Compacted graphite iron brake drum

摘要

A compacted graphite iron brake component for use in a braking system having a final composition of: 3.0 to about 4.0 percent carbon; 2.15 to about 2.60 percent silicon; 0.40 to about 0.90 manganese; and the balance iron. The brake component having a frictionally engageable portion with a microstructure of compacted graphite disposed in a pearlitic matrix.
