Ebonygrit - Copper Slag

A High Density Blasting Slag
Ebonygrit is produced from a by-product of the manufacturing of copper, which is processed into an abrasive by Opta Minerals. Typically it is composed of ferrosilicate (Fayalite, Fe₂SiO₄) material and oxides, formed when the molten slag is quenched in cold water. This cooling process fractures the slag into coarse and angular particles, making it an ideal blasting slag with optimal blasting properties.

Available sizes and uses:
#EG 12 - provides 3.5-5.0 Mil profile*
The ultimate size for the tough heavy duty blast job on Ships, Bridges, Tanks, Rail Cars, etc.
Suitable for removal of thick, tough old paint, heavy rust and for achieving a coarse profile.
#EG 14 - provides 2.8–4.0 Mil profile*
An All-Purpose size for structural steel, bridges, tanks, ships, watertowers etc.
#EG 20 - provides 1.5–3.0 Mil profile*
A utility size for all kind of blasting jobs. Suitable for the removal of light rust and paint and mill scale.
