ALODUR®
ALODUR
We are the world’s largest producer of fused alumina, also known as fused aluminum oxide. Since production started in 1943 in Villach, Austria, we have expanded to 12 production sites for aluminum oxides worldwide, making us the market leader in this industry, selling under the well-known brand and industry-standard ALODUR.
It is manufactured by smelting calcined bauxite in electric arc furnaces by electrothermal fusion at temperatures of around 2000°C. The result is a synthetic hard mineral with a value of 9 on the Mohs scale of hardness, placing it close to diamond (Mohs 10), the hardest known substance.
Besides its superior hardness, the characteristics of ALODUR includes sharp-edged grains, great load bearing capacity, a high degree of physical resistance and thermal and chemical stability. This makes ALODUR extremely well suited for use in many different industries such as abrasives, refractories, sandblasting etc. Fused aluminum oxide grits are put to use in grinding, machining, blasting, cutting operations and for the production of shaped bricks or unshaped refractory concretes and plastics.
