Import Brown Fused Alumina For Refractory Raw Material — Buy in wholesale FOB from Supplier in China

Brown fused alumina for precision casting and refractory applications from Shengshi Jinyang Group Co., Ltd. is produced via electric arc furnace fusion of bauxite, with subsequent special processing to create melt film precision casting sand. The material achieves minimum 95% Al2O3 content (standard for brown fused alumina refractory grades) and is engineered for high refractoriness, low thermal expansion coefficient, and strong thermal stability. The supplier notes that specific performance parameters can be adjusted according to customer requirements, indicating customisable sizing and chemistry for jewellery casting, silica sol investment casting, and stainless steel foundry applications.

The precision casting sand variant offered here exhibits low thermal expansion, high air permeability, and easy shell removal properties that distinguish it from standard blasting grades. Typical refractory-grade brown fused alumina carries a density of 3.90 - 4.10 g/cm3 and refractoriness exceeding 1850 degrees C, though buyers should request the supplier's specific test certificates for fusion point and permanent linear change. The material substitutes for zirconia sand at approximately half the cost, with the added benefit of high recovery ratio through reclamation systems, a significant operational saving for continuous casting operations.

Primary application sectors include jewellery melt film casting, handicraft investment casting, stainless steel precision casting, watch and eyewear component manufacture, and aluminium die casting. The supplier's location in Luoyang, Henan Province places it within China's primary bauxite-alumina processing corridor. Buyers should confirm packaging specifications, available grit fractions, and whether the supplier provides technical guidance for shell system compatibility, as these details are not stated in the source material.

Shengshi Jinyang Group Co., Ltd. is headquartered at No.6 Building, Zhengda International, Houzaimen Street, Luolong District, Luoyang, Henan Province, China (postal code 471003). The company operates under the harbour trust tier within its marketplace classification. The supplier's response rate is recorded at 0.00% with zero average response hours, which indicates that direct communication channels may be underutilised or that the profile requires updated engagement metrics. Buyers should test responsiveness through the available inquiry system before relying on time-sensitive procurement schedules.

The listing positions the company as a developer of advanced brown fused alumina precision casting sand, with claims that product quality reaches the level of comparable foreign products through laboratory testing and foundry practice validation. The source description references research and development organisation and customisable performance, suggesting some in-house technical capability. However, the profile provides no verified information about production capacity, furnace count, annual output, ISO certifications, export licence status, or existing client references. Buyers should request company registration documents, quality management system certificates, and sample casting trial results to validate supplier capability independently.
