ceramic matrix composites.
The restrictions in Article 5.16.1 do not apply to coatings provided the total coating thickness does not exceed 25% of the section thickness of the underlying base material in all axes. In all cases, other than under Article 5.16.3(b), the relevant coating must not exceed 0.8mm.
The restrictions in Article 5.16.1(h) do not apply to the following applications :
a) Any component whose primary purpose is for electrical or thermal insulation.
b) Any coating whose primary purpose is for thermal insulation of the outside of the exhaust system.
Magnesium based alloys, where permitted, must be available on a non-exclusive basis and under normal commercial terms to all competitors. Only those alloys covered by ISO16220 and approved by the FIA may be used.
