Abstract
The invention discloses an aluminum alloy material with good inoxidizability. The aluminum alloy material comprises elements in percentage by weight as follows: 37.5-41.9 percent of zirconium, 10.2-11.6 percent of vanadium, 5.4-5.9 percent of molybdenum, 3.2-3.5 percent of ferrum, 6.7-7.4 percent of chromium, 32.4-33.6 percent of manganese and 0.2-0.5 percent of other few impurities. The aluminum alloy material has the effects of high corrosion resistance, high strength heat treatable alloy and good inoxidizability.
Description
Technical field
The present invention relates to a kind of aluminium alloy, be specifically related to the good aluminum alloy materials of a kind of antioxygen.
Background technology
Aluminium alloy is a most widely used class non-ferrous metal structured material in the industry, in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry, widely apply, along with the in recent years develop rapidly of science and technology and industrial economy, demand to the Welded structural part is increasing, makes the Research on Weldability of aluminium alloy also thereupon deeply.The widespread use of aluminium alloy has promoted the development of aluminum alloy solder technology, and the Application Areas of aluminium alloy has been expanded again in the simultaneously development of welding technique, so the welding technique of aluminium alloy is just becoming one of focus of research.
The density of fine aluminium is little, and (aluminium is face-centred cubic structure for ρ=2.7g/cm3), approximately be 1/3 of iron, fusing point low (660 ℃), therefore have very high plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), be easy to processing, can be made into various section bars, sheet material.Corrosion resistance is good; But the intensity of fine aluminium is very low, and as-annealed condition σ b value is about 8kgf/mm2, therefore should not make the structure material.By long-term production practice and scientific experiment, people come reinforced aluminum to add the methods such as alloying element and utilization thermal treatment gradually, and this has just obtained a series of aluminium alloy.The alloy that adds certain element formation can also have higher intensity in the advantages such as maintenance fine aluminium light weight, σ b value can reach 24～60kgf/mm2 respectively.Like this so that its " specific tenacity " (ratio σ b/ ρ of intensity and proportion) surpasses a lot of steel alloys, become desirable structured material, be widely used in the aspects such as machinofacture, Transport Machinery, power machine and aircraft industry, the fuselage of aircraft, covering, pneumatic plant etc. are often with the aluminium alloy manufacturing, to alleviate deadweight.Adopt aluminium alloy to replace the welding of steel plate materials, structural weight can alleviate more than 50%.Aluminium alloy density is low, but strength ratio is higher, approaches or surpasses the high-quality steel, and plasticity is good, can be processed into various section bars, has good electroconductibility, thermal conductivity and corrosion stability, industrial being widely used, and usage quantity is only second to steel.
Summary of the invention
The object of the present invention is to provide and make that the good aluminum alloy materials of antioxygen that makes has that corrosion resistance is high, the good aluminum alloy materials of a kind of antioxygen of high strength Heat tratable alloy and good in oxidation resistance effect.
Technical scheme of the present invention is: the good aluminum alloy materials of a kind of antioxygen, comprise the elements such as zirconium, vanadium, molybdenum, iron, chromium, manganese and other a small amount of impurity, each element wt proportioning is that zirconium accounts for 37.5%-41.9%, vanadium accounts for 10.2%-11.6%, molybdenum accounts for 5.4%-5.9%, and iron accounts for 3.2%-3.5%, and chromium accounts for 6.7%-7.4%, manganese accounts for 32.4%-33.6%, and other a small amount of impurity account for 0.2%-0.5%.
In a preferred embodiment of the present invention, described aluminum alloy materials is by heat treatment process system.
In a preferred embodiment of the present invention, each composition weight proportion of aluminum alloy materials that described antioxygen is good is that zirconium accounts for 39.7%, and vanadium accounts for 10.7%, and molybdenum accounts for 5.6%, and iron accounts for 3.3%, and chromium accounts for 7.1%, and manganese accounts for 33.3%, and other a small amount of impurity account for 0.3%.
The good aluminum alloy materials of a kind of antioxygen of the present invention has that corrosion resistance is high, an effect of high strength Heat tratable alloy and good in oxidation resistance.
Embodiment
Below in conjunction with preferred embodiment of the present invention is described in detail, 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.
In one embodiment, the good aluminum alloy materials of a kind of antioxygen, comprise the elements such as zirconium, vanadium, molybdenum, iron, chromium, manganese and other a small amount of impurity, each element wt proportioning is that zirconium accounts for 37.5%-41.9%, and vanadium accounts for 10.2%-11.6%, molybdenum accounts for 5.4%-5.9%, iron accounts for 3.2%-3.5%, and chromium accounts for 6.7%-7.4%, and manganese accounts for 32.4%-33.6%, other a small amount of impurity account for 0.2%-0.5%, and described aluminum alloy materials is by heat treatment process system.
Further specify, each composition weight proportion of aluminum alloy materials that described antioxygen is good is that zirconium accounts for 39.7%, and vanadium accounts for 10.7%, and molybdenum accounts for 5.6%, and iron accounts for 3.3%, and chromium accounts for 7.1%, and manganese accounts for 33.3%, and other a small amount of impurity account for 0.3%.
Can debug according to different ratios according to different demands, thereby reach different results of use, aluminium alloy density is low, but strength ratio is higher, approaches or surpasses the high-quality steel, and plasticity is good, can be processed into various section bars, have good electroconductibility, thermal conductivity and corrosion stability, industrial being widely used, usage quantity is only second to steel.Aluminium alloy divides two large classes: cast aluminium alloy, use under as cast condition; Wrought aluminium alloy can bear press working, and mechanical property is higher than as cast condition.Can be processed into the aluminium alloy material of various forms, specification.Mainly for the manufacture of air material, daily living article, door and window for building etc.Aluminium alloy can be divided into wrought aluminium alloy and cast aluminium alloy by working method.Wrought aluminium alloy is divided into again not heat-treatable strengthened type aluminium alloy and heat-treatable strengthened type aluminium alloy.Not heat-treatable strengthened type can not improve mechanical property by thermal treatment, can only realize strengthening by cold deformation, and it mainly comprises rafifinal, industrial rafifinal, commercial-purity aluminium and corrosion-resisting aluminium etc.Heat-treatable strengthened type aluminium alloy can improve mechanical property by thermal treatment means such as quenching and timeliness, and it can be divided into duralumin, wrought aluminium, ultralumin and particular aluminum alloy etc.The invention provides the good aluminum alloy materials of a kind of antioxygen, have that corrosion resistance is high, an effect of high strength Heat tratable alloy and good in oxidation resistance.
The specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
