Products

Brown Fused Alumina - Macro Grit Brown Fused Alumina is a tough, sharp abrasives which is highly suitable for grinding metals of high tensile strength. Its thermal properties make it an excellent material for use in the manufacture of refractory products. This material is also used in other applications like blasting and surface hardening.
White Fused Alumina - Macro Grit White Fused Alumina is highly friable and hence used in Vitrified Bonded Abrasives products where cool, fast cutting action is essential and also in the manufacture of high purity Alumina refractories. Other applications include use in Coated Abrasives, Surface treatment, Ceramic Tiles, Anti-Skid Paints, Fluidized Bed Furnaces and Skin / Dental Care.
Silicon Carbide - Macro Grit Silicon Carbide is a man made mineral of extreme hardness and sharpness. It is the ideal abrasive for grinding / sanding materials of low tensile strength such as Cast Iron, Brass, Aluminum, Bronze etc. Its thermal properties make it an excellent medium for use in the manufacture of refractory products and crucibles. Silicon Carbide Grains are also used in marble and granite polishing, manufacture of Kiln furniture and as a deoxidizer in Iron and steel making.
Semi Friable Alumina - Macro Grit Semi-Friable Alumina is a low titania containing brown corundum produced by controlled smelting of special grade Bauxite in an electric arc furnace above 2000 deg C. The lower titania gives an intermediate toughness between that of White and Brown Regular corundum and strict control of this parameter over a narrow band ensures consistent quality. In Bonded Abrasives, semi friable alumina can be used in depressed center wheels, cut off Wheels, in Surface and Cylindrical Grinding of heat sensitive metals, alloys etc. The wheels made of this material are made best use of where cool and fast cutting is required. In Coated Abrasives, these grains are best suited for use in metal finishing and for sanding of wood, plastic coatings and paint.
Blue Fired Semi Friable Alumina - Macro Grits Blue Fired Semi Friable Alumina is a low titania containing brown corundum produced by controlled smelting of special grade Bauxite in an electric arc furnace at greater than 2000 deg C. The lower titania and an intermediate toughness between that of White and Brown Regular corundum and strict control of this parameter over a narrow band ensure consistent quality. These grains are best suited for use under extreme grinding conditions where high stock removal efficiency is required. Main uses are in metals especially alloyed steels, non Ferrous metals and alloys of Copper and Zinc.
Fused Mullite - Macro Grits Fused Mullite is one of the main raw materials used by the refractory industry for applications requiring thermal shock resistance and corrosion resistance. CUMI’s Fused Mullite is available in all customer Specified sizes Typical Chemistry Constituent Al2O3 SiO2 Fe2O3 Na2O Value* 78% 21.6% 0.05% 0.35% * As analysed on size -16+30 ASTM sieves
Sintered Alumina - Macro Grits AzureS is a Sintered Alumina abrasives grain. This grade of sintered alumina abrasive grain is well known for its high performance and unique fracture characteristic. It performs better in high pressure grinding application and also withstands other severe application conditions. It also provides cooler cutting and longer life of the wheel. All these make this grain a unique choice for the abrasives manufacturers.
Thermal Spray Powders - Micro Grits CUMI produces Pure Alumina, Alumina – Titania Composite, Pure Titania and Pure Chromia Powders for thermal spray and plasma spray applications.
