If you're looking to make sandblasted aluminum parts whiter, especially when working with high-alloy steel, it's essential to consider using premium stainless steel media such as stainless steel shot or wire cutting pellets. These materials can significantly improve the surface finish and brightness of the final product.
Here’s some useful knowledge about abrasive consumables used in sandblasting equipment:
1. **Sandblasting Process**: Sandblasting is widely used for a variety of applications, including removing rust from hardware, blasting aluminum alloys, creating a matte finish on glass, deburring plastic parts, achieving a frosted look on acrylics, treating PC and PS surfaces, resin finishing, casting workpiece blasting, zinc alloy surface roughening, blasting stainless steel, stone material treatment, paint removal, welding residue removal, and more. It's a versatile method that can be adapted to different materials and desired finishes.
2. **Acrylic Sandblasting**: When customers request a very foggy or frosted effect, glass sand is typically used. For higher quality and better transparency, white corundum is preferred. If a balance between clarity and texture is needed, glass beads are ideal. Sometimes, a small amount of glass sand is mixed with glass beads to achieve a slightly transparent and smooth finish.
3. **Stainless Steel Sandblasting**: The choice of abrasive depends on the type of stainless steel panel—whether it's polished, brushed, or matte-finished. For a smoother surface, brown fused alumina or white corundum can be used. If a highly smooth finish is required, glass beads or glass sand are recommended. Special requirements may call for a combination of these materials to achieve the best results.
4. **Die-Casting Parts**: These parts often require burr removal, and low-alloy steel shots are commonly used. Cast steel shot or steel balls are effective for minimizing scratches and achieving a cleaner surface. For removing dirt, a mix of steel balls and steel shot is usually recommended. To enhance the whiteness of sandblasted aluminum, high-cost stainless steel shots or wire-cut pellets are suggested. For cost-effective options, a mixture of cast steel beads and non-stop steel shots in an 8:2 ratio can work well. After each blasting session, the steel balls should be cleaned to maintain efficiency and ensure a consistently white finish after multiple passes.
5. **Iron Parts**: When blasting iron components, the main goal is to remove oxidation layers and rust. This process also helps eliminate sharp edges. Some applications use low-alloy steel abrasives, while others apply them after sanding. Brown fused alumina and white corundum are popular choices, depending on color preferences and budget constraints.
In general, for steel structures, steel plates, and other metal surfaces requiring rust removal, cost-effective options like white corundum or natural garnet sand can be used to achieve the required SA2.5 surface preparation standard.

The excellent softness and sharpness of the flexible grinding wheel make it particularly suitable for curved surface processing. While it has sufficient grinding capacity, it also has the same finishing and polishing capabilities as sandpaper discs. This type of grinding wheel has good durability and cost-effectiveness. The flexible substrate and rubber can prevent vibration from being transmitted to the hands of the operator, thereby reducing fatigue. Because rubber is used between the grinding wheel and the base, the absorption capacity is higher than that of traditional paper flaps or flexible grinding wheels, and dust, dust, noise and vibration are extremely low. In addition, the flexible grinding wheel has high structural strength and hardness, good wear resistance, and can grind and polish the workpiece according to the deformation of the workpiece, ensuring the surface quality and contour accuracy and consistency of the workpiece12.
Compared with traditional grinding wheel grinding, flexible belt grinding also has the advantages of simple equipment, easy operation, large grinding ratio and good surface quality.
