Product DescriptionProduct DescriptionHigh-Performance Alumina Ceramic Foam Filter PlatesOur Alumina (Al2O3) Foam Ceramic Filters are a new type of highly efficient filtration material, manufactured using the unique organic foam impregnation method. They feature a high open porosity, a three-dimensional skeletal network, and a uniform pore size distribution. Primarily used in the non-ferrous metal casting industry, especially for aluminum and its alloys, these filters effectively remove oxides, inclusions, and entrapped gases from the molten metal, significantly enhancing the purity, mechanical properties, and surface quality of the final castingsSpecificationAlumina Ceramic Filter AdvantagesExcellent Thermal Shock Resistance: Maintains structural integrity and resists cracking even when subjected to the instantaneous thermal impact of high-temperature molten metal.High Chemical Stability: Does not chemically react with molten aluminum, ensuring zero secondary contamination during the filtration process. Highly Efficient Impurity Removal: The 3D interconnected network structure utilizes multiple mechanisms—flow rectification, mechanical interception, and "filter cake" adsorption—to achieve high filtration efficiency.Improved Casting Quality: Effectively reduces porosity and slag inclusion defects, leading to a more uniform and dense casting structure, thus improving elongation and tensile strength.Low Pressure Drop & High Flow Rate: The high open porosity and interconnected pore structure ensure smooth, fast passage of the molten metal, boosting production efficiency.Products UsageSelection of pore size: When using a filter, the pore size of the filter (number of pores per inch of product, PPI) must be determined based on the casting material, casting size, pouring temperature, and the number of inclusions in the molten metal; The pore diameters are mainly: coarse pores (10PPI, 15PPI), intermediate pores (20PPI), and fine pores (25PPI, 30PPI). Ductile iron parts generally use 10 PPl or 15 PP products, gray iron and copper castings generally use 15 PPI or 20 PPI products, and aluminum alloy castings generally use 20 PPI or 30 PPI products.Size selection: The greater the thickness of the foam ceramic filter, the better the strength of the filter and the higher the filtration efficiency of the filter, but the higher the cost of use. Considering the most suitable strength and filtration efficiency, the general recommendations are as follows: Size: 40MM~75MM, Thickness: 15MM~22MM Size: 75MM-120MM, Thickness: 22MM~25MM Size: 120MM~150MM, Thickness: 25MM~30MM Size: > 150MM, thickness 30MM~40MMFiltration capacity: The filtration capacity per unit area of the filter generally does not exceed: gray cast iron 1.5-2kg/cm2, ductile iron 1-1.5kg/cm2 (due to differences in casting system processes, try to design with the lower limit value to increase the insurance factor) .Filter area: The cross-sectional area of the sprue where the filter is placed should be appropriately expanded. Generally, the cross-sectional area of the normal sprue is 2 to 4 times.Placement location: The foam ceramic filter can be placed in various parts of the pouring system. It should be selected according to the characteristics of the parts and production conditions, and should be as close as possible to the casting to achieve the best filtration effect. In practical applications, according to different castings and requirements.ApplicationsAluminum and Aluminum Alloy Casting: Widely used for melt purification in the production of high-precision aluminum alloy castings such as profiles, plates, foils, automotive wheels, pistons, and engine blocks.Low-Pressure and Differential Pressure Casting: Especially suitable for precision casting processes that demand high quality.Other Non-Ferrous Metals: Can also be used for purifying zinc, magnesium, and their respective alloys.Physical and Chemical IndexMaterialAlumina/ALOSilicon carbide/SICZirconia/ZrOColorWhiteGrayYellowPore Density8-60ppi8-60ppi8-60ppPorosity80-90%80-90%80-90%Refractoriness≤1100oC≤1500oC≤1700oCFlexure Strength>0.6Mpa>0.8Mpa>1.0MpaCompressive Strength>1Mpa>1Mpa>1.5MpaDensity0.3-0.48g/cm30.35-0.5g/cm30.9-1.5g/cm3Resistance to Heat Shocks6times/1100oC6times/1500oC6times/1700oCApplicationAluminum alloys And Others Nonferrous Metal Alloys.Nodular Cast IronMalleable Cast IronGray And Other Cast IronMetal Alloys with High Melting Points, Such As SteelAlloy SteelStainless SteelDrawings & DimensionsAvailable in various shapes (square, round, etc.) and different pore sizes (PPI - Pores Per Inch), typically ranging from 10 PPI to 60 PPI, to meet diverse flow rate and filtration precision requirements.Please contact us for more information.Company ProfileQingdao TTWY International Trade Co., Ltd https://ttwymachinery.en.made-in-china.com/Our company specialized in producing casting equipment.
