Import 4" Spun Aluminum Tall Cone — Buy in wholesale FOB from Supplier in China

This 4-inch tall cone is produced by metal spinning, a chipless forming process that shapes aluminum alloy discs over a rotating mandrel to create seamless, axisymmetric hollow components. Richang Qiaoshan Trade Co. Ltd., located in Beijing's Chaoyang district, specifies 3003 or 5052 series aluminum alloy, both work-hardenable grades with good formability and corrosion resistance suited to the substantial deformation characteristic of spinning. The 4-inch designation refers to base diameter or height, a detail buyers must clarify with the supplier, as conical parts are dimensioned variously by major diameter, minor diameter, height, or included angle in engineering drawings.

The 3003 series (Al-Mn alloy) offers moderate strength and excellent spinning characteristics with H14 or H24 temper typical for formed components, while 5052 (Al-Mg alloy) provides higher fatigue strength and saltwater resistance, often specified as H32 or H34 temper for marine or outdoor lighting applications. Spun aluminum cones exhibit uniform wall thickness distribution when process parameters are controlled, with typical thickness variation of ±5% from nominal in production quantities. Surface finish ranges from mill (as-spun) to brushed, polished, or anodised, though the source does not specify which treatments Richang Qiaoshan applies as standard.

Primary applications include lighting fixture reflectors, cyclone separator inlets, automotive intake trumpets, and architectural acoustic baffles where the seamless construction eliminates weld-line weakness. Buyers span industrial lighting manufacturers, HVAC equipment producers, automotive aftermarket suppliers, and architectural metalwork fabricators. The cone geometry suits batch production at moderate tooling cost, making spun aluminum economical for volumes from hundreds to tens of thousands where press tooling would be capital-intensive or where design flexibility between sizes is valued.

Richang Qiaoshan Trade Co. Ltd. is registered at 4-3-103, Xinyuanxilizhongjie, Chaoyang District, Beijing 100027, China. The supplier carries a harbor trust tier with zero recorded response rate and zero average response hours on the platform, meaning no recent inquiry engagement data is available. This absence of response metrics does not indicate business status but signals that buyers should use direct channels, telephone, or trade fair contact to establish communication reliability before committing to orders.

The company profile does not disclose founding year, manufacturing facility location, employee count, annual turnover, or client references. The Beijing address suggests trading office or headquarters function rather than certain manufacturing presence; metal spinning operations in China are concentrated in Zhejiang, Jiangsu, and Guangdong provinces, so Richang Qiaoshan may operate as a trade company with subcontracted production. Buyers should request factory audit reports, ISO 9001 certification status, and direct manufacturing location details during qualification.
