A little info on Ceramic & Metallic friction surface application

Ceramic or bronze friction materials are for higher horsepower applications, quicker shifts wanted in road racing, and a hard-hitting bite for launching for drag racing. The other application for these surfaces is when going to a larger diameter clutch and/or heavier pressure plate is not an option. 

Ceramics and semi-metallics have a higher ‘coefficient of friction than the other materials MDL offers, so it bites harder and holds more power, given the same clamping force.   These surfaces are desired in racing applications for how quickly they engage, as well as for handling extreme heat and abuse.  MDL ceramics have iron pieces in them that create more friction as the material gets hotter.  

For more street-oriented applications, we would use ceramics when we need higher holding power but can’t fit a larger diameter disk (more surface area = more holding power).
If you can’t go to a pressure plate with a higher clamp load, then Ceramic metallic surfaces are a good way to go.  As an example, smaller engines make good power but are limited to sub 10″ disk size.

The 3 attributes that determine the torque rating of a clutch are:

  1. Surface area (disk size)
  2. Coefficient of friction (Kevlar, organic, ceramic)
  3. Clamping force of the pressure plate.  To get higher torque handling ratings, we must increase at least one of those 3.
