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!

Make another lead brake disc push it hard then go to a mechanic and tell him your brake is kinda strange
I respect this.
Now do you goto a doctor for lead poisoning? Or a mechanic for brake rotor poisoning? Hahahahahahaha
VERY CLEAR !!! MANY THANKS FOR YOUR KIND SHARING. Ciao Nik from IT
Hey man you sleep good last night? Naw. Why? I was up late watching stuff. Whatching what ? I don't wanna say.
Amazing, science and cars coming together in one vid it’s a dream come true
Good to know! Someone needs a person like you some where👍👍👍

そう言えば、ロータスエリーゼの初期モデルはブレーキディスクがアルミ製だったんだよな。
nice
1:45 a pinch of salt. 😂
This is cool
Instead of sending that gearbox to skip it should be stripped and melted for future projects. As for me, it would be interesting to see next melting project including gearbox disassembly.
Cooper is actually a decent material for a brake disk or brake pads… Unlike aluminum which is brittle and lead which is soft…..
To be fair i was impressed by the aluminum surviving so long.
Bro is funny
soldering wire?
素材による違いの観察も興味深いけど、バランスを取ってないブレーキローターの動きも興味深い
おいしそう
Realmente son pruebas extremas ya que los discos está sin maquinar sin planitud y excéntrico,sin ventilación.
No me parecen pruebas coherentes.sino destructivas
If you were really as bored as you appear to have been, why didn't you just make a rotor out of cheddar cheese? Or clay? Or epoxy resin?
a titanium one too ?
Try different materials for brake pads too
Put the spin on it
ただの鋳造だと成分にムラが出来て真円が…出来るか？が疑問
各金属の放熱比較で言えば…
銅は熱の伝導がアルミや鉄よりも良いから動画の発想は、面白いですね。
From what I know about brake rotors, I'd imagine none of these are very good lol, interesting enough for me to click tho
You should first put these rotors thru lathe. Do make the surface better
Maybe next time, you can make some out of bronze or Nordic gold.
Gotta appreciate how your team was willing to expose themselves to a bangload of lead dust for that last experiment with the lead rotor! 🤗
Absolute useless exercise
You know that you can use an Aluminum Matrix material for brake rotors and they work extremely well. The material was an aluminum powder integrated with carbide in a ball mill for a month or so. Then melted and cast into vented rotors. It required diamond tooling to barely machine and required a new tap that was tini coated to thread form not cut each thread. They were extremely hard wearing and required a specialist pad material . However they were able to dissipate far more heat and when tested in a race car that would usually require new rotors and pads (cast iron rotors) after each race they only needed pads and the rotors lasted a season of 15 races. I saw them when they came back and they still looked good enough to use for another 15. However they didn't like severe thermal shock and would buckle and extrude if under pressure when that occurred. Thermal shock being water flooding when at max operating temp. Also sitting stationary when at operating temp with the pads applied under pressure, they would chill in that spot and then vibrate the pedal. On the race car they made a huge difference braking wise compared to an equal weight ferrous setup. Copper has also been used historically for brake pads as well as clutch facings. in the 60's racing minis would use copper pads on iron rotors as the material back then didn't like the high heat and would produce a gas barrier reducing effectiveness, unlike copper that would just make the iron glow red.

I love how he has a check engine light and just doesn't care…
I can smell the fumes produced..
Диски надо проточить на токарном станке, отбалансировать, и потом проводить эксперименты. А так это хуйня

You don't skim the drauss from top?
Lead is obviously superior
даунито
Should of taken it to repair shop with the broken lead BRAKE DISK
Which sand did you use for the modeling?
This is pure ASRM for car lovers and mechanics.
How about lead – poisoning? Its dangerous to even melt it, machining is dangerous, and lead brake rotor? Crazy.
Oh, transmission blow? No problem. We’ll just make another one out of aluminum.
I am weirdly surprised that the copper one held up better than the other two
早送りのところでちょっとソルトバイしたやろ！
