💬 Frequently Asked Questions
Q1: What is the main difference between white fused alumina powder and grain?
White fused alumina powder has a much finer particle size and is mainly used for polishing and precision grinding, while the grain type is used for sandblasting or surface roughening.
Q2: Can it be used in electronic component polishing?
Yes. Its high purity and non-conductive nature make it ideal for polishing semiconductors and precision parts without introducing contamination.
Q3: How is the particle size controlled?
The powder is screened and classified using advanced sieving and air-jet milling systems to ensure a narrow and consistent particle size distribution.
Q4: What packaging options are available?
Standard packing is 25 kg kraft paper bags or 1-ton jumbo bags. Moisture-proof and vacuum-sealed packaging options are available for high-purity grades.
