This paper presents to investigate about eutectic bonding of Al to Cu for use of Al filter dryer. The tension test was conducted by varying eutectic bonding temperature from 415℃ to 561℃ to determine optimum bonding temperature, while maintaining inserting speed of 20 ㎜/s. From the experiment, the following conclusions were obtained. The optimum eutectic bonding temperature was showed as 556℃ and then tensile strength was showed as 138 kgf. When the bonding temperature is lower than optimum bonding temperature, it falls off and bubble occurred at the bonding temperature condition increased beyond optimum bonding temperature.
