从China供应商批发进口Alumina Powder — FOB条款

Gongyi City Wanfeng Abrasives Co., Ltd. produces alumina powder from industrial alumina and aluminum hydroxide using a low-temperature phase inversion process followed by advanced grinding. The result is a highly active, fine-grained powder with spherical particles, designed for use in refractory castables, plastics, and repair materials. The material’s fine granularity and dry, clean surface make it easy to bond, enhancing the high-temperature strength and erosion resistance of monolithic refractories.

The powder is derived from white corundum, melted at temperatures exceeding 2000°C, then crushed, magnetically separated to remove iron, and screened into various grain sizes. Standard grain sizes range from F4 to F220, with chemical composition varying based on particle size. The dense texture and high hardness of the powder make it ideal for ceramics, resin abrasives, grinding, polishing, sandblasting, and precision casting. Typical industry applications also include advanced refractories where resistance to thermal shock and abrasion is critical.

Manufacturers in sectors like steel, cement, and foundries rely on this alumina powder for its consistency and performance. The supplier’s process ensures the material meets international and national standards for grain size and chemical composition. Buyers should confirm specific grain size requirements, as the listing does not specify exact micrometer ranges. The product is suited for bulk export, with packaging tailored to user needs.

Gongyi City Wanfeng Abrasives Co., Ltd. is located in Zhengzhou, Henan Province, China, with its address listed as Construction Road. The company specializes in producing abrasive materials, including alumina powder, using advanced manufacturing techniques such as high-temperature melting and precision grinding. Its focus is on delivering materials that meet both international and national standards for grain size and chemical composition.

The supplier’s trust tier is classified as harbor, and while its response rate and average response hours are listed as zero, this indicates a lack of recorded engagement data rather than a performance assessment. The company does not provide details on certifications, production capacity, or client history in the available information. Buyers are encouraged to request these specifics directly for verification.
