Harmonica-Shaped Aluminum Tube
The Harmonica‑shaped aluminum tube is a precision‑formed component made from Aluminum Alloy 3003 (Al‑Mn alloy). It measures 4 mm in width and 27 mm in length, with eight evenly spaced holes along its profile. The tube carries the 3003 grade, which provides a balance of formability and moderate strength. It is marketed for use as a part of aluminium‑tube radiators in HVAC and cooling systems.
Alloy 3003 offers good corrosion resistance and adequate tensile strength for heat‑exchange assemblies. Its moderate strength and excellent thermal conductivity make it suitable for large‑capacity radiators where efficient heat transfer is required. The material’s aseismic characteristic helps maintain structural integrity under vibration. In the aluminium‑tube market, such dimensions and hole patterns are standard for modules that fit into multi‑pass radiator cores.
Importers typically source this tube for OEM radiator manufacturers and component distributors. The product is usually supplied in bundled packs, and the exact minimum order quantity should be confirmed with Dongyingtaixiao Trade Company. Buyers should request trade terms, Incoterms and payment conditions directly from the supplier before placing an order.

Sourcing Harmonica-Shaped Aluminum Tube from Dongyingtaixiao Trade Company - China Import Guide
Before placing an order, importers should obtain the supplier’s material certification for Aluminium Alloy 3003 and request a detailed drawing that confirms the 4 × 27 mm dimensions and the eight‑hole pattern. Verifying the tolerance limits on hole spacing and overall length will reduce the risk of incompatibility with radiator cores. It is also prudent to ask for a sample batch to assess surface finish and corrosion resistance in the intended operating environment.
Logistics details such as the preferred loading port in China, estimated lead time, and the Incoterms to be applied must be clarified with Dongyingtaixiao Trade Company prior to contract finalisation. Typical lead times for aluminium tube components range from two to four weeks, but the supplier’s schedule should be confirmed in writing. Payment terms are usually negotiated on a letter of credit basis, and buyers should ensure that the agreed terms align with their financing arrangements.
For quality assurance, importers can arrange a third‑party inspection in Dongying before shipment, focusing on dimensional accuracy, hole alignment and surface condition. Requesting an inspection certificate and a mill test report will provide evidence of compliance with the stated specifications. Upon arrival, customs authorities may require the material safety data sheet and the supplier’s declaration of conformity, so these documents should be secured in advance.
