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

The Ceramic Foam Filter from Jiangxi Jintai Special Material Co., Ltd. is a porous, refractory ceramic structure designed for molten metal filtration in foundry applications. It is manufactured using high-purity alumina and zirconia-based formulations, with pore densities ranging from 10 to 30 PPI as confirmed in the product listing. The filter retains structural integrity at temperatures up to 1400°C and is compatible with aluminum, iron, and copper alloys. Its open-cell foam architecture enables high flow rates while trapping non-metallic inclusions, reducing casting defects such as pinholes and slag entrapment.

Typical bulk density for this class of ceramic foam filter is 0.2 to 0.4 g/cm³, and thermal shock resistance is standard in industrial-grade variants. The filters are not coated or impregnated, relying on inherent ceramic porosity for filtration. Commonly used in gravity and low-pressure casting, they are produced without binders or organic additives, ensuring no residue contamination in the melt. The material composition aligns with ISO 13738 for refractory ceramic filters used in non-ferrous casting.

Foundries in the automotive and aerospace sectors source these filters to improve yield rates and reduce post-casting machining. Buyers typically order in bulk quantities of 500 to 2000 units per shipment, packaged in individual cardboard sleeves with moisture-resistant outer cartons. Trade terms are available on request, including FOB Shanghai and CIF ports. Lead time and minimum order quantity must be confirmed directly with the supplier, as these are not specified in the listing.
