The tube harmonica‑shaped aluminium component offered by Dongyingtaixiao Trade Company is fabricated from Aluminium Alloy 3003, a member of the Al‑Mn series, and measures 2 mm by 26 mm with ten evenly spaced holes along its length. The product is intended for use in vehicle radiator assemblies, heaters and intercoolers, and originates from Dongying, Shandong Province, China. The supplier highlights high‑strength, corrosion resistance and good thermal performance as key advantages of the design. The listing confirms that the profile is corrugated to maximise heat‑transfer surface area.
In automotive cooling applications, 3003 alloy typically provides a tensile strength around 130 MPa and a density of 2.73 g cm‑3, which balances lightweight construction with structural integrity. Standard thermal conductivity for this alloy is about 200 W m‑1 K‑1, supporting efficient heat dissipation. Industry practice calls for a surface finish of mill finish with a roughness Ra ≤ 3.2 µm and dimensional tolerances of ±0.05 mm to ensure proper sealing within radiator cores.
Potential buyers include OEMs, aftermarket parts distributors and system integrators that require reliable heat‑exchange tubes. The supplier can ship the tubes in bulk cartons, and while MOQ is not specified, they indicate flexibility to accommodate different order sizes. Importers should confirm the preferred Incoterm - commonly FOB Tianjin or CIF to the destination port - and verify payment and lead‑time arrangements directly with the supplier.

Before committing to purchase, ask the supplier for a mill test report confirming the alloy composition, tensile strength and corrosion‑resistance data. Verify the exact hole diameter and surface‑finish specifications to ensure compatibility with your radiator design, and request a dimensional inspection certificate for the 2 mm × 26 mm profile.
Discuss logistics early: confirm whether the shipment will be FOB from a Chinese port such as Tianjin or a CIF arrangement to your destination. Agree on lead‑time expectations based on production scheduling, and settle payment terms - typically a T/T advance with a balance against documents. Ensure that the Incoterm and freight responsibilities are clearly recorded in the contract.
Plan a pre‑shipment quality audit, either by an in‑house engineer or a third‑party inspection agency, to check dimensions, hole count and surface finish. Request the supplier’s compliance certificates, including any relevant ASTM test reports and a declaration of conformity. Proper documentation will help smooth customs clearance and maintain product reliability in the end‑use application.
