Additionally some rotors are constructed from carbon.
Ceramic coated rotors.
There is no easy answer as there are so many different types brands of ceramic and polymer coated rotors out there and they all claim top durability and performance.
They use a mao mico arc oxidation process to bond the ceramic material to the aluminum which they developed to be able to offer these at a reasonable cost.
Your best bet is to be honest about your driving style and environment.
Above is the ceramic coated aluminum disc brake rotor from hsc huang chieh metal which uses a bit of venting on the braking surface and an 8 arm structure to maximize stiffness.
Tested to withstand 400 hours of salt spray equivalent to 18 southern michigan winter months coated brake rotors edges and vanes stay cleaner longer optimizing air flow and performance.
If most of your driving is just commuting to and from work cast iron brake rotors are probably exactly what you need.
On most modern cars brake rotors are made from either cast iron or carbon ceramic materials.
Ceramic is the highest performance brake rotor available today.
These pads use ceramic compounds and copper fibers in place of the semi metallic pad s steel fibers.
This allows the ceramic pads to handle high brake temperatures with less heat fade provide faster recovery after the stop and generate less dust and wear on both the pads and rotors.
Featuring an e shield protective coating to reduce corrosion and oe specific vane design for effective braking power wagner e shield rotors are packaged in a vapor corrosion inhibitor vci bag eliminating the need for an oil coating which reduces prep time.
Special polymer coating also keeps rust from forming along the outer edges of the pad swept area to prevent edge lift.
Premium wagner e shield rotors wagner e shield rotors are engineered for maximum performance.
But porsche has recently implemented another type of brake rotor that s set to revolutionize the.
It is important to note that the coating itself is designed to be worn away in certain areas.
