Abstract
The invention discloses an aluminum alloy profile as building material, which is an Al-Mg-Si aluminum alloy. The aluminum alloy profile comprises the following components in percentage by mass: 0.5-0.6 percent of Mg, 0.3-0.4 percent of Si, 0.01-0.05 percent of Mn, 0.01-0.05 percent of Cu, no more than 0.3 percent of Fe and the balance of Al and inevitable trace elements, wherein the ratio of Mg to Si is 1.3-1.85. In such a way, the strength, the corrosion resistance, the weather resistance and the like of the aluminum alloy profile can be improved, and thus, the aluminum alloy profile is suitable for being used as the building material.
Description
Technical field
The present invention relates to metal material field, particularly relate to a kind of material of construction aluminium alloy extrusions.
Background technology
At present, the architectural shape of use mainly is: traditional wooden form, Sheet Steel Form and plastic mould.Although the wooden form cost is low, durability is bad; Although Sheet Steel Form intensity is very large, preponderance, cost is higher; And plastic mould is not water funk, and cost is lower, and durable, but its intensity is lower, does not meet service requirements.
Along with the burning hot expansion of real estate industry, building materials industry has obtained fast development.Aluminium alloy extrusions has become the outer manifestation of going along with sb. to guard him within the walls important in the current building, has embodied the new concept of modern architecture, because aluminium alloy extrusions intensity is large, be difficult for getting rusty, compare with common iron, weight is lighter, more be conducive to the construction of construction work, be widely used.Aluminum alloy doors and windows are main bodys that building energy consumes, and as the part of buildings, it must have the working life that equates with buildings, be approximately 70 years, and the weather-resistant property of existing aluminium alloy extrusions can't satisfy the requirement of buildings.
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 material of construction aluminium alloy extrusions, can improve intensity, corrosion resistance nature and the weather-resistant property etc. of aluminium alloy extrusions.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of material of construction aluminium alloy extrusions is provided, it is a kind of Al-Mg-Si line aluminium alloy, comprise the following ingredients that forms by mass percentage: Mg:0.5%-0.6%, Si:0.3%-0.4%, Mn:0.01%-0.05%, Cu:0.01%-0.05%, Fe :≤0.3%, all the other are Al and inevitably micro-, and Mg/Si:1.3-1.85.
In a preferred embodiment of the present invention, described inevitable microalloy element comprises Ti, Cr and Zr.
In a preferred embodiment of the present invention, the mass percent of described Ti is 0.01%-0.05%.
In a preferred embodiment of the present invention, the mass percent of described Cr is 0.01%-0.06%.
In a preferred embodiment of the present invention, the mass percent of described Zr is 0.01%-0.05%.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of material of construction aluminium alloy extrusions, reasonably optimizing coupling by the alloy element, improve intensity, corrosion resistance nature and the weather-resistant property etc. of aluminium alloy extrusions, make it be easy to the application baking vanish, have splendid decoration function, be suitable as material of construction.
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 material of construction aluminium alloy extrusions, it is a kind of Al-Mg-Si line aluminium alloy, comprise the following ingredients that forms by mass percentage: Mg:0.5%-0.6%, Si:0.3%-0.4%, Mn:0.01%-0.05%, Cu:0.01%-0.05%, Fe :≤0.3%, all the other are Al and inevitably micro-, and Mg/Si:1.3-1.85.
Wherein, described inevitable microalloy element comprises Ti, Cr and Zr.
The mass percent of described Ti is 0.01%-0.05%.Its principal feature is that density is little, lightweight, physical strength is high, and processing has metalluster easily, and good resistance to corrosion is also arranged, and is 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 has good high temperature resistant, low temperature resistant, anti-strong acid, anti-highly basic, and high strength, low-density characteristics, be used for aluminium alloy, can be anti-the high temperature of two or three hundred degree, also be able to take simultaneously the tests of subzero more than 100 degree, under this low temperature, still old good toughness and embrittlement not.
The mass percent of described Cr is 0.01%-0.06%.Its principal feature is to be ductile, and all is stable to oxygen and moisture at normal temperatures, is difficult for getting rusty.As the additive of aluminium alloy, can be fast light, heat-resisting, form erosion-resisting top layer on the surface of aluminium alloy, and light is attractive in appearance.
The mass percent of described Zr is 0.01%-0.05%.His principal feature has surprising corrosion resistance and resistance to elevated temperatures, is difficult for getting rusty.Surface at aluminium alloy easily forms layer oxide film, and has gloss.
The present invention has disclosed a kind of material of construction aluminium alloy extrusions, by the reasonably optimizing coupling of alloy element, improve intensity, corrosion resistance nature and the weather-resistant property etc. of aluminium alloy extrusions, make it be easy to the application baking vanish, have splendid decoration function, be suitable as material of construction.
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.
