Black Beauty® Iron Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Copper Slag’s bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action, considerably increasing production rates. Copper Slag is ideal for blasting of storage tanks, water towers, bridges, ships, structural & plate steel, offshore platforms, and oil field maintenance.


Black Beauty® Iron Copper Slag’s unique combination of angular shape and bulk density provides fast cleaning performance, which significantly increases production rates versus most subangular or round abrasives.


The low friability of Copper Slag produces less fines after the abrasive impacts the surface, reducing dust levels. Low dust levels improve the operator’s visibility of the work surface, increasing production rates.


Marco has Black Beauty® Iron Copper Slag available from over 20 shipping locations. Marco’s unmatched Copper Slag availability provides quick delivery and reduced freight costs.
