DU incased in the titanium skid plate.

How would that affect an F1 car ?
Is it illegal to used it in F1 ?

Tungsten and tungsten based alloys are the prefered choice of material for ballast, usually in the form of an alloy with nickel-iron or nickel-copper since that makes it easy to machine. Tungsten can offer the same density as depleted uranium, or greater but without the handling problems or uranium. Depleted uranium is cheaper since it's a byproduct of uranium enrichment, tungsten is more expensive but has none of the restrictions that applies to uranium (which will add to the cost even if you get the material cheap).

To use depleted uranium you must hold a license for it, and you are'nt allowed to throw it away.

That the case in eg the USA which is relatively lenient in the possession and use of hazardous materials compared to countries like for instance Korea.

I'm not sure about the export status of F1, but since it travels around the world I can imagine that it must comply with the local regulations of the countries visited.

In that case the use of DU would certainly not be worth the bother, especially since there are good alternatives available as you say.

but how about using ballast in the skid plate? that is illegal , but how would the FIA find out?

how is the scrutineering conducted?

Why DU? Just go crazy and use osmium.

This. Osmium is denser.
