On the aluminum brakedisc the reason it shattered is because the friction of the brake pads heated the aluminum disc up mixed with g-foces and uneven casting equaled catastrophic failure. Same thing with the lead disc for the exception of lead is a soft metal so it deformed.

Wish they could have done some measurements like force on the brake pedal, throttle position, rpm chart to give some kind of idea how well each material braked, and it would have been nice if they had been properly machined and balanced too but it was a lot of work to make the demo as it was and quite interesting as it was. Fun to guess at what will happen ahead of time to self test on understanding of material properties. I guessed lead would go slick almost immediately and not be much brake at all and the meltdown was about what I expected. If figured the aluminum would be a bit more braking force and expected it to seize up pretty quickly. Apparently it got hot enough to go pasty. I thought copper would fade out pretty quick too but hang in longer due to high temp strength and heat transfer.

Super interesting idea! I would have expected the aluminum to last the longest, but look what we learned! Love to see more stuff like this!

@@inventor121 Well, Inconel is already used in top-end performance stainless steel rotors, it's stronger than other stainless alloys at high temperatures and has better corrosion resistance, but they tend to be weaker then other stainless alloys when cold so they should be given a warmup lap first on an intense track day. The drawback is that Inconel is very expensive. Roughly $58.95 per pound for Inconel-718 that's been annealed, and can be bought at a minimum size from what I can tell of 1 inch diameter and 12 inches long for 660 bucks. Its not cheap, and it also melts at 1430 degrees Celsius, so good luck melting that down to re-cast it. The better option would be to order a 12x12 plate of 0.375" annealed Inconel-718 for about 1300 bucks and turn it down to a 12 inch rotor. An old 90s Honda Civic has 9 inch rotors, the newer mid-'10s Ford Focus has 13 inch rotors up front, but these rotors are vented and over 10mm thick anyways, and 0.375" is 9.525mm thick so they're a bit skinny for brake rotors anyways. And even then you'd have to make it a 2-piece rotor and bolt it to the bell that holds it to the wheel hub. At least then he'd be free to test the rotor material to the -braking lol- breaking point and put a new rotor on the bell once the old one atomizes itself XD
