Tube Harmonica Shape Aluminum
Dongyingtaixiao Trade Company offers a harmonica‑shaped aluminium tube with a pleated profile that incorporates 16 evenly spaced holes. Each tube measures 3 mm in width and 34 mm in length, and the material is an aluminium alloy classified as grade 30. The design maximises surface area, which improves thermal transfer for applications such as heat exchangers, air‑conditioning units and refrigeration systems.
In the aluminium‑tube market, grade 30 alloy typically provides a tensile strength of about 310 MPa and a corrosion‑resistance rating suitable for indoor and outdoor environments. Standard dimensional tolerance for small‑profile tubes of this size is ±0.05 mm, and surface finish is usually a mill‑finish (Ra ≤ 1.6 µm) unless a specific coating is requested. The pleated shape is common for compact heat‑exchange components, offering a high heat‑transfer coefficient while keeping the overall footprint minimal.
Buyers such as HVAC manufacturers, automotive parts distributors and OEMs looking for compact heat‑exchange solutions find this product useful. Dongyingtaixiao notes that the tubes are sourced from verified manufacturers and can be supplied in bulk quantities. While flexible minimum order quantities and shipping options like FOB or CIF are mentioned, exact lead‑times, incoterms and payment terms should be clarified with the supplier before finalising any purchase.

Sourcing Tube Harmonica Shape Aluminum from Dongyingtaixiao Trade Company - China Import Guide
When ordering the harmonica‑shaped aluminium tube, first verify the exact dimensions, hole count and alloy grade against your engineering drawings. Request a material test certificate that confirms the grade 30 composition and tensile strength, and ask the supplier to provide a tolerance report for the 3 mm × 34 mm size.
Clarify logistics early: ask the supplier to specify the expected lead‑time, the incoterm they will use (FOB, CIF or another) and the payment methods they accept, such as a letter of credit or telegraphic transfer. Understanding these details helps you plan shipping schedules and avoid unexpected costs when importing from China.
Arrange quality control measures by scheduling a pre‑shipment inspection or requesting a third‑party test report covering dimensions, surface finish and corrosion resistance. Ensure that the supplier can provide the necessary documentation, such as a mill test report and packaging list, to satisfy customs clearance and your own quality standards.
