Alumina is suitable for a variety of dry and wet treatment process, it can be use for  any workpiece rough surface to be polished fine, is one of the most economical and  practical  abrasive. This kind of artificial synthetic abrasive with sharp water-caltrop has second hardness  only after diamond, and it is especially suitable for using when the iron pollution is strictly required. For the roughest cutting, it also can be made of pebbles to apply on dealing with  workpiece with precision  sizese to make it  achieve a very low roughness. Because of its high density, Sharp, diamond structure, it is one of the fastest cutting abrasives. 

Alumina is used to make brown corundum by electrically melting high-quality bauxite, while high-quality aluminate is used to make pink corundum and white corundum. Their natural crystal structure makes them high hardness and fast cutting performance. At the same time, they are often used as the raw materials for bonding and coating abrasives.

 Alumina can be recycled many times, the number of cycles  have to do  with material grade and specific process, most of the standard abrasive blasting equipment can be used. 

Applicable Industry: Aerospace Industry, automobile industry, consumer goods processing, Casting/die Casting, OEM distributors, semiconductor industry and other different fields.

Applicable technology:  Surface electroplating, painting, glazing and polytetrafluoroethylene pretreatment;  and aluminum and  its alloy products deburring; mold cleaning; pre-treatment before metal blasting; dry and wet grinding; precision optical refraction; minerals, metals, grinding of glass and crystals;  Glass Engraving and paint additive.

磨料氧化铝
氧化铝适用于多种干湿处理工艺，可将任何工件的粗糙表面打磨精细，
是最经济实惠的磨料之一。这种尖锐有菱角的人工合成磨料具有仅次于金刚石的硬度，尤其适合对铁质污染有严格要求时使用。用于最粗糙的切割，也可制成卵石形对尺寸精密的工件进行处理，来达到极低的粗糙度。由于它的高密度、尖锐、菱 角结构，因此它是最快速的切割磨料之一。
氧化铝通过电熔高质矾土矿来制造棕刚玉的，而高质铝酸盐用来生产粉刚玉和白刚玉。它们的天然晶体结构使其硬度高，切割性能快。同时它们经常用作固结磨具和涂附磨具的原料。
氧化铝可多次循环利用，循环次数和材料等级及具体工艺过程有关，大多数标准磨料喷砂设备均可使用。
适用工业范围：航空航天业、汽车业、消费品加工、铸造/压铸、OEM分销商、半导体工业等不同领域。
适用工艺范围：表面电镀、油漆，上釉和涂装聚四氟乙烯前的预处理；铝和合金制品去毛刺，去锅垢；模具清理；金属喷砂前预处理；干磨和湿磨；精密光学折射；矿物质，金属，玻璃和晶体的研磨；玻璃雕刻和油漆添加剂。
