Advantages of White Fused Alumina
High-purity Al₂O₃, suitable for impurity-sensitive applications
Compared to brown fused alumina, white fused alumina has a lower impurity content, making it ideal for applications that demand high standards regarding abrasive purity, color, and the cleanliness of the processed surface.
Mohs hardness of approximately 9.0, suitable for high-precision grinding
With a Mohs hardness of approximately 9.0, Hengtium White Fused Alumina is a high-hardness industrial abrasive. It is suitable for machining operations requiring strong grinding capabilities, while allowing for the control of material removal rates and final surface finishes through the selection of different grit sizes.
Product Applications
Precision Grinding
White fused alumina is suitable for applications sensitive to surface finish, material purity, and cross-contamination. Due to its high purity, it facilitates effective contamination control in processes requiring clean machined surfaces.
Precision Components
It is suitable for products requiring superior surface quality-such as bearings, precision mechanical parts, and tools-with specific grit sizes selectable based on the processing requirements.
Grinding Wheels and Cutting Discs
White fused alumina serves as an abrasive for resin-bonded wheels, vitrified wheels, and cutting discs.
Hengtium's product offers distinct advantages in applications demanding high cutting efficiency and a clean surface finish.
Sandblasting and Surface Treatment
Compared to standard fused alumina, this product is ideal for applications with strict requirements regarding surface cleanliness, color, and material purity-such as stainless steel treatment, surface polishing, decorative sandblasting, and pre-coating surface preparation. High-purity white fused alumina is the preferred choice when the final workpiece surface must remain exceptionally clean.

When purchasing white fused alumina, it is recommended that you focus on these key indicators
- What is the Al₂O₃ content?
- What is the controlled level of Na₂O?
- What are the levels of impurities such as Fe₂O₃ and SiO₂?
- What is the Mohs hardness?
- Is the particle size distribution stable?
- Are there significant differences between batches?
- Can you provide test reports and samples?
These specifications will ultimately affect your grinding wheels, cutting discs, sandblasting media, or refractory products.
