The harmonica‑shaped tube is a compact aluminium radiator component measuring 4 mm × 27 mm with eight precision‑drilled holes. It is fabricated from aluminium alloy 3003 (Al‑Mn series) as stated by the supplier. The tube’s wall thickness can range from 0.35 mm to 4.00 mm, and its width and height are listed as 8 mm - 99 mm and 2 mm - 10 mm respectively. These dimensions make it suitable for integration into vehicle cooling systems.
Alloy 3003 offers a typical tensile strength of 130 MPa and a typical thermal conductivity of 155 W·m⁻¹·K⁻¹, providing reliable heat transfer in radiator cores. The serpentine wave structure described by the supplier enhances coolant flow efficiency and reduces pressure drop. Corrosion resistance and formability are standard characteristics of the Al‑Mn series, which are valued in automotive applications. Compared with plain round tubes, the harmonica profile delivers a higher surface‑to‑volume ratio, a common industry practice for high‑capacity radiators.
Automobile manufacturers, OEM part distributors and aftermarket service providers commonly source this tube for new‑car assembly lines or repair kits. The supplier lists the product under the category of aluminium tube radiator assemblies and indicates bulk ordering is possible, though exact MOQ must be be confirmed directly. Buyers should verify the material certification, dimensional tolerances and agreed Incoterms before finalising a contract.

Sourcing Harmonica-shaped Tube from Dongying Taixiao Trade Company - China Import Guide
Before placing an order, verify the aluminium grade, wall‑thickness range and hole tolerance against the supplier’s data sheet. Request a material test report and a dimensional inspection certificate to confirm that the tube meets the required standards for radiator assemblies. Confirm whether the supplier can provide any surface‑treatment documentation if anodising is required.
Logistics for aluminium radiator parts from China typically involve sea freight with standard Incoterms such as FOB or CIF. Because the listing does not state lead‑time or payment terms, ask the supplier to specify expected production lead‑time, shipping schedule and preferred payment method, whether it be T/T, L/C or other. Clarify any packaging details, such as bulk bundling or protective wrapping, to avoid damage during transit.
Quality assurance should include visual inspection for surface defects, dimensional verification with calibrated gauges, and functional testing of thermal performance under simulated coolant flow. Arrange for a third‑party inspection agency if required, and request the inspection report before shipment. Ensure that the supplier provides a Certificate of Conformity and any applicable compliance documents for export from China.
