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.

The failure on the lead rotor was amazing! The copper actually looked like it could be a viable option. I would be quite interested to see a video where you cast a full set of copper rotors (with some machining to insure they're properly sized and balanced) and test them for performance, reliability, and longevity against standard rotors.

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. Especially how sticky the aluminium becomes when heated up, you wont even need to press the pedal after a few miles😂

Wow, there's going to be a ton of dust, my lungs hurt just watching😱 I never thought they'd go to the extent of sand casting copper, aluminum and lead to replicate brake rotors. These are things that an average hobbyist would never try, as they would take too much time and effort. But they actually did it. Nicely done! "Achieving these things silently" - it's been a while since I've seen the true essence of a KZbinr.😂

copper would do well in a test like this with its high thermal conductivity the longevity would be questonable though and the cost is the final nail in the coffin

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
@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

Normal brake discs are not steel, they are cast iron. Also, not only would you end up with a disc that would wear a lot faster, you'd end up with a heavier disc. Why would you want that? Plenty of pads out there that can deal with the heat.
