Import Ceramic Honeycomb Filter — Buy in Bulk from Supplier in China

King Filter Engineering Co., Ltd. produces a ceramic honeycomb filter made from mullite, manufactured in China. The filter contains 50 % Al₂O₃, offers square, round or triangle hole types, and features millihole apertures of 2 - 3 µm. Its coefficient of thermal expansion is listed as less than 4.0 × 10⁻⁶ K⁻¹ and it can withstand temperatures up to 1700 °C. Formal sizes are supplied as 50 × 50 × 12.5 mm, 50 × 75 × 12.5 mm or 100 × 75 × 12.5 mm, with the option for custom dimensions.

Mullite filters are standard in foundry applications for iron, copper and steel casting because of their high refractoriness and mechanical strength. Typical porosity for such filters ranges from 80 % to 90 %, providing efficient capture of large oxide particles while allowing a laminar flow that reduces turbulence. Industry data shows a bending strength at room temperature often exceeding 20 MPa, which aligns with the product’s intended use in harsh thermal cycles. The filter’s fine millihole structure also helps trap microscopic impurities that can affect metal quality.

Potential buyers should confirm the exact hole geometry required for their casting line and request a test report confirming the 1700 °C refractoriness. Shipping is usually arranged with standard export packing, and the supplier can adapt size specifications to match equipment interfaces.
