"Air conditioner copper aluminum connecting tube"One end or both ends of the pipe are connected to a copper pipe, forming the ctructure of the copper-aluminum(-copper) joint,which are used for the tranmission of refrigerant in the refrigaration system.
The thinner copper pipe is inserted into the thiker aluminum pipe, by resistance welding with any weld flux produce a copper - aluminum joint pope.
