Today, the Company’s range varieties of Abrasives, Ceramics, Refractory products and electro-minerals manufactured across several locations in and outside the country.

Abrasives: An Abrasive is a substance which grinds, cleans, scours, abrades or removes solid material by rubbing action or by impact. Abrasives are mineral like materials available in different shapes, sizes and types according to need. Abrasive materials and Abrasive products are utilized in several end user industries such as manufacture of Machinery, Electrical & Electronic equipment, Transportation and Metal fabrication among others.

Electro Minerals: The major product groups of this segment are Fused Alumina (comprising Brown and White Alumina), Silicon Carbide (crude, macro and fine), Fused Zirconia, Alumina Zirconia, Pearl Zirconia and Zircon Mullite. The Company also manufactures a range of ‘specialities’ like Semi Friable, Azure-S and fine powders for niche markets. The operations are carried out through eight manufacturing facilities located in India, Russia and South Africa.

Industrial Ceramics: The Ceramics product group offers products which harness the heat resistance / containment, wear resistance and insulation properties of ceramics and also corrosion resistance properties of various materials.

Super Refractories: Refractory is a material that will retain its shape and chemical identity when subjected to high temperatures and is used in applications that require extreme resistance to heat, such as furnace linings. Refractory products are basically used in industries for heat resistant and containment. CUMI’s manufactures Super Refractories (which can be in two forms fired refractories and monolithics) and also Refractory Fibre.
