Alumina foam filters from Dalian Shipbuilding Import Export Company are ceramic filtration media designed for the purification of molten aluminum and its alloys. The filters are composed of at least 65% aluminum oxide (Al2O3), providing a stable and inert structure capable of withstanding temperatures up to 1200°C without degradation.
These filters feature a porous, open-cell structure with pore sizes ranging from 10 to 50 PPI (pores per inch), which traps inclusions and impurities as molten metal passes through. The pure white color indicates high-purity Al2O3 content, while the standard application temperature of ≤1200°C aligns with typical aluminum casting and foundry operations. Their use improves the mechanical properties and surface finish of the final castings by removing oxides and non-metallic particles.
Primarily used in aluminum foundries and casting facilities, these filters are critical for producing high-integrity components in automotive, aerospace, and construction industries. The filters are traded as consumable ceramic products, with China being a key global supplier. Packaging and handling are optimized for bulk industrial use, with filters often supplied in preformed blocks or plates.

Before ordering, confirm the exact pore size (PPI) and Al2O3 content to match your molten aluminum filtration requirements. Request a certificate of analysis to verify the chemical composition and thermal stability of the filters, as these properties directly impact their performance in foundry operations.
Clarify packaging and handling specifications, as alumina foam filters are fragile and require protective packaging to prevent damage during transit from Dalian. Lead times may vary depending on stock availability, so confirm whether the supplier can meet your production schedule. Agree on Incoterms such as FOB Dalian and payment terms suitable for bulk industrial orders.
Inspect the filters upon delivery for cracks, deformities, or discoloration, which may indicate compromised quality. For critical applications, conduct trial filtrations to validate performance under your specific casting conditions. Ensure all shipping documentation, including material certifications and HS classifications, is complete for customs clearance and traceability.
