Abstract
The invention discloses a high-strength and high-toughness ADC12-MR aluminum alloy ingot comprising the following chemical components in mass ratio: 1.5-3.5% of copper, 9.6-12.0% of silicon, less than or equal to 0.3% of magnesium, less than or equal to 1.0% of zinc, less than or equal to 0.5% of ferrum, less than or equal to 0.5% of manganum, less than or equal to 0.5% of nickel, less than or equal to 0.3% of stannum, less than or equal to 0.1% of lead and the balance of aluminum. The ADC12-MR aluminum alloy ingot disclosed by the invention contains 1.5-1.9% of copper, 10.5-12.0% of silicon and less than or equal to 0.4% of ferrum; the ranges of the copper and the silicon are effectively controlled, and the content of the ferrum is reduced, so that the a strengthening phase Al2Si is sufficiently composed of Al and Si alloy elements, the mechanical performance index of the aluminum alloy ingot is improved, and the alloy has the tensile strength of over 250MPa and the elongation of over 1.5%.
Description
Technical field
The present invention relates to a kind of aluminum alloy ingot of high-strength and high ductility, related in particular to a kind of ADC12-MR aluminum alloy ingot of Al-Si-Cu system of high-strength and high ductility, belong to secondary alloy technical field.
Background technology
Secondary aluminum is by waste aluminum and scrap aluminium alloy material or containing the waste material of aluminium, refines and the aluminium alloy or the aluminum metal that obtain through refuse, and be an important sources of metallic aluminium.Secondary aluminum is mainly to occur with the form of aluminium alloy.Secondary aluminum is identical with primary aluminum performance, and available Regenerated Aluminium Ingot remelting, refining and purification are made various cast aluminium alloys and wrought aluminium alloy through adjusting chemical composition, and then be processed into aluminium casting or plastic working aluminium.
ADC12 is the Japanese aluminium alloy trade mark, claim again aluminium material No. 12, for Al-Si-Cu is associated gold, wherein alloy component and content are respectively copper (Cu) 1.5～3.5%, silicon (Si) 9.6～12.0%, magnesium (Mg)≤0.3%, zinc (Zn)≤1.0%, iron (Fe)≤0.9%, manganese (Mn)≤0.5%, nickel (Ni)≤0.5%, tin (Sn)≤0.3%, the tensile strength of this alloy is 230MPa, and elongation is 1%.In the component of the disclosed a kind of aluminum alloy ingot of CN 101921935 A, the content of iron is 0～0.8% at present.
Research discovery, impurity F e too high levels in alloy, makes the toughness of aluminum alloy ingot little, and elongation is not high.Iron has composition height also can make squeeze increase, squeeze wood surface quality variation, and anodic oxidation aberration increases, and causes the gloomy tarnish of material color, and low-alloyed plasticity and solidity to corrosion also fall in Fe in addition.
Summary of the invention
The object of this invention is to provide a kind of ADC12-MR aluminum alloy ingot of high-strength and high ductility, to solve above-mentioned ADC12-MR alloy property defect.
Present inventor finds that ADC12-MR secondary aluminium alloy is the heat-treatable strengthened alloy with medium tenacity, and Al, Cu and Si are main alloy element.The content of Cu is higher, and the tensile strength of section bar is just higher, but resistance to deformation also increases thereupon, and the plasticity of alloy declines, and processing characteristics degenerates, and solidity to corrosion degenerates.Si content increases, and the crystal grain of alloy attenuates, and metal fluidity increases, and castability improves, and the quantity of Si too much also can cause section bar fragility increase solidity to corrosion to degenerate simultaneously, within therefore the content of Si and Cu should be controlled at zone of reasonableness.In addition the Fe element in alloy also can be grabbed Si, and Fe can form Al-Fe-Si compound with Si, reduces Al
2the content of Si phase, thus impurity F e content should be reduced as much as possible, otherwise can cause alloy strength toughness variation, low-alloyed plasticity and solidity to corrosion are fallen.
