Embodiment Construction
[0022] The present invention will be further explained and described below in conjunction with specific embodiments.
[0023] According to the mass percentage shown in Table 1, according to the mass percentage shown in Table 1, the Al alloy material described in the present invention was prepared. The specific preparation process is as follows: heating the alloy raw materials of B, Mn, Zn, Ni, Ag and Al according to the above weight percentages to 680 °C for 75 min under a nitrogen protective atmosphere; adding 0.5 wt of the total weight of the alloy raw materials %BaCl 2 , stirred for 30 min; then the alloy liquid was poured into shape; the casting temperature was 650 °C; then it was kept at 420 °C for 3 h for homogenization treatment, and cooled to obtain the aluminum alloy material of the radiator fin. It is then processed into heat exchanger aluminum tubes.
