Ultrablast is a high-density disposable blasting slag made from a by-product of nickel production. It is an ideal abrasive for general-purpose use, including shipyards, bridges and general industrial blast cleaning. Tests have shown nickel slag to provide high productivity improvements over traditional abrasives.
