Embodiment Construction

[0015] A fluorinated graphite reinforced aluminum-magnesium alloy material for automotive electronic packaging, the alloy material is made of the following raw materials in parts by weight: magnesium 5%, lithium 3%, copper 2%, zirconium 1%, titanium 0.5%, fluorinated graphite Sol 20%, pore forming agent 1%, absolute ethanol 0.5, and the balance is aluminum.

[0016] The fluorinated graphite sol is prepared by the following method: put dodecyltrimethylammonium bromide into absolute ethanol, stir until it is completely dissolved, put in fluorinated graphite, and ultrasonically vibrate and grind for 8 hours to obtain the product; The weight ratio of graphite fluoride, absolute ethanol and dodecyltrimethylammonium bromide is 1:5:0.1.

[0017] The pore forming agent is spherical urea.

[0018] The preparation method of the alloy material comprises the following steps:

[0019] (1) First mix aluminum, magnesium, lithium, copper, zirconium, titanium, pore-forming agent, and absolut...
