Creating a long-lasting rotor starts with a precision blend of metallurgy. FleetX metallurgical engineers consult with OE teams to determine the best grade of iron alloys for rugged air disc braking applications.
High torque and high-heat applications like those in the air disc environment will create more than 15,000 foot pounds of torque and temperatures that exceed 1,500 degrees F.
Some manufacturers focus on creating high tensile strength rotors that do not wick heat away from the pads. This results in noisy rotors that can trap heat against the pads and shorten pad life.
Others focus on adding Carbon to the rotor to wick heat away. This eliminates noise by softening the rotor, but results in increased rotor wear.
