The balance of Al material,
wherein the content of Mo and Mn is not 0 percent at the same time.
In some cases, the Al material is a00 pure aluminum (technical pure aluminum); pure aluminum a00 inevitably contains Fe, and different grades have different aluminum contents.
However, the component of the present invention is not limited to A00 pure aluminum, and other aluminum materials with similar aluminum content and iron content should be equally within the scope of the present invention.

(ii) a
The content of Zn accounts for 0.07 percent of the alloy material.

Cr can refine grains and improve the strength of the alloy.
The second aspect of this section discloses the following:
the high-strength high-plasticity AlSi9MoMnMg die-casting aluminum alloy material comprises the following components in parts by weight
Si：8.0~11.0%，
Fe：0.1-0.3%，
Mo：0.4~0.8%，
Mn：0.15~0.35%，

Mg：0.2~0.6%，
Zn：0.07~0.08%，
Ti：0.10~0.25%，
Sr：0.01~0.03%，
The balance being Al.
At this time, Al is expressed as pure aluminum without considering impurities therein; it is within the scope of the present invention if impurities are incorporated into the component, but the total weight of the component (excluding impurities) after the impurities are tapped is consistent with the present invention.
In some cases, the Fe content is 0.15%.
The composition and proportion of each component in the first three aspects of the part have some more prominent effects.
The strength of the alloy is greatly improved after quenching and aging treatment by changing the content of Mg and Si, the maximum value is in a three-phase region, but when residual Si and Mg2Si exist in the alloy, the corrosion resistance is reduced along with the increase of the amount. Through research: in order to form Mg2Si strengthening phase by matching with the content of Si, the ratio of Mg to Si is 1.73:1, the alloy strength is improved by precipitating Mg2Si phase by aging treatment, but the elongation is reduced with the content of Mg higher than 0.6 percent, and the content of Mg is controlled to be 0.2 to 0.6 percent.
Fe can improve the mucosa phenomenon of die casting alloy, but needle-shaped beta Al5FeSi phase is inevitably generated to obstruct metal flow and easily generate loose pores, so that Fe is not added in the invention, but Fe is inevitably contained in A00 pure aluminum, and Fe is controlled to be less than or equal to 0.15 percent.
Mn can improve the harmful effect of Fe, can replace Fe atoms in a beta Al5FeSi phase, converts the beta Al5FeSi phase into a-Al (MnFe) Si, is beneficial to improving the alloy performance, controls the Mn content to be 0.15-0.35%, can improve the alloy strength, improves the corrosion resistance and the impact toughness, can generate a needle-shaped MnAl6 phase when the Mn content is too high, reduces the alloy plasticity and the strength, and can improve the aluminum sticking tendency of die casting.
Mo can also improve the harm of Fe more effectively than Mn, 0.1% of Fe is completely converted into a-Al (MoFe) Si phase after 0.3% of Mo element is added, and fine a-Al (MoFe) Si phase is uniformly distributed in an aluminum matrix, so that dislocation movement is prevented, the alloy strength is improved, the heat resistance is good, and the plasticity is good. If Mn and Mo are added simultaneously, the pre-eutectic and eutectic beta-Fe phases can be completely modified, the addition is better than that of single addition, the die casting is easier to demould, and the Mo content is controlled to be 0.4-0.8%.
The addition of Cr element makes Al (MnFe) Si phase disappear basically, Al (MnCrFe) Si phase is formed, edges and corners are passivated, stress concentration is reduced, and alloy strength and plasticity are improved. The content of Cr is controlled to be 0.15-0.35%, the Cr can refine grains, the corrosion resistance of the alloy is improved, and the heat resistance of the alloy is improved more importantly. The alloy is used together with Mo, and is more beneficial to improving the alloy performance.
Ti content is 0.1-0.25%, Al3Ti phase is formed, crystal grain is refined, if the addition amount is higher than 0.25%, the amount of impurities is large, and the corrosion resistance of the alloy is reduced. After 0.3% of Sr is added, the eutectic silicon is changed into a fibrous shape from a needle shape, and the body has a modification effect, so that the strength and the plasticity are improved.
Through the adjustment of elements, three elements of Mo, Mn and Cr are mainly added to change the harm of Fe, improve the strength and plasticity of the alloy and improve the process defects of die-casting mucosa.
