An aluminium inner-grooved tube also called an internal toothed tube, is the lightweight and cost reduction solution for air conditioning heat exchanger, representing an attractive alternative to copper tube. The inner grooves can be straight or helical. The height range of inner grooves varies from 0.05 to 0.3mm. The higher groove, the better heat transfer performance. It is widely used in heat exchangers for household and commercial air conditioning systems.
1. Compared with,Internal Toothed Tube has higher corrosion resistance and better toughness.
2. Has lower quenching sensitivity. This allows it to maintain its strength properties, stress corrosion cracking resistance and fracture toughness levels.
3. The cold workability of 7050 aluminium sheet is not good, but it can be processed.
4. Internal Toothed Tube also has good anodizing reaction.
5. Welding methods are not recommended, such as brazing, gas shielded arc welding or coated metal arc welding.
The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.
Internal Toothed Tube Uses
For the manufacture of aircraft structures and other high-stress structures with high strength and corrosion resistance, such as upper and lower wing panels, trusses and spacers. In addition, Internal Toothed Tube is also used to make high-end mobile phone casings, precision components, golf components and other products.
Union Medium Thick Aluminium Plate Uses
Internal Toothed Tube is suitable for high hardness mold, shoe mold, heavy forging, high strength parts and other fields, the products provide the original factory warranty, the global export, can be assured to purchase!
