Metal abrasives are mainly made of metals such as steel sand, steel shot, and steel wire cutting shot, and are used for cleaning and strengthening the surface of metals. These metal abrasives have high hardness, strength, and good impact toughness, which can effectively clean the oxide skin, rust, and other dirt on the metal surface during high-speed spraying. At the same time, they increase the roughness of the metal surface and improve the adhesion between the coating or coating and the metal substrate.

Non-Metallic abrasives refer to materials made of non-metallic materials used for grinding, polishing, and grinding. These materials are widely used in the processing and fine processing of materials such as metals, plastics, glass, and stone. There are various types of non-metallic abrasives, including but not limited to copper ore, quartz sand, river sand, brown steel jade, glass beads (glass sand), etc. These abrasives each have their own characteristics and suitable applications, such as quartz sand, which is widely used in sandblasting and grinding operations due to its high hardness and wear resistance.
