XM Media is composed of sintered bauxite. Its a granular tumbling nugget that comes in a variety of screen sizes. It is hard, durable and at 140 pounds-per-square-foot, is extremely dense. MFI uses it primarily in burnishing applications, but it also works well for light deburring applications as well as driving other loose abrasives to cut and color parts.

MFI offers a variety of screen sizes the lower numbers being the larger grains and higher numbers having the smaller grains.
