Brown Fused Alumina Refractory
Product Description
Brown Fused Alumina is a versatile abrasive material used in applications such as sandblasting and cutting. Its high hardness and durability make it ideal for removing surface coatings, preparing surfaces for painting or treatments, and roughening or cleaning surfaces to improve adhesion and enable further processing in various industries. It is also utilized in refractory materials for lining furnaces and high-temperature equipment, owing to its elevated melting point and resistance to thermal shock.
