This stuff is from my friend, he would like me ask opinions here.
Rotor diameter is 380mm, center disk made by rare-earth alloy, estimate overall weight around 8.7lbs, the price would around 2.65k-2.7k.
It still under endurance test so they do not publish any actual photos yet, only solid drawings.
The friction performance is similar to cast iron rotors and friction resist is better than cast iron or steel, and able to work until 1300F degrees, he said it's a series of all-new alloy.

User will need deep pockets.

I think this rotor is cheaper than CCB, but with very close endurance and more affordable, and less weight.

ls1121

Titanium why not just use iridium if cost is no object.

Boomer111

Must be nice to afford whatever..

Sounds cool for sure.

Let's show something real.
My friend research such elite stuff, initial requirement is from PAGANI.

PAGANI think if it could offer better overall performance, more shape ability, they would take it.
Because my friend carry all related material costs, so they do not limit the applications, but their requirements are really insane and forbid to quote their standards.

Is this for one rotor???

If so, then that's more than $1,000 per rotor more than the ZR1 carbon ceramic rotors!!!

If that's for one rotor, then $10,000 to $11,000 for a set of rotors is not street driving, track day event, or even club racing kind of gear!!

So....I think only pro race teams with super deep pockets would be interested in something like that - and it would have to be WAAAAYYY better than cast iron or even cc rotors.

I don't think there's much of a market for them.

Just MHO.

At that point, why not carbon?

EZZK

This cost was because the manufacture size.
If the build number increased, ideal cost reduce may around 30%, it depend by mho.

Carbon has extremely expensive pads, and they has creep crack issues while watering the rotor at really hot conditions.
And titanium rotors are less weight than CCB but with closed endurance.

Ferocious C6

And titanium won't suffer cracking from rapid heating and cooling or watering?

My fd said the sample material is with special additives and alloys, not usual or registered alloy grade, in heat shock(900C-20C in 3 sec) not shown detectable crack by supersonic check, but it become higher HRC hardness(my fd siad it's quench) and elongation would reduce slightly, when the rotor heat again and cooled naturally, the hardness would reduce but elongation would recover.
Tested after 50 time cycles of 900C heat shock, also no detectable deform(<0.1%) shown.
This alloy has around 72 HRC hardness and 8% elongation in my impression, could adjust hardness and elongation by different heat processes.

And expect overall performance, there is one thing that PAGANI interesting, it's shape ability.
CCB has worst shape ability.

Done been did

And they have a coating on the surface and the majority are sprint cars.

And this article states
http://www.thebrakeman.com/rotortech

"There are rotors made from Titanium, some with various coatings. These rotors are extremely light and are great for certain limited applications, but are extremely expensive and do not perform particularly well dissipating thermal energy."

If you can afford those rotors, you won't be driving a Chevy.....

briancb1

Titanium has horrid wear characteristics. It gets "gummy" with high heat and friction like aluminum. Wtf is this for real?

cclive

This was my first thought also...the wear surfaces would act very much like aluminum, which will not wear well. Also a disadvantage is that the heat conduction properties are not as good as aluminum.

EZZK

My fd said this rotor would finish test around 2 months later, I would post the test result here.

As was stated, corvettes aren't your target group. This car isn't expensive. People whine about the carbon brakes on the zr1.
Look toward Ferrari and Lamborghini forums for more interest.
