Shot blasting is a surface treatment process used in various industries to clean, polish, and prepare surfaces for further processing. Shot blasting is performed by propelling abrasive materials at high velocity onto a surface using compressed air or mechanical devices. The abrasive media used in shot blasting can be made from various materials such as metal, glass, and mineral abrasives. In this article, we will discuss six types of shot blasting grit: brown-fused alumina, chilled iron, garnet mesh, glass bead, high-carbon steel shot, and black silicon carbide.

Brown-fused alumina is a tough, sharp, and hard abrasive material with high thermal conductivity. It is made by fusing bauxite in an electric arc furnace. Brown-fused alumina is used for surface preparation, deburring, and cleaning of metal surfaces. It is also used for cutting and grinding applications.

Chilled iron is a sharp and angular abrasive that is made by chilling cast iron shots. It is used for shot peening, surface preparation, and cleaning of metal surfaces. Chilled iron is suitable for use in a range of industries, including automotive, aerospace, and foundry.

Garnet mesh is a natural mineral abrasive that is environmentally friendly and non-toxic. It is produced by crushing and processing garnet rocks. Garnet mesh is used for surface preparation, cleaning, and finishing of metal surfaces. It is also used for waterjet cutting applications.

Glass bead is a spherical abrasive material made from soda-lime glass. It is used for peening, cleaning, and finishing of metal surfaces. Glass bead is suitable for use in a range of industries, including aerospace, automotive, and medical.

High-carbon steel shot is a hard and durable abrasive material made from high-carbon steel. It is used for surface preparation, cleaning, and deburring of metal surfaces. High-carbon steel shot is also used for peening applications.

Black silicon carbide is a hard and brittle abrasive material that is produced by fusing quartz sand and petroleum coke in an electric arc furnace. It is used for grinding, polishing, and surface preparation of metal surfaces. Black silicon carbide is also used for cutting and slicing applications.

In conclusion, shot blasting is a vital process for preparing and finishing metal surfaces. The abrasive media used in shot blasting can vary, depending on the application requirements. The six types of shot blasting grit discussed in this article: brown-fused alumina, chilled iron, garnet mesh, glass bead, high-carbon steel shot, and black silicon carbide, are all suitable for different applications in various industries. Choosing the right abrasive media is crucial for achieving the desired surface finish and maintaining the integrity of the surface being treated.
