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!

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.

@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

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.

@@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"

I see so many people worried sanding lead paint on KZfaq, and then you guys are over here throwing lead confetti all over the shop! Fascinating video 😂

I was surprised at how well the copper rotor held up.

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

Lead is what got me really interested. I hope you were really careful with the clean up on that. Handling lead in general, especially in the sense of it becoming particles in the air needs the utmost to care and bring safe.

Remember that the Lord Jesus Christ died on a cross for you because He loves you so much. He then rose up from the dead three days later. The Ten Commandments are called the moral law, (most of us are lying thieving blasphemous adulterer at heart and deserve hell) you and I broke the law, Jesus paid the fine. That’s what happened on that cross. By believing that Jesus died on the cross and rose up from the dead 3 days later and not just confessing your sin, but also repenting of all sin you have done and putting all your trust in Him in prayer, He will grant you everlasting life as a free Gift
