Description

A kind of high-strength aluminum alloy

Technical field

The present invention relates to technical field of alloy material, and in particular to a kind of high-strength aluminum alloy.

Background technology

Punch forming is a kind of common machining process, refer to depended on pressure machine and mould to sheet material, band, tubing and Section bar etc. applies external force, is allowed to produce plastic deformation or separates, so that the workpiece of shape and size needed for obtaining（Stamping parts）'s Processing molding method.The stamping parts application field that punch process is produced is extensive, including consumption electronic product, machinery, five Gold, means of transport etc..The metal material that punch forming is used is generally steel, copper alloy and aluminium alloy, with to material lightweight Pay attention to day by day, aluminium alloy obtained increasingly being widely applied.However, existing aluminium alloy is still deficient in terms of intensity Lack, accordingly, it is desirable to provide a kind of high-strength aluminum alloy is to meet use demand.

The content of the invention

Present invention aims at solving the above problems, there is provided a kind of high-strength aluminum alloy.

To achieve the above object, the invention provides a kind of high-strength aluminum alloy, it is made up of the following raw material：Zn8~19%、 Mg7~15%、Cu5~8%、Zr3~6%、Ti0.9~2.5%、Mn0.1~0.9%、Nb1.4~2.9%、Ni3.1~6.5%、Rb0.1~0.6%、 Ta0.1 ~ 0.7%, Cr1.3 ~ 1.8% and surplus Al.

The high-strength aluminum alloy, is made up of the following raw material：Zn10~15%、Mg10~13%、Cu6~8%、Zr4~6%、Ti1.3 ~ 2.2%, Mn0.2 ~ 0.8%, Nb1.6 ~ 2.1%, Ni3.3 ~ 6.1%, Rb0.2 ~ 0.5%, Ta0.3 ~ 0.6%, Cr1.4 ~ 1.7% and surplus Al。

The high-strength aluminum alloy, is made up of the following raw material：Zn12%、Mg11%、Cu7%、Zr5%、Ti1.8%、Mn0.6%、 Nb1.9%, Ni4.8%, Rb0.3%, Ta0.5%, Cr1.6% and surplus Al.

Beneficial effects of the present invention：This kind of high-strength aluminum alloy has an excellent mechanical property, especially with higher strong Degree, toughness, corrosion-resistant, antioxygenic property are good, and component segregation is slight, and surface quality is good.

Embodiment

The present invention takes following technical scheme to realize：This kind of high-strength aluminum alloy, is made up of the following raw material：Zn8~19%、 Mg7~15%、Cu5~8%、Zr3~6%、Ti0.9~2.5%、Mn0.1~0.9%、Nb1.4~2.9%、Ni3.1~6.5%、Rb0.1~0.6%、 Ta0.1 ~ 0.7%, Cr1.3 ~ 1.8% and surplus Al.

As the preferred scheme of the present invention, high-strength aluminum alloy is made up of the following raw material：Zn10~15%、Mg10~13%、 Cu6~8%、Zr4~6%、Ti1.3~2.2%、Mn0.2~0.8%、Nb1.6~2.1%、Ni3.3~6.1%、Rb0.2~0.5%、Ta0.3~ 0.6%th, Cr1.4 ~ 1.7% and surplus Al.

As the preferred scheme of the present invention, high-strength aluminum alloy is made up of the following raw material：Zn12%、Mg11%、Cu7%、 Zr5%, Ti1.8%, Mn0.6%, Nb1.9%, Ni4.8%, Rb0.3%, Ta0.5%, Cr1.6% and surplus Al.

This kind of high-strength aluminum alloy has excellent mechanical property, corrosion-resistant, anti-especially with higher intensity, toughness Oxidation susceptibility is good, and component segregation is slight, and surface quality is good.

Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea Technical scheme, all should be in the protection domain being defined in the patent claims.
