I've made brake rotors out of Lead, Aluminium, and Copper.

In this video, I make Brake Rotors from scratch auto of Lead, Aluminium, and Copper alloy. I chose these metals because they are very different one to each other.
It was relatively easy to cast Lead and aluminum. The tricky part was to cast copper because of its height melting point (1084.62 °C, 1984.32 °F).
I didn't know what to expect when I tested the brake disc made of copper alloy. I thought it would melt, but it didn't.
For the Rotor made from aluminum, I melted cans made from aluminum alloy Al 3004 / Al 5182 and some Grounding wire Al5052. I was not surprised that it is brittle and breaks into pieces subjected to massive forces.
Lead is very soft and highly malleable. It made a spectacular show in our video; because of the friction, the Disk started melting, spurting like a stream, and solidified instantly before falling to the ground.
Rotors Weigh:
- Original cast iron 3,9 kg/8.5lb
- Lead 8,2kg/18lb
- Aluminium 1,7kg/3.7lb
- Copper 5,6 kg/12.3lb
The moral of the story: Don't make brake Rotors out of Lead :)
Enjoy!

Great video brings back so many memories of my early engineering years thank you. Just one point if I may the first sand you put into the frame should always be sieved through a fine mesh. This will ensure that the surface is as smooth as it can be. The parting powder the same, I used to keep mine in a hessian sack and pat it over the mould using my hand this gave a finer covering again it helps ensuring the surface stays as smooth as possible reducing machining to a minimum.

These are pretty nice option when you are broken down on the side of the road in need of a new disk, but happen to have have access to the materials, a furnace, the stuff for the mold, and all the tools needed to make it work, possibly a lathe too, then this is absolutely a lifesaver solution so you can limp home and get a new disk.

copper is a really good conductor of heat meaning you oil will carry away less heat but it also means that the copper is more susceptible to deforming under the thermal load. I'd like to see them try this with inconel.

@Avetho Жыл бұрын

@@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

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.

got sick of the video after a few minutes, but you put so much work in I sat here and watched till the end, good job

It would have been good to machine the rotors first to insure there was not runout first and then use new pads with each rotor. If they were machined first and had no runout there would be a lot less variables in the experiment. A lot less vibrations too. Pretty cool test either way.

@@mikeznel6048 The lack of the rotor ventilation isn't really anywhere near as important for this experiment and would be incredibly hard to manufacture and not worth the cost for such an experiment. There are solid rotors out there too so it's not unreasonable to have them be solid for this test since it is not experiencing normal breaking on the road.

@@southernracing2468 I agree. It would have been cool to see breaking distance, and then did high pressure failure test.

Aluminium can successfully be used in rotors, but you need to alloy it heavily using for instance carbide, in order for it to last. The benefits are low weight, high heat transfer, and it pretty much lasts the life of the car. Downsides involve more wear on the brake pads, complicated manufacturing, and higher cost.

GREAT VIDEO... but I'm curious why didn't you balance and turn the rotors??? Turning them may have been difficult with tiny air bubbles in the casting but balancing them seemed important

actually you don't balance a rotor you turn it taking a little to make it true as in able to turn without any wobble

@@jasoncook5307 for one it's called mill balancing and its nothing special and it wouldn't of made a difference here in this video and it would not cause damage to a wheel bearing or vibration . damage will happen if the rotor isn't true that's why they are turned . a rotor is only mill balance at the factory . 8 years making drums and rotors and mechanic for 21 years . if a rotor caused wheel bearings to go bad its just a defected rotor .

@@gamerX-wk7ct Look how off center that hole is! Turn that rotor all you want it is still gonna wobble like mad!! And yes normally you don't need to balance a rotor because the manufacturing process makes them balanced to start... but nothing about this was "normal"
