Import 55x40mm Alumina Ceramic Six Wing Ring — Buy in wholesale FOB from Supplier in China

The 55x40mm Alumina Ceramic Six Wing Ring from Zibo Win-Ceramic Material Co. Ltd is a larger-aspect-ratio variant in the six-wing tower packing series, with an outer diameter of 55mm and height of 40mm. This geometry provides greater void fraction per unit bed depth compared to lower-profile alternatives, reducing gas pressure drop in high-throughput reactors. The supplier describes the material as precision-engineered alumina ceramic with emphasis on hardness, thermal stability, and chemical resistance, though specific purity percentages are not stated for this size variant. The Zibo, Shandong manufacturing location places production within China's principal structural ceramics cluster, with access to raw material suppliers and established kiln infrastructure.

The 40mm height versus 36mm in the related size yields a lower surface area-to-volume ratio, a trade-off that engineers specify when hydraulic capacity outweighs mass transfer efficiency requirements. The six-wing internal structure maintains mechanical integrity against compressive loads from bed weight and thermal cycling. Standard material for this product category is sintered alumina, with phase composition and porosity controlled through powder grading, binder selection, and firing curve optimisation. Typical additives for high-purity alumina ceramics include trace magnesia or yttria to control grain boundary chemistry and inhibit abnormal grain growth during sintering. The resulting microstructure determines fracture toughness and resistance to thermal shock, parameters that vary significantly between suppliers despite similarpso dimensional similarity.

Primary applications include high-temperature bearings, mechanical seals, electrical insulators, and chemical process equipment where the combination of hardness and thermal stability is critical. The aerospace, automotive, and general manufacturing sectors represent typical buyer industries. The supplier indicates suitability for extreme conditions and abrasive environments, positioning this grade for severe-service applications rather than standard chemical packing. Trade terms mentioned include FOB and CIF with flexible MOQ, though exact minimum quantities are not specified in the source data. Buyers should confirm alumina purity, maximum use temperature, and thermal expansion coefficient with Zibo Win-Ceramic Material Co. Ltd to ensure compatibility with their specific thermal and mechanical loading profiles.

Zibo Win-Ceramic Material Co. Ltd maintains its registered address at No.22, Changguo Western Road, Zhangdian District, Zibo, Shandong, 255000, China. The harbour trust tier indicates basic profile verification without extended due diligence completion. Notably, the response rate stands at 0.00% with zero average response hours recorded, suggesting that platform-mediated enquiry may not be reliable for time-sensitive procurement. The supplier's geographic position in Zibo provides proximity to bauxite-derived alumina feedstock and a skilled workforce familiar with ceramic kiln operations, though these locational advantages are not unique to this specific company.

The available profile contains no information about factory floor area, number of employees, annual turnover, year of establishment, or specific production equipment such as isostatic presses or continuous kilns. No client references, project installations, or export destinations are disclosed. The source description mentions ISO and SGS certifications without certificate numbers, scopes, or validity dates. Buyers should treat these as unverified claims until supporting documentation is provided. The product range appears to include multiple alumina ceramic geometries for industrial applications, but the depth of this portfolio is unclear from the single listing examined.
