Abstract
The invention discloses an aluminum alloy plate for a vehicle, which is the aluminum alloy plate of the Al-Zn-Mg series and comprises the following ingredients according to mass percent: 4.0% to 5.0% of Zn, 1.2% to 2.5% of Mg; 0.5% to 1.0% of Cu; not higher than 1.0% of Si; 0.1% to 0.3% of of Mn; not higher than 0.3% of Fe, and the balance of Al and inevitable trace elements. Through the manner, the aluminum alloy plate for the vehicle can improve the strength, corrosion resistance, tensile property and the like of the aluminum alloy plate, has outstanding stress, corrosion and fracture resistance under a high-corrosivity environment and a tensile condition, and is suitable for being made into the outer plate of a motor vehicle.
Description
Technical field
The present invention relates to metal material field, particularly relate to a kind of automobile-used aluminium alloy plate.
Background technology
The energy, environmental protection, safety are the three large problems that world today's automotive industry faces.Alleviate automotive dead weight, can reduce energy consumption, environmental contamination reduction, the fuel economy of raising automobile is saved limited resources.Body of a motor car accounts for 30% of automobile gross weight, replaces conventional steel plates can make the car load loss of weight about 47% with aluminium alloy on the automobile inner and outer plates, the every reduction of automotive dead weight 100kg, and oil consumption can reduce by 0.4～1.0 L/km.When bearing same impact, aluminium sheet can many impact-absorbing than steel plate can 50%.Therefore, aluminium alloy becomes the preferred material of automotive light weight technology, becomes the focus that each large automaker pays close attention to.
At present, be mainly the A1-Mg-Si aluminium alloy for the manufacture of the material of auto body sheet, but this class material is difficult to take into account intensity and plasticity in the course of processing, and when the content of Mg and Si alloying element is too much, can affects the tensile property of aluminium alloy.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide a kind of automobile-used aluminium alloy plate, can improve intensity, corrosion resistance nature and the tensile property etc. of aluminium alloy plate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of automobile-used aluminium alloy plate is provided, it is a kind of Al-Zn-Mg line aluminium alloy plate, comprise the following ingredients that forms by mass percentage: Zn:4.0%-5.0%, Mg:1.2%-2.5%, Cu:0.5%-1.0%, Si :≤1.0%, Mn:0.1%-0.3%, Fe :≤0.3%, all the other are Al and inevitably micro-.
In a preferred embodiment of the present invention, described inevitable microalloy element comprises Ti, Sr and Zr.
In a preferred embodiment of the present invention, the mass percent of described Ti is 0.1%-0.2%.
In a preferred embodiment of the present invention, the mass percent of described Sr is 0.1%-0.2%.
In a preferred embodiment of the present invention, the mass percent of described Zr is 0.1%-0.2%.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of automobile-used aluminium alloy plate, reasonably optimizing coupling by the alloy element, improve intensity, corrosion resistance nature and the tensile property etc. of aluminium alloy plate, make it in highly corrosive environments He under the stretching condition, have good stress corrosion resistant fracture property, be applicable to maker motor-car outside plate.
Embodiment
The below is described in detail preferred embodiment of the present invention, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
The embodiment of the invention comprises:
A kind of automobile-used aluminium alloy plate, it is a kind of Al-Zn-Mg line aluminium alloy plate, comprise the following ingredients that forms by mass percentage: Zn:4.0%-5.0%, Mg:1.2%-2.5%, Cu:0.5%-1.0%, Si :≤1.0%, Mn:0.1%-0.3%, Fe :≤0.3%, all the other are Al and inevitably micro-.
Wherein, described inevitable microalloy element comprises Ti, Sr and Zr.
The mass percent of described Ti is 0.1%-0.2%.Its principal feature is that density is little, and physical strength is large, easily processing, and have good corrosion resistance, be not subjected to the impact of atmosphere and seawater.At normal temperatures, can not corroded by dilute hydrochloric acid, dilute sulphuric acid, nitric acid or dilute alkaline soln.Because Ti is tough and tensile, acid resistance is good, be widely used in the multiple alloy.
The mass percent of described Sr is 0.1%-0.2%.Its principal feature is that softness has ductility.
The mass percent of described Zr is 0.1%-0.2%.His principal feature be corrosion-resistant, be difficult for getting rusty.
Automobile-used aluminium alloy plate of the present invention, its yield strength reaches 250Mpa, and tensile strength reaches 750Mpa, and unit elongation reaches about 30%, has good ageing resistance stability, plasticity and flange ductility.
The present invention has disclosed a kind of automobile-used aluminium alloy plate, reasonably optimizing coupling by the alloy element, improve intensity, corrosion resistance nature and the tensile property etc. of aluminium alloy plate, make it in highly corrosive environments He under the stretching condition, have good stress corrosion resistant fracture property, be applicable to maker motor-car outside plate.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
