Why F1 is so expensive

[HereWeGoAgain]

No one uses Titanium or Carbon fiber for e.g. high pressure valves or camshaft parts - they are all eloxed aluminum via direct CNC operations and Titanium aluminide inter-metallic compounds with a stiffness close to 40 GPa/g·cm3parts, for cold press-sinter parts - which then are partly deburred with a deburring maschine (ADV) and not via a CNC center.
You have never produced any F1 or Motorsport regulated engine parts - so you simply don't know about material specifications and the entire handling process.

Your NASA comparison (who knows what part you actually produced) simply doesn't hold.

Yep..
Which is why I said titanium is a poor choice for parts that get repeatedly hit over and over again,it's to brittle.
It works just fine for consistent pressure.

The procedure to make a single bolt.

That is custom made, probably to a Class 3 fit in what is called Six Sigma quality.

In 1978, I saw bolts like that go for about $170 a piece.

 

[toobfreak]

it's the multiple inspections, and testing of the finished product that incurs the expense.

Much the same can be said for the space program.

Nothing much to do with Titanium supposedly being brittle as such - Titanium is very ductile and will stretch almost half its length before breaking.
Therefore Titanium is used in all kinds of F1 or Aerospace parts. E.g. Turbine blades, frames, wings and e.g. F1 wheel carriage parts (high stress and vibration loads)

The issue is, pressure in combination with heat, reacting onto the oxygen beheld within Titanium - e.g. engine valve parts, would crack - If one could process titanium with optimal properties (low oxygen content) at a cost comparable to aluminum, you would find multiple extra uses in cars, trucks, aircraft and ships.

Uh no.
Titanium will break before it'll stretch.

Uh no.

Nope. Titanium is only brittle at room temperature. Heat it up and it changes to ductile, and quite malleable.

So you're saying it loses its strength when hot.
So tell me what good is titanium if it fails when it gets hot?
I mean the whole purpose of titanium is it's strength and weight.

Titanium has a high melting point - and remains rather stable at temperatures up to 580F, but it doesn't easily dissipate heat, due to it's low thermal and electrical conductivity, which can cause heat build-up in the metal - and eventually catch fire. Therefore you won't find Titanium parts in car engines - connected or exposed to the combustion process, jet or rocket motors.
