Alumina Ceramic Foam Filter

Any project involving the casting of aluminum depends on the quality of the molten metal. The integrity, functionality, and appearance of the finished product can all be seriously harmed by inclusions, contaminants, and trapped gases. Alumina ceramic foam filters, sometimes referred to as ceramic filters for foundries or aluminum casting filters, provide a dependable and effective way to produce cleaner aluminum castings.

  • Superior dimensional tolerances.
  • Stable in the chemical property.
  • Improve microstructure
  • Excellent filtration efficiency.
  • Good in mechanical strength.
  • Resistant to corrosion and thermal shock

Alumina ceramic foam filters come in a range of porosities, measured in pores per inch (PPI). Higher PPI filters offer enhanced filtration efficiency for capturing finer particles, while lower PPI options prioritize faster flow rates.

Here’s a quick overview of the typical performance specifications of alumina ceramic foam filters:

  • Porosity: 80% ~ 90%
  • Working Temperature: ≤ 1200°C (2192°F)
  • Volume Density: ≤ 0.5 g/cm³
  • Compression Strength (Room Temperature): ≥ 1.0 MPa (145 psi)
  • Thermal Shock Resistance: 800°C to room temperature, 5 cycles

Ceramic filter for casting manufacturers can also provide customized filter sizes and shapes to accommodate specific casting applications.

Applications of Alumina Ceramic Foam Filters

Many different aluminum casting applications use alumina ceramic foam filters, such as:

  • Aluminum profile production: These filters guarantee the structural integrity and smooth surface finish needed for extruded items such as window frames and architectural profiles.
  • Aluminum foil production: Alumina ceramic foam filters are good at removing contaminants that uniform the thickness and produce high-quality optimal heat for food packaging.
  • Aluminum alloy casting: Aluminum casting filters ensure minimal casting flaws and a cleaner metal flow during the production of engine blocks, wheels, and other intricate components.

Manufacturers of ceramic foam filters also provide versions that are appropriate for filtering other molten metals, like bronze and magnesium, in addition to aluminum.

Advantages of Alumina Ceramic Foam Filters

There are several benefits that alumina ceramic foam filters offer over conventional filtration techniques.

  • Superior Filtration Efficiency: The highly porous structure of these filters’ efficiently eliminates big inclusions and catches micron-sized particles that result in much cleaner molten metals,
  • Better Casting Quality: Improved mechanical characteristics and smooth surface finish in the final casting are easily achieved with the help of these Alumina ceramic foam filters as they provide a finer microstructure by removing impurities and trapped gases.
  • Increased Yield Rate: Reduced casting flaws result in a greater yield rate of useable castings, which reduces waste during production and maximizes resource use.
  • Production Process Simplified: These alumina ceramic foam filters feature a plug-and-play setup and have quick integration into the current foundry operations which helps you speed up the production cycle.

Features of Alumina Ceramic Foam Filters

The exquisite craftsmanship of alumina ceramic foam filters results in remarkable performance:

  • Accurate Dimensional Tolerances: Our filters are made with strict tolerances in order to avoid bypasses and preserve constant filtration, and also to guarantee a precise fit inside the filter box.
  • Stable Chemical Properties: These filters possess exceptional chemical resistance to molten aluminum as they are made out of high-purity alumina (aluminum oxide). This feature keeps the filter clean and intact during the casting process.
  • Superior Mechanical Strength: Despite the porous nature of the Alumina ceramic foam filters, they have exceptional mechanical strength, that enables them to endure the pressure and heat requirements of molten metal casting.
  • Thermal Shock Resistance: These filters guarantee a dependable operation in conditions with high temperatures used in foundries as they are crafted to withstand sharp temperature changes without breaking down or deteriorating.
  • Beveled Edges and Compressible Gasket: Efficient filtration and reduced leakage is ensured by the compressible gaskets and beveled edges by creating a tight seal inside the filter box.
