• Cast Iron Grits / Chilled Iron Grits

  All Abrasives Industries offer high quality Cast Iron Grits / Chilled Iron Grits that are manufactured by melting cast iron followed by atomisation and grain crushing. Because of extreme hardness, the grains disintegrate into sharp-edged particles during the blasting process, giving rise to grits. These grits then become perfect with high cleaning and roughening properties.

  Our Cast Iron Grits / Chilled Iron Grits are angular in shape and feature a white texture, with a carbon content in excess of 1.7% and up to 3.5%, and hardness above 750 HV/63RC.

  Our Cast Iron Grits / Chilled Iron Grits are best suited to meet the requirements of a variety of customers who need tough and fast cleaning media that produce a sharp and angular profile for use in compressed air powered blast rooms and booths. Our iron grits are perfectly sharp, angular, hard and brittle. They are also reusable, which makes them highly cost-effective.

  Cast Iron Grits / Chilled Iron Grits are ideal for air blast applications requiring an aggressive cutting rate. They are ideally suited for surface preparation prior to the application of metal spray coatings. All Abrasives Industries’ Chilled Iron Grits can also be used as high-density aggregates in ballast applications and for radiation shielding.
