Embodiment 1

[0038] The content of the components involved in this embodiment is given according to the content specified in Table 1.

[0039] Aluminum silicon alloy is made according to the following steps:

[0040] Step S10, according to the weight percentage of the elements, silicon is 7.5%-10.2%, magnesium is 0.35%-0.60%, titanium is 0.10%-0.25%, vanadium is 0.10%-0.20%, copper is 1.5%-2.5%, and the balance of aluminum is used for raw material preparation. Compare;

[0041] In this embodiment, the raw materials are pure aluminum, pure magnesium, aluminum-copper alloy, aluminum-silicon master alloy, aluminum-titanium master alloy, aluminum-boron master alloy and the like. Titanium-boron alloys or aluminum-titanium-boron intermediate alloys can be used instead of aluminum-titanium intermediate alloys and aluminum-boron intermediate alloys, and other alloys can be added on the basis of aluminum-silicon alloys such as 354 and A356 with fixed components to adjust the composition of the al...

Smelting to obtain the Al alloy liquid having the above components, obtaining parts by extrusion casting, and then conducting solution solidifying and aging.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum-silicon alloy and a production method thereof. Background technique [0002] As a traditional metal material, cast aluminum alloy has the characteristics of low specific gravity, high specific strength, easy processing, low cost and corrosion resistance, flexible and simple production parts, and easy mass production. It is widely used in aviation, aerospace, automobiles, machinery, etc. industry. With the development of modern industry, the application of squeeze casting is increasing. Although squeeze casting exerts a large pressure during the forming process, which is beneficial to the forming of the casting, but due to the short forming time, it requires higher fluidity of the material than metal casting (gravity casting). However, high-strength and tough materials generally have slightly poor fluidity, so internal defects in high-strength and complex par...
