Ceramic coated calcined and blue fired brown aluminum oxide abrasive grains enhance toughness, surface roughness, and binder adhesion, improving cutting efficiency and wheel durability.
Ceramic coated calcined brown aluminum oxide and Ceramic coated blue fired aluminum oxide are both Ceramic coated Brown fused alumina abrasive grains. They are processed from tilting furnace brown aluminum oxide as raw material. The calcination process can reduce the impurity content and dust of brown aluminum oxide. It can also perform high-temperature shaping on the cracks generated during the crushing process of BFA. The ceramic coating process can improve the toughness, hydrophilicity, and surface roughness of abrasive particles, increase the holding force of binders on abrasive particles. As a result, it improves cutting efficiency and applicability time after making grinding wheel products.
Superior performance in processing hard materials like metals, ceramics, and stones.
Improves the stability and durability of the product under thermal stress..
Reduces the risk of cracks and deformation in high-temperature environments.
Long-lasting performance in abrasive applications such as blasting and surface finishing.
