White corundum is made by melting high-quality processed alumina in an electric arc furnace. Compared with brown corundum, it has higher hardness and slightly lower toughness. In addition, it also has the characteristics of high purity, good self-polishing performance, excellent cutting performance, low heat generation and high efficiency.
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.
