Beryllium in engines drama

[ACRO]

Here is a picture why ferrari urgently motivated FIA to ban any +40gpa alloy for "health reasons" ...

The BMEP of the 2000 tipo 049 was average at best with a flat spot around 14500. The top end was respectable but we see that above 17500 , latest above 17800 , the output dropped again rapidly , the flame front propagation was simply at its very edge with the 96mm bore and this revs .

The engine reved to this limit without the need of al/be pistons since the stroke was very short - and berrylium would not help anything here.

Ilmor with its longer stroke had a better midrange but would blow up reving to +17500 to reach a similar topend without al/be .

Ferrari in 2000 was 96x41.4 and ilmor was 93.5x43.67 .

More than 2mm difference in stroke , that was much at 17500 rpm .

nonsense !
there is no metal in F1 cars or elsewhere in engineering that has an elastic modulus below 40 GPa

Here is the rule change from the FIA Technical Regulations 2001
15.1.2) No parts of the car may be made from metallic materials which have a specific modulus of elasticity greater than 40 GPa / (g/cm3).

So what I said was completely correct.
And maybe next time you should do your research first.

what you said was far from correct

the elastic modulus E is the actual value (GPa) for each metal ie c.70 for aluminium c.210 for steel
the FIA's modulus is a fictitious value ie the actual value normalised for density
this for beryllium is uniquely high but unimportant in F1

except as a way to reduce the Be content of pistons etc
it looks as if this was effectively a ban on eg 62% beryllium but maybe not on (say) 10% beryllium
to satisfy both parties

And I never talked about anything other than the FIA value....

Was beryllium even worth it when BMW was making the most powerful engines from 2000 to 2008? Were they using beryllium?

Also, has aluminum 6061 or 7075 been allowed in F1? It has a tensile strength of 60,000 to 70,000 psi. It is used in NHRA engine blocks for Top Fuel/Funny Car racing (11,000 HP, 334mph). Has anyone made pistons, valves, camshafts, crankshafts and bearings out of it?

imo BMW had enough problems without involving beryllium

6061 is a rather general purpose material
7075 is stronger
presumably the intent here is for machining from solid ie 'billet'
7075 probably wasn't publicly available when F1 was first written
aluminium alloys have eg poor fatigue properties at elevated temperatures
so they are self-banning

Yes, I was referring to solid billet aluminum. Could it have a useful purpose in F1?

Maybe, make parts of the engine out of solid billet aluminum so they can last the entire season to cut down costs and increase durability, a higher upfront initial cost of the product but in the end it saves money with fewer parts replaced through out a season?

Teams can use the same engine block for the entire season or even more. In Nascar, they use engine blocks made out of CGI and they last the entire season.

Alan Johnson (AJPE) makes the solid billet aluminum blocks for many NHRA Top Fuel/Funny Cars...
