Black Fused Alumina

Black Fused Alumina

This Black Fused Alumina, also known as low-aluminum corundum, is characterized by low Al2O3 and a certain amount of Fe2O3 (about 10%). It has medium hardness, high thermal stability and high toughness. Black fused alumina is a new type of grinding media for polishing. It has the characteristics of high hardness, strong toughness, good bonding performance, good hydrophilicity, good self-sharpness, smooth surface and high smoothness.

Product description:

This Black Fused Alumina, also known as low-aluminum corundum, is characterized by low Al2O3 and a certain amount of Fe2O3 (about 10%). It has medium hardness, high thermal stability and high toughness. Black fused alumina is a new type of grinding media for polishing. It has the characteristics of high hardness, strong toughness, good bonding performance, good hydrophilicity,  good self-sharpness, smooth surface and high smoothness. It uses bauxite and iron oxide as raw materials and smelts in a tilted arc furnace. Black Fused Alumina is suitable for polishing a variety of spare parts such as bicycles, sewing machines, hard metal tools, medical equipment, watches, glassware and stone grinding. Black Fused Alumina is also the right material for making abrasive tools, so it can be used to make fiber-reinforced cutting wheels, grinding wheels, sandpaper, paper and paste.
