A brake rotor for use with a caliper in a brake system is made from a composition having from 20-80 percent by volume of silicon carbide and from 80-20 percent by volume of an iron alloy consisting of: 0.4 to 4.0 percent by weight of total carbon; 1.8 to 18.0 percent by weight of Si; 1.0 to 10.0 percent by weight of X where X is selected from a group consisting of Cr, Mo, Mn, Ni, P and S; and the balance of iron alloy being Fe, the composition having a theoretical thermal conductivity at room temperature of 0.19 to 0.41 cal/cm*sec*deg C.
