Aluminum tube is a type of non-ferrous metal tube, which refers to a metal tube like material made of pure aluminum or aluminum alloy that is extruded and processed into a hollow metal tube along its longitudinal lengthAdvantages of aluminum tubes: Firstly, welding technology advantages: the welding technology of thin-walled copper aluminum tubes suitable for industrial production, known as a world-class problem, is a key technology for replacing copper with aluminum in the connecting pipes of air conditioners.Secondly, the advantage of service life: From the perspective of the inner wall of the aluminum tube, since the refrigerant does not contain water, the inner wall of the copper aluminum connecting tube will not undergo corrosion.The third advantage is energy-saving: the lower the heat transfer efficiency of the connecting pipeline between the indoor and outdoor units of the air conditioner, the more energy-efficient it is, or in other words, the better the insulation effect, the more energy-efficient it is.The fourth is excellent bending performance, easy to install and move
