5 FAQs of Good 99% min 2um~2.7um Aluminium Oxide Powder Al2O3 Alumina for Grinding and Polishing

What is this aluminum oxide powder?
This is fine white powder. It’s aluminum oxide, called alumina. The chemical formula is Al2O3. We make it pure. It measures 99% minimum purity. The particle size is very fine. It ranges between 2 microns and 2.7 microns. People use it mainly for grinding and polishing jobs.

Why choose this specific grade?
Its high purity matters. 99% min purity means few impurities. Impurities can cause scratches. Fine scratches ruin surfaces. The controlled particle size is critical too. Particles between 2um and 2.7um work well. They remove material efficiently. They leave a smooth finish. This grade gives consistent results. It’s reliable for precision work.

How do I use this alumina powder?
You mix it with water or oil. It forms a slurry. The slurry consistency depends on your task. Apply the slurry to your polishing wheel or lap. Use it on metals, ceramics, or glass. Follow your machine’s speed settings. Apply steady pressure. Test on scrap material first. Find the best mix and pressure for your job.

How should I store this powder?
Keep the bag tightly sealed. Store it in a cool place. Keep it dry. Moisture makes the powder clump. Clumps are hard to break up. Clumps ruin the slurry. Avoid storing near heat sources. Heat can degrade performance. Use the powder within its shelf life. Check the expiration date on the bag.

What does the particle size mean?
Particle size means how small the grains are. We measure it in microns (um). One micron is very small. This powder has grains between 2um and 2.7um. Smaller grains cut finer. They make smoother surfaces. Bigger grains cut faster. They remove more material. This specific size range balances cutting speed and finish smoothness. It works for many fine grinding and polishing steps.
