Embodiment 1
[0049] Aluminum alloy raw materials were prepared according to the composition in Table 1. The aluminum alloy raw material is smelted and cast into an ingot, and the obtained ingot is mold-cast on a 160T cold die-casting machine, so as to obtain the die-cast body of the aluminum alloy of the present invention. Among them, the melting temperature is 750°C, the injection speed is 2m / s, the mold temperature is 200°C, and the casting size is 200mm×30mm×3mm.
[0050] The surface hardness, thermal conductivity, yield strength and elongation of the prepared aluminum alloy were measured, and the results are listed in Table 2.
Embodiment 2-15
[0052] The aluminum alloy die-cast body was prepared by the same method as in Example 1, except that the aluminum alloy raw material was prepared according to the composition in Table 1.
[0053] The surface hardness, thermal conductivity, yield strength and elongation of the prepared aluminum alloy were measured, and the results are listed in Table 2.
