铬刚玉是以氧化铝粉为主要原料，适配氧化铬等，经高温熔炼而成，呈粉红色及深红色。硬度与白刚玉相似，韧性比白刚玉高。铬刚玉结晶度好、颜色纯正、杂质少、粒度组成均匀、磁性物含量低、堆积密度高、韧性值高，深受国内外的用户好评。

Chromium corundum is produced by melting aluminum oxide powder—with the addition of chromium oxide and other components—at high temperatures, resulting in a pink or deep red color. It has a hardness similar to that of white corundum but exhibits greater toughness. With its high crystallinity, pure color, low impurity content, uniform particle size distribution, low magnetic content, high bulk density, and high toughness, chromium corundum has earned widespread acclaim from customers both domestically and internationally.

其用于特殊高温耐火材料领域，其耐高温性能高于白刚玉和棕刚玉。用其制造的磨具，耐用度好，磨加工光洁度高。适用于量具、机床主轴、仪表零件、螺纹工件及样板磨等精细磨削。

It is used in the field of special high-temperature refractory materials, and its high-temperature resistance exceeds that of white and brown fused alumina. Abrasives manufactured from this material offer excellent durability and produce a high surface finish. They are suitable for precision grinding applications such as measuring tools, machine tool spindles, instrument components, threaded workpieces, and template grinding.

铬刚玉类材料同样可用于涂附磨具生产工业，主要用于木材的打磨，同样也可进行有色金属的研磨，如铜、黄铜等金属，与白刚玉相比，铬刚玉更不易碎，因此形成其平滑的表面。

Chromium corundum materials are also used in the production of coated abrasives, primarily for sanding wood, though they can also be used for grinding non-ferrous metals such as copper and brass. Compared to white corundum, chromium corundum is less prone to breakage, which helps produce a smooth surface.
