Thermal properties of the materials are another important fac
tor. Due to the temperature dependent permeability values of the
ferromagnetic materials and the MR fluid viscosity, heat generated
in the brake should be removed as quickly as possible. In terms of
material properties, in order to increase the heat flow from the
brake, a material with high conductivity and high convection coef
ficient has to be selected as materials for the non-magnetic brake
components. Aluminum is a good candidate material for the ther
mal considerations.
