White corundum is widely used in the polishing industry, as its polishing properties offer advantages and characteristics that other abrasives do not possess. Such as low usage amount, fast speed, and short processing time, etc. Of course, the ability of white corundum to possess these characteristics is determined by its properties. So, which specific properties are it that enable white corundum to excel in the polishing industry? 1. High hardness: It can also be used to polish high-hardness workpieces in order to remove dirt and rust from their surfaces ； 2. High purity: Over 99% of white corundum is aluminum oxide, with very few impurities; as a result, it does not react with the workpieces being processed. For those workpieces that cannot come into contact with iron ions, white corundum is an excellent choice! 3. Pure white color: Since it has no other colors, there is no need to worry about the processed parts being stained and affecting their appearance during processing. There are many applications for emery in polishing – from valuable gold jewelry, gems, crystals, and agates to common materials such as copper, aluminum, and plastics. Fine-grit emery is even known as the tool of choice for polishing. As for the price of white corundum polishing powder, it varies depending on the specifications; generally, the price of fine white corundum powder is slightly higher due to the more complex processing procedures and resulting higher costs. Other price ranges should be similar; currently, the approximate range for white corundum is between 3,900 and 6,000, with more expensive varieties costing over 10,000 as well. Specific details need to be discussed with the collector.
