Description

A kind of almag
Technical field
The present invention relates to field of aluminum alloy manufacturing, more particularly to a kind of almag.
Background technology
Aluminium alloy is most widely used a kind of non-ferrous metal structural material in industry, in Aeronautics and Astronautics, automobile, machinery Widely applied in manufacture, ship and chemical industry.The rapid development of industrial economy, to the demand day of Welded structural member Benefit increases, and the Research on Weldability enabled aluminum alloy to is also goed deep into therewith.Aluminium alloy is most widely used a kind of non-ferrous metal in industry Structural material, widely applied in Aeronautics and Astronautics, automobile, machine-building, ship aluminium alloy and chemical industry.With in recent years Come scientific and technical and industrial economy rapid development, the density of fine aluminium increasing to the demand of Welded structural member Small (ρ=2.7g/cm3), about the 1/3 of iron, fusing point is low (660 DEG C), and aluminium is face-centred cubic structure, therefore has very high plasticity (δ:32~40%, ψ:70~90%) it is, easy to process, it can be made into various section bars, sheet material.Corrosion resistance is good;But fine aluminium Intensity is very low, and annealed condition σ b values are about 8kgf/mm2, therefore should not make structural material.It is real by long-term production practices and science Testing, for people gradually to add alloying element and carry out reinforced aluminum with the methods of heat treatment, this has just obtained a series of aluminium alloy, By changing the composition of compound matter in aluminium alloy, the alloy product of different performance is can obtain, with applied to a variety of necks In the environment in domain.
The content of the invention
The invention discloses a kind of almag, to solve the deficiencies in the prior art.
To solve the above problems, the technical solution of the present invention is:
A kind of almag, composition are made up of following weight percentage:Silicon 0.20~0.25%, iron 0.5~0.8%, copper 0.05~0.12%, magnesium 3.0~3.5%, zinc 0.05~0.15%, chromium 0.15~0.45%, manganese 0.05~0.1%, Qi Tahan Summation≤1% is measured, surplus is aluminium.
The beneficial effects of the invention are as follows:The almag of the present invention has that corrosion resistance is good, excellent weldability, cold-workability compared with It is good, and there is moderate strength.
Embodiment
The embodiment of the present invention is described in further detail below.
The al alloy component of the present invention is made up of following weight percentage:Silicon 0.20~0.25%, iron 0.5~0.8%, copper 0.05~0.12%, magnesium 3.0~3.5%, zinc 0.05~0.15%, chromium 0.15~0.45%, manganese 0.05~0.1%, Qi Tahan Summation≤1% is measured, surplus is aluminium.
In actual applications, such a almag corrosion resistance is good, and excellent weldability, cold-workability is preferable, and with medium Intensity.The main alloy element of almag is magnesium, has good forming performance, corrosion stability, weldability, medium strong Degree, for manufacturing the sheet metal component of fuel tanker, oil pipe and vehicular traffic, ship, instrument, street lamp support and rivet, hardware system Product, electricity-device shell etc., the intensity of this alloy is high, particularly with fatigue resistance:Plasticity is high with corrosion resistance, it is impossible to heat Processing is strengthened, and in half flow harden, plasticity is fair, and plasticity is low during flow harden, and corrosion-resistant good, weldability is good, machinability Can be bad, it can polish.Purposes is mainly used in the high plasticity of requirement and good weldability, is worked in liquid or gas medium Low load part, such as fuel tank, gasoline or grease conduits, various liquid containers and other Smaller loads zero made of deep-draw Part:Wire rod is used for making rivet.Tensile strength sigma b (MPa) 196~268, offset yield strength σ a (MPa) >=75, density 2.72 Gram/cc.
Above-mentioned embodiment is the preferred embodiments of the present invention, can not be limited the invention, and others are appointed The change or other equivalent substitute modes what is made without departing from technical scheme, are included in the protection of the present invention Within the scope of.
