Ebonygrit – Copper Slag
MSDS and Technical Data Sheet available on request.
Ebonygrit is produced from metallurgical slags and provides fast blast cleaning rates. Three grades are available to suit most common blasting operations. The hardness and high density of EbonyGrit gives it a high resistance to fracture with low dust formation during blasting as well as faster blast production rates when compared to local slag abrasives. This abrasive is commonly used for restoration of heavily painted steel bridges, ships and water towers. Ebonygrit is a disposable high-density blasting slag made from a by-product of copper production. 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.

Advantages of Ebonygrit – Copper Slag
Due to high density, Ebony Grit distinguishes from light weight blasting slag
- Very high cleaning speed
- Very low dust level
- Lower abrasive consumption
- Crystalline silica levels are less than 1%
