SS Metal Media is made of small, cylindrical, or spherical-shaped pellets that are made from stainless steel, which is a high-strength and durable material that resists corrosion and wear. When used in a vibratory or rotary tumbling machine, this works to remove burrs, sharp edges, and other imperfections from the surfaces of the parts, while also smoothing and polishing the surfaces to a desired finish. SS Metal Media is a more environmentally friendly alternative to traditional abrasive media.
