Characteristics of White Fused Alumina Grit
Sharp grains, ideal for applications requiring aggressive cutting
White Fused Alumina Grit consists of angular abrasive grains produced through crushing and screening processes.
During grinding or blasting, the grains exert a significant cutting action upon contact with the workpiece surface, making the material suitable for rapid stock removal, surface cleaning, or surface conditioning.
Flexible grit size range to suit various processes
White Fused Alumina Grit is not limited to a single, fixed specification.
Different grit sizes cater to specific processing requirements:
Coarse grits are suitable for material removal, rough grinding, and surface treatments requiring strong impact.
Medium grits are used for general grinding, surface conditioning, and the manufacture of certain abrasive tools.
Fine grits are ideal for precision grinding, surface finishing, and applications demanding superior surface quality.
Hengtium offers White Fused Alumina abrasives in grit sizes ranging from F12 to F240
If you already have specific grit standards-such as FEPA, JIS, GB, or specifications from a current supplier-simply provide them, and we can verify compatibility with your requirements.
Product Applications
Abrasive Tool Manufacturing
White Fused Alumina Grit serves as an abrasive medium for manufacturing resin-bonded and vitrified grinding wheels, cutting discs, abrasive belts, sandpaper, and other coated or bonded abrasives.
The choice of grit size depends on factors such as the bonding agent, workpiece material, grinding speed, and final surface finish requirements.
Different grit sizes are required for precision grinding versus heavy-duty rough grinding.
Precision Surface Finishing
Suitable for stainless steel parts, aluminum alloy components, precision mechanical parts, molds, castings, and tools.
Its clean, white appearance and high purity offer distinct advantages in surface finishing applications where the introduction of color contamination must be avoided.
Sandblasting
It is suitable for fine sandblasting and surface pre-treatment.
Surface finishes can be controlled by selecting the appropriate grit size.
Applications include removing light oxide layers, surface cleaning, pre-coating preparation, surface roughening, and enhancing surface appearance.
For materials sensitive to surface cleanliness-such as stainless steel or aluminum alloys-this product from Hengtium is a superior choice compared to standard abrasives that contain higher levels of impurities.
Precision Casting
In precision casting processes, White Fused Alumina Grit is used for surface cleaning and related abrasive applications.
The selection of grit size for removing casting residues depends on the workpiece dimensions and surface finish requirements.
Excessively coarse grit may cause unwanted surface damage, while grit that is too fine may reduce processing efficiency.

Production Process
High-Temperature Electric Arc Furnace Smelting
White Fused Alumina grit is produced using high-purity alumina raw materials, smelted at temperatures exceeding 2,050°C.
Upon melting, a stable corundum crystal structure forms, providing the foundation for the material's hardness, wear resistance, and high-temperature performance.
Cooling, Crystallization, and Crushing
After smelting, the material undergoes cooling and crystallization, followed by crushing tailored to the intended application.
Particle shape and size must be strictly controlled during crushing to minimize the formation of non-compliant, irregular particles. Since particle shape directly impacts cutting efficiency and surface finish quality, this stage requires precise handling.
Magnetic Separation
The crushed white fused alumina undergoes magnetic separation to remove magnetic impurities as thoroughly as possible.
This step is crucial for customers requiring high material purity, such as those involved in precision grinding, stainless steel processing, and specific surface treatment applications.
Fine Screening and Grading
Materials are processed through screening and grading to separate them into specific grit sizes (e.g., F24, F36, F46, F60, F80, F120).
This process minimizes the inclusion of oversized or undersized particles, ensuring the final product meets your specific size requirements.
