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

The Alumina Ceramic Foam Filter from Univeternity Machinery Co., Ltd. is engineered for molten metal filtration in aluminum and alloy production. It features high porosity to maximize flow rates while capturing inclusions, with thermal stability that withstands casting temperatures. The filter’s open-cell structure ensures uniform metal distribution and reduces turbulence during pouring, which improves the mechanical properties of the final castings.

Manufactured from high-purity alumina, these filters resist chemical corrosion from molten alloys and maintain dimensional integrity under thermal cycling. Typical industry grades for such filters include 85 to 99 percent alumina content, with pore sizes ranging from 10 to 30 PPI (pores per inch) as standard for aluminum applications. The lightweight design simplifies handling, while the ceramic’s inert nature prevents contamination of the melt.

Foundries and aluminum recyclers use these filters to remove oxide films, slag, and non-metallic particles, resulting in cleaner castings with fewer defects. Buyers typically source them in bulk for continuous casting lines or batch processes, with packaging designed to prevent breakage during transit. The filters integrate into existing gating systems and are available in standard disc, square, or rectangular shapes to fit most pouring basins.

Univeternity Machinery Co., Ltd. is based in Tongzhou, Beijing, China, and operates as an importer of industrial ceramics. The company’s profile indicates a focus on machinery and filtration solutions for metal processing, with a listed trust tier of harbor. Its address in the Tongzhou district places it within a key industrial hub near the capital, facilitating logistics for domestic and international buyers.

The supplier’s response metrics show a current rate of 0.00, with no average response time recorded. This suggests that direct communication may require follow-up through alternate channels. The company’s role as an importer implies it sources components like ceramic foam filters from manufacturers and distributes them to end users, rather than producing the filters in-house.
