Richwood Industries Tumbling Nuggets
Richwood offers two of the finest random shaped tumbling media available today.
XM is a ‘coloring’ abrasive.
XM is sintered ceramic tumbling nugget with exceptional properties. It is hard, durable and extremely dense. Principally used in mass finishing burnishing applications,
can also be used for light burr removal, radius formation, and is an effective ‘driver’ for loose abrasives in cut and color operations. XM’s hardness, toughness and fine crystalline structure, make it one of the best products available for developing a lustrous, ‘high color’ burnish on all types of ferrous metals, brass and aluminum.

Richwood XM can be used to replace more costly steel media, at lower power and with less machine wear and tear. XM is tougher, more durable and has a higher density than any other ceramic media. It will outlast Competitive ceramic and steel media. Additionally, because XM is harder than the hardest steel, it can be used where steel media is ineffective – e.g. to color hardened steel. At half the weight of steel, cu.ft. – for cu.ft., XM ceramic media is a very economical choice. It is sized closely and uniformly to minimize lodging, will not rust and therefore can be stored wet or dry.

(140-150 lbs./cu.ft.)
XA is the ideal tumbling nugget.

XA is dense, tough, and yet free-cutting, a true microcrystalline fused aluminum oxide abrasive. Its solid structure, super-fine crystal size and carefully controlled chemistry (including titanium dioxide) make it strong and durable. Fast cutting, long wearing and impact resistant over a wide range of demanding applications. With proper compounding, XA is an excellent burnishing media.
