从China供应商批发进口Aluminum Bar — FOB条款

Chongqing Guosheng Aluminum Co., Ltd supplies 6061 and 6063 alloy aluminum bars in T6 temper, positioned in the Xipeng Innovation Zone of Jiulongpo District, Chongqing. The 6061 alloy contains magnesium and silicon as principal alloying elements, delivering a tensile strength of approximately 310 MPa in T6 condition, while 6063 offers slightly lower strength with superior surface finish suitability. Both alloys receive solution heat treatment and artificial aging to achieve the T6 designation, with typical bar diameters ranging from 6 mm to 500 mm depending on application requirements.

These aluminum bars serve as raw material stock for flange manufacturing, structural fabrication, and mechanical engineering where corrosion resistance and machinability matter. The 6061 variant suits pressure vessel and piping applications requiring welded joints, given its good weldability with 4043 or 5356 filler rods. The 6063 variant finds preference in architectural and decorative extrusions where anodizing quality counts. Standard mill test certificates accompany shipments, documenting chemical composition against ASTM B221 or DIN EN 573-3 requirements, with typical magnesium content of 0.8-1.2 maker percent in 6061 and 0.45-0.9 maker percent in 6063.

Industrial buyers include manufacturers of automotive components, aircraft interior structures, marine fittings, and precision machinery frames. The bars ship in standard bundle packaging, typically steel-strapped and oiled for sea freight protection. Buyers should verify temper certification, surface condition (drawn, extruded, or peeled), and straightness tolerances before confirming orders, as these vary with diameter and processing method.

Chongqing Guosheng Aluminum Co., Ltd operates from the Xipeng Innovation Zone in Jiulongpo District, Chongqing 400039, placing it within one of China's major inland manufacturing hubs with river port access via the Yangtze. The supplier holds a harbor trust tier, which represents a baseline verification status on the platform. The response rate shows 0.00 maker percent with zero average response hours, indicating no recorded inquiry responses within the measurement period. Buyers should treat contact reliability as unverified and initiate direct communication early in the sourcing process.

The listing offers aluminum bars in 6061 and 6063 alloys with T6 temper, targeting flange manufacturers, structural fabricators, and mechanical engineering firms. No production capacity figures, export license details, or third-party audit information appears in the available profile. The supplier does not state ISO certification, factory size, or specific quality management system accreditation. Buyers should request a current factory audit report, sample bar with mill certificate, and references from existing export clients before committing to volume orders.
