Import 50x56mm Alumina Ceramic Six Wing Ring — Buy in wholesale FOB from Supplier in China

The 50x56mm Alumina Ceramic Six Wing Ring from Zibo Win-Ceramic Material Co. Ltd features a 50mm diameter with a taller 56mm height profile than standard packing elements, manufactured in Zibo, Shandong Province from inert alumina ceramic. The supplier describes this as high-grade material with high purity, though specific Al₂O₃ percentage, density, and mechanical strength figures are not provided in the listing. The elongated aspect ratio of this six-wing design may offer modified gas-liquid contact dynamics compared to squatter ring geometries.

Inert alumina ceramic for industrial packing typically contains minimal fluxing agents and low silica content to ensure chemical stability across acid and base environments. The six-wing configuration with its radial projections creates turbulence at lower gas velocities than smooth cylindrical packings, which can improve mass transfer coefficients in absorption and stripping columns. Standard manufacturing involves isostatic or dry pressing of calcined alumina powder followed by sintering at 1400-1700°C, with the taller 56mm profile requiring careful control of green body density to prevent deformation during firing. The listing claims resistance to thermal shock and chemical corrosion, but does not quantify these properties.

Primary applications for this ring format include high-temperature insulation in electronics manufacturing, structural support in glass furnace regenerators, and chemical process equipment where the taller profile may provide greater bed depth per layer. Aerospace and automotive sectors are mentioned by the supplier as potential users, though specific approved applications or OEM qualifications are not stated. For trade terms, FOB and CIF are referenced without port specification or pricing detail, and MOQ flexibility is claimed but not quantified. Buyers should negotiate these parameters directly with Zibo Win-Ceramic Material Co. Ltd.

Zibo Win-Ceramic Material Co. Ltd operates from No.22, Changguo Western Road, Zhangdian District, Zibo, Shandong, China, 255000. The company carries a harbor trust tier designation on the marketplace with no recorded response rate or average response time, suggesting limited platform engagement history. No information is provided about year of establishment, registered capital, number of employees, production floor area, or annual turnover. The supplier profile does not indicate export experience, primary markets, or language capabilities for international communication.

This listing focuses on the 50x56mm alumina ceramic six-wing ring as a product offering, positioning it across multiple industrial sectors including aerospace, automotive, electronics, and ceramics manufacturing. The breadth of claimed applications exceeds the specific technical detail provided. No factory audit information, quality management certification, or customer reference is visible. Buyers should conduct independent due diligence on Zibo Win-Ceramic Material Co. Ltd's manufacturing capability and request documentation of their quality control procedures before committing to volume orders.
