Product Description Foam Ceramic are mainly used for filtration of aluminium and aluminium alloys in foundries and cast houses .With their excellent thermal shock resistance and corrosion resistance from molten aluminum,they can effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit. SIC Ceramic Foam filters are just developed as a new type molten metal filter to decrease casting flaw in recent years.With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance,erode resistance, high-performance,SIC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.Physical Properties for Silicon Carbide Ceramic Foam Filters:Working Temperature≤1540°CPorosity80~90%Compression Strength (Room Temperature)≥1.0MpaVolume Density0.3-0.5g/cm3Thermal Shock Resistance1200°C---room temperature 3 timesApplicationcast iron, cast copper, cast bronze, cast brasshigh temperature gas filter,chemical fillings and catalysis carrier etc. Chemical Composition for Silicon Carbide Ceramic Foam Filters:Al2O3SiCSiO2Fe2O3≤28.00%≥62.00%≤10.00%≤0.50% Silicon Carbide Ceramic Foam Filters regular sizes:Round shape40x11mm, 40x15mm, 50x15mm, 50x20mm, 60x22mm,70x22mm, 80x22mm , 90x22mm,100x22mm, 305x25mm Square shape40x40x11mm, 40x40x15mm, 50x50x22mm, 75x75x22mm, 50x75x22mm, 100x75x22mm, 100x100x22mm, 55x55x15mm, 150x150x22mmOther sizes can be customizedPhysical &chemical properties for 3 kinds of ceramic foam filter TypeCeramic Ceramic FilterMaterialAluminaSilicon carbideZirconiaApplied temperature≤1200celsius degree≤1500celsius degree≤1700celsius degreeColorWhiteGrey blackYellowBulk Density0.35~0.55g/cm30.45~0.65g/cm31~1.5g/cm3Bore Density10~60PPI10~60PPI10~60PPIPorosity80~90%80~90%80~90%Bending Strength0.6Mpa0.8Mpa0.8-1.0MpaCompression Strength≥0.8Mpa≥1.0Mpa≥1.5MpaThermal Shock ResistanceNot break after 6 times thermal shock testingApplicationMolten Aluminum and AlloyMolten Iron and AlloyMolten Stainless Steel, Alloy and other metal in precision moldingFUNCTIONCeramic foam is a new industrial ceramic products with low bulk density (0.25 ~ 0.65) g/cm3, high porosity (60% ~ 90%), andthree-dimensional reticulated structure. As ceramic foam has excellent properties such like: high temperature resistance, strongchemical corrosion resistance, and large surface area as a result of high porosity, it is widely used in molten metal filtrationto remove undesirable nonmetallic inclusions in the melt.
