Dongyingtaixiao Trade Company supplies a harmonica-shaped aluminum tube made from aluminium-manganese alloy 3003. The extruded profile measures 7 mm in width and 91 mm in length, with two longitudinal holes that enhance coolant flow. The tube is intended for automotive radiator and cooling-system assemblies and complies with common automotive metal standards. Its compact accordion design offers a balance of rigidity and flexibility for OEM radiator modules.
Alloy 3003 provides a typical tensile strength of 90 - 110 MPa and a corrosion-resistance class suitable for coolant exposure. In the automotive sector this alloy is favoured for its good thermal conductivity and lightweight characteristics, allowing efficient heat dissipation without adding mass. The tube’s wall thickness of about 0.4 mm is standard for radiator channels, delivering sufficient structural integrity while maintaining low pressure drop. Manufacturers often finish the surface with a milled or anodised coating to protect against corrosion.
The product is purchased by OEM part manufacturers, aftermarket radiator builders and large-scale importers who require consistent dimensions for batch production. It is shipped in wooden crates containing 100 units each, with packaging designed for protection during sea freight. Because the supplier lists no fixed MOQ or lead-time, buyers should confirm the minimum order quantity, expected delivery schedule and preferred Incoterms directly with Dongyingtaixiao Trade Company before placing an order.

Before confirming a purchase, verify the aluminium grade, dimensional tolerances and wall‑thickness specifications against the supplier’s technical data sheet. Request a recent material test report to ensure the alloy meets the 3003 composition and that corrosion‑resistance properties are documented. It is also prudent to ask for photographs of a sample tube and for confirmation of the packaging method to avoid damage during transit.
Logistics for aluminium radiator tubes typically involve sea freight in sealed wooden crates, with the supplier able to arrange loading at major Chinese ports such as Qingdao or Tianjin. Incoterms are not specified in the listing, so negotiate terms such as FOB or CIF that match your supply chain preferences. Payment methods commonly include T/T in advance or LC at sight; confirm the accepted method and any required bank documentation with Dongyingtaixiao Trade Company.
Upon arrival, conduct a visual inspection for surface defects, verify the number of holes and overall dimensions using calibrated gauges, and compare the sample against the agreed specifications. Independent third‑party inspection agencies can perform non‑destructive testing for wall thickness uniformity and tensile strength if higher assurance is needed. Retain the material test report and inspection certificate as part of your import documentation for customs clearance and future quality audits.
