Rust removal abrasives are specialized materials designed for metal surface treatment, primarily used to eliminate rust, oxide layers, and old coatings. Common types include steel shot, steel grit, brown fused alumina, and quartz sand, known for their high hardness, strong cutting ability, and recyclability. These abrasives work by high-speed projection or mechanical friction to clean and roughen metal surfaces, creating an ideal substrate for subsequent processes like painting or electroplating.

Key applications include:

• Steel structure treatment: Surface derusting for bridges, ships, and storage tanks
• Automotive manufacturing: Pretreatment for car bodies and components
• Equipment maintenance: Machinery refurbishment and upkeep
• Foundry industry: Casting cleaning and surface finishing

The selection of rust removal abrasives depends on workpiece material, rust severity, and process requirements. For instance, steel grit suits heavy-duty derusting, while quartz sand is better for fine treatment. Their efficiency, eco-friendliness, and cost-effectiveness make them essential in industrial surface preparation.
