Aluminum rolled finned tubeMade entirely from aluminum tube, with no touch thermal resistance, high strength, resistance to thermal shock and mechanical vibration, good thermal expansion properties, and a considerable expanded heat exchange surface.Finned tubeManufactured in a strip or coiled design. Copper-aluminum composite finned tubes are made by bonding copper and aluminum tubes, then rolling them to form fins. They feature tight bonding, low thermal resistance, excellent heat transfer performance, high strength, minimal activity loss, strong corrosion resistance, and resistance to deformation under long-term hot and cold conditions, as well as a long service life. The entire finning is lubricated, free of burrs and folds, easy to clean, and facilitates the removal of condensation from the exterior surface of the fins during wet cooling in heating, ventilation, and air conditioning projects. They are also less prone to dust and scaling in dry heating and other heat exchange applications. Our factory's aluminum and copper-aluminum composite finned tubes are all anodized, offering an aesthetically pleasing appearance and effectively preventing surface corrosion.
