Abstract

Condenser tube is a component of the heat exchanger in automobile and air conditioning apparatus. It is generally made from the 1000 or 3000 series Al alloys that have good heat efficiency. In the case of 3000 series, these have high strength and hardness but have the disadvantage of low extruability. The development of extruding process in condenser tube with 3000 series Al alloys is studied in this paper. A study on extrusion process is performed through the 3D FE simulation in non-steady state and extrusion experimentation. Also, nano-indentation test is employed to estimate the weldability of tubes. Especially, An evaluation of the weldability using the nano-indentation is accomplished as compared with nano-hardness of welded part and the others in cross-section of tube.
