Ebony Grit Copper Slag Abrasive

Prices listed are base rates only and total cost vary depending on shipment. Most abrasives can only be shipped via LTL Truck Freight due to the heavy weight of the product. Please call our office at (405)235-1387 for accurate pricing and shipping details.

 

Ebony grit 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 Ebony Grit 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.

Ebony grit 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, angular particles, making it an ideal blasting slag with optimal blasting properties.

ADVANTAGES OF 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%

"In some cases the reduction in dust has been at least 70%... The productivity increase has been in the area of 60% faster..." - Decker Inc./Echo Bridge Inc.
