We know exactly what a leap a pure, sharp, and durable White Fused Aluminum Oxide can bring to your production process. Today, we are proud to introduce our star product – Shengguang Guanghe White Fused Aluminum Oxide.
Why White Fused Aluminum Oxide is the Preferred Choice for High-End Manufacturing?
White Fused Aluminum Oxide is produced by fusing high-purity alumina powder in an electric arc furnace at high temperatures and then cooling it. It boasts extremely high purity (Al₂O₃ content ≥99%), dense crystal structure, and a hardness slightly higher than brown fused aluminum oxide. These inherent characteristics endow it with irreplaceable industrial value:
High Hardness & Wear Resistance: With a Mohs hardness of 9.0, second only to silicon carbide and diamond, it maintains lasting cutting ability during grinding and polishing, offers a longer service life, thereby effectively reducing your unit production cost.
Exceptional Cutting Performance: The crystals fracture into sharp, angular shapes upon breaking, acting like countless tiny blades. This enables fast, precise cutting action rather than just peening, making it particularly suitable for applications demanding high surface finish on workpieces.
Outstanding Chemical Stability: Its high purity means it is less likely to react chemically with the workpiece during processing, preventing surface contamination and effectively avoiding iron residue. It is the ideal choice for processing premium metals like stainless steel, titanium alloys, and aluminum alloys.
Good Thermal Stability: Maintains excellent physical properties even at high temperatures, resistant to deformation or softening, ensuring stability under high-speed, heavy-duty grinding conditions.

Is the primary goal material removal? -> Choose coarser grits (e.g., F24-F60), prioritizing cutting speed.
Is the goal to improve surface finish? -> Choose finer grits (e.g., F80-F180), prioritizing surface quality.
Is the goal a mirror finish? -> Must choose micro-powders (W63 and finer).
Step 2: Consider Your Processing Method
Blasting Operations: Consider nozzle diameter and equipment pressure, typically using F16-F80 grit.
Grinding Wheel Manufacturing: The grit size and bulk density must be matched to the wheel's bond (vitrified, resin, rubber) and the grinding process.
Loose Abrasive Grinding (Barrel, Vibratory): Requires grit or fine powder with moderate toughness and good grain shape.
Step 3: Focus on Key Quality Indicators
Chemical Composition (Especially Al₂O₃ Content): Directly determines hardness and chemical stability; higher is better.
Particle Size Distribution: A more concentrated distribution leads to more uniform processing results and controllable surface quality.
Magnetic Content: For stainless steel, titanium alloys, etc., low or non-magnetic products are essential.
Grain Shape: Blasting and loose abrasive grinding benefit from angular grains for strong cutting force; some precision polishing requires more rounded grains.
