Abstract In order to study the brake drum material of compacted graphite cast iron with superior performance and controllable cost, dry sliding friction and wear tests of compacted graphite cast iron and gray cast iron with different vermicular rate were carried out by MG-2000 friction and wear tester. The results show that the wear resistance of compacted graphite cast iron is 1.4—4.5 times higher than that of HT250 under the same conditions, and the superiority is more obvious with the increase of load and wear speed. The wear resistance of compacted graphite cast iron decreases with the increase of vermicularity, and the wear resistance of Ru60 is 69%—76% higher than that of Ru90.
