brake rotor material
(OP)
I am looking for advice on material selection for machining brake rotors. For a small buget, i am looking into grey cast iron, or some steels. I've considered 1018 colded drawn, or 1080 steel (i believe its the same as on most motorcyles), I haven even a slight interest in 4130 as a past friend has succesfully used this. As far as the grey cast iron goes, i'm finding it hard to find a specific type to look at.
Any tips or suggestions would be appreciated, I am working on a limited buget and do not wish to consider Al-MMC or any ceramics because of cost. But overall some direction would be appreciated. Thank you.

I am now actually consider machining cast iron plates for rotors. After reading the sae.pdf and some other resources I think I'd like to use the gray cast iron (seems like most grades will work with little differences between them).
I will be modeling the rotors to work with a single piston (dual action) caliper, like on most motorcycles, so i wont need the rotors to float or anything. I do not have the space for vented disks and the are pricey to manufacture anyway. Does anyone know of any references on cooling theories for rotors?
Lastly, i am aware that i will need to find pads with a specific friction coeficient depending on the rotor material used. Again, does anyone know of any sites or references?.. I will continue searching.
Thank you in advance

Here's a decent brake book. Used to be a bargain but its out of print with craxzy prices on Amazon

Our lathes don't have brakes, but the technician said he could do better than 1mil for the parallel surfaces and same for the 5mil roundout. I looked into motorcycle rotors already but found the bolt pattern and geometry to only complex the current situation. I think I am now interested in either mimicking a motorcycle rotor, but with my own geometry, or again, trying to find some gray cast iron with the correct graphite composition.
What grade of stainless are bike rotors made of... I cannot find this anywhere. Any chance they are 304 or 316, i can get that real cheap. Thanks again everyone, i really appreciate it.

Browse the first source and you will see how cheap they can be. I am buying mine from the first source (being in Australia) and he will make any design as they are individually laser cut anyway.
The 2nd source is Italian and the 3rd is in USA.

A brake lathe is made to refinish brake rotors. They cut both sides at once to help ensure good parallelism, which can be VERY challinging doing one at a time.
