亚白刚玉是在高品质棕刚玉基础上生产的，由于其化学成份和物理性能均与白刚玉接近，故称之为亚白刚玉。该产品具有白刚玉的硬度，同时兼有棕刚玉的韧性，是理想的高级耐火材料，用其替代致密刚玉制成的铁沟浇注料以及替代白刚玉、板状刚玉制作的滑板、刚玉砖、耐磨浇注料等，均取得与使用致密刚玉和白刚玉等相当的效果，是一种优质的耐火原料。
Vice-white fused alumina is made on basis of high quality brown fused alumina. It is close to the white fused alumina in the chemical composition and physical properties. With the hardness of white fused alumina and toughness of brown fused alumina, it is a perfect high-class refractory material, applied in iron ditch castables instead of dense fused alumina and sliding plates, corundum bricks and wear-resistant castables instead of white fused alumina with the equivalent effect
