Import Al-Si Alloys — Buy in wholesale FOB from Supplier in China

Tianjin Baienwei New Material Technology Co., Ltd. produces Al-Si alloys using rapid solidification technology, a melt-spinning or atomisation approach that yields finer microstructures than conventional casting. The material base is aluminum-silicon alloy, with silicon content varying by grade. The supplier highlights applications in automotive engine components, including rotors, pistons, cylinder liners, intake valves, and valve seats, where the alloy's low density and high-temperature strength are critical. Grades such as A356.2 for high-pressure die casting and 4047 for brazing filler represent common industry specifications in this product family.

Rapid solidification typically produces hypereutectic Al-Si alloys with silicon levels above 12 percent, though the exact composition range for Baienwei's standard grades is not stated in the source. The resulting microstructure features refined primary silicon particles and modified eutectic morphology, improving wear resistance and reducing thermal expansion compared to conventionally cast counterparts. The supplier notes high strength, good formability, and low density as characteristic properties. Standard forms for such alloys include ingot, billet, or atomised powder, depending on the downstream process.

Primary buyers are automotive OEMs and tier suppliers, aerospace contractors, and industrial casting houses serving engine and transmission programmes. The alloys are specified where weight reduction, thermal stability, and casting fluidity are simultaneously required. Mercedes-Benz, Mazda, BMW, and Ford are cited as end-users of Al-Si alloy technology in engines, though Baienwei's direct supply relationship to these manufacturers is not documented. Buyers should confirm with Tianjin Baienwei the exact grade, form, dimensional tolerances, and certification status for their specific application before requesting quotation.

Tianjin Baienwei New Material Technology Co., Ltd. is located at No. 13 Baofu Road, Economic Development Zone, Baodi District, Tianjin, China. The supplier holds a harbour trust tier designation, with a response rate of 0.00 percent and zero recorded average response hours, indicating no active engagement metrics are currently available. The facility sits within Tianjin's industrial corridor, a major hub for advanced materials and metal processing in northern China.

The company positions itself as a specialist in rapid solidification technology for Al-Si alloy production, targeting automotive, motorcycle, and military industrial applications. No verified production capacity, workforce data, revenue, ISO certification status, or named direct clients appear in the source material. The reference to adoption by major automotive brands describes industry-wide use of Al-Si alloys, not confirmed supply relationships with Baienwei specifically. Buyers should independently verify the supplier's quality management certification, production scale, and any OEM approvals before relying on the material for critical component programmes.
