Maybe an alloy with some titanium, but it is
considerably heavier than a much larger 
titanium valve for a small block Chevy.

My son gave me an engine valve (not sure if intake
or exhaust, but guessing intake because there is
no evidence of heat/burning on the top surface, just
on the face) from a F2001 formula one car.  Came
with a nice Lucite display base.

The head is quite thin by ordinary passenger car
standards, and flat - without the thickening toward
the stem usually seen.  The stem is absolutely tiny.

The metallurgy involved must be pure rocket science
for this delicate looking piece to not break at
18,000+ rpm.    I am a bit curious, however, why
titanium wasn't used.  Altho the mass is much less
than a normal production car valve, it still has a bit
of heft.  Titanium is used in production car based race
engines, so why not here?

I've usually seen multi-angle valve seats which result
in a thin sealing surface.  The wear pattern on this
valve is quite wide, and surprisingly not symmetrical.
i.e. - the seating area on one side is noticeably
wider than on the other.  I wonder if this is from
uneven wear, or if they were a touch sloppy when
the valve seats were ground.

Too bad I don't know anything of the history of this
particular engine.  But I'm sure it must have been
Schumacher's championship car. <g>.
