Price Copper Aluminium Connection Pipe Tube For AC

Mass Manufacturing Factory Price Copper Aluminium Connection Pipe Tube For Air Conditioners  Why use copper and aluminum instead of directly using aluminum tubes? 1, the metal ductility of aluminum is poor than copper, so the success rate of copper is easier to operate and the quality is higher than that of aluminum when the operation of the expanding horn at the end of the connecting tube is carried out. 2, the air conditioning system inside and outside the machine connection, whether it is a stop valve or copper nut are brass parts. Direct contact between brass and aluminum is prone to electrochemical corrosion in humid and high-salt environments. At the same time, the sealing principle of the interface is also dependent on the ductility of the metal to produce plastic deformation and achieve sealing. If the aluminum horn is used, it is easy to produce poor sealing due to the problem of aluminum ductility. Based on the above two reasons, the copper-alum…
