Abstract
A brake drum has its strength elevated in its disk portion. The brake drum is formed from a composition having ceramics dispersed in a matrix. The disk portion has a high ceramic content and thereby a high strength. The brake drum has a disk portion and a cylindrical portion. The disk portion has a first ceramic content by volume and the cylindrical portion has a second ceramic content by volume that is less than the first ceramic content by volume as a result of the application of a higher compression ratio to the disk portion.
