The silica sand has irregularly particle size, resulting in molds with low permeability and porosity. By the other hand, CastBall is a spherical material with uniform size and shape that maximes the permeability and porosity preventing the occurence of gas-related defects that can weaken the casting strength.
CastBall unique properties allow exceptional benefits in the cores and mold process for metal casting industries reducing costs, improving quality, increasing production, improving healthsafety & sustainability environment.
AL is a white aluminum oxide obtained from the fusion of calcined alumina in electric arc furnaces. It is recommended for refractory applications where purity, chemical stability and high refractoriness are characteristics to be considered.
BT is a brown aluminum oxide obtained from the reduction of high quality bauxite in an electric arc furnace. Due to its high toughness, BT is recommended for use in bonded abrasives (grinding wheels, cutoff wheels, points, etc....), coated abrasives (paper & clothe), blasting abrasives, as well as refractory applications.
Carbosil Metallurgical Silicon Carbide dissociates or sublimates in molten iron and the silicon reacts with the metal oxides in the melt while the carbon provides exothermic energy to the furnace.
MUB-M is a product obtained by the fusion of quartz and alumina in an electric arc furnace. Hardness is slightly lower than the MUB, it also has low thermal expansion and high thermal shock resistance, which makes MUB-M an excellent material for investment casting and other refractory applications.
MUBS is a fused mullite obtained from fusion of silica sand and alumina in an electric arc furnace. It is less pure than MUB but also presents low thermal expansion and high thermal shock resistance that make MUBS an excellent material for investment casting and other refractory applications.
