Polishing Alumina Powder Supplier for Precision Surface Finishing
Why is aluminum oxide suitable for polishing?
Alumina (α-Al₂O₃) (corundum crystal form) has a Mohs hardness of 9, second only to diamond and silicon carbide. This allows it to effectively remove even tiny surface protrusions during polishing, achieving highly efficient grinding. Furthermore, compared to diamond, its hardness is moderate, preventing excessive scratching of the workpiece, making it ideal for fine polishing and final polishing. KOSNANO’s polishing alumina is produced through process control to achieve varying crystal forms and particle size distributions. This allows it to meet the needs of various polishing stages, from rough grinding to fine polishing.
Our company offers alumina polishing compound in a variety of particle sizes, ranging from 50nm to 1 microns. These powders can be used for various applications,our products including :
polishing compound for metal ; stainless steel mirror polishing, titanium polishing, cast iron polishing, aluminum mirror polishing, marble mirror polishing, paint polishing, resin polishing, PCB polishing, glass polishing, optical glass polishing, eyeglass lens polishing, resin lens polishing, sapphire polishing, LED polishing, germanium polishing, and zinc polishing. Our products offer fast polishing, excellent brightness, and scratch-free finishes.
