Abstract
The invention provides a composite aluminum alloy strip, comprising three layers of aluminum alloy strip, respectively a first layer of Al-Si aluminum alloy strip, a layer of Al-Mn aluminum alloy strip and a second layer of Al-Si aluminum alloy strip from inside to outside, the three layers of aluminum alloy strip are made by hot rolling at 400-600 DEG C, and all hot rolled surfaces of the first layer of Al-Si aluminum alloy strip, layer of Al-Mn aluminum alloy strip and second layer of Al-Si aluminum alloy strip are coated with a layer of lubricating film.The composite aluminum alloy strip has the advantages of light weight, corrosion resistance and good brazing performance.
Description
Technical field
The present invention relates to a kind of Al-alloy band, belong to technical field of aluminum alloy technology.
Background technology
Aluminium alloy strips is a most widely used class non-ferrous metal structural material in industry, at Aeronautics and Astronautics, automobile, machine-building, boats and ships, building, finishing.And chemical industry is widely applied.Along with science and technology and the developing rapidly of industrial economy in recent years, increasing to the demand of Welded structural member, the Research on Weldability enabled aluminum alloy to is the most deeply.The extensively application of aluminium alloy promotes the development of aluminum alloy solder technology, and the application of aluminium alloy, therefore one of the solder technology of aluminium alloy just focus becoming research have been expanded again in the development of solder technology simultaneously.
The density of fine aluminium is little (ρ=2.7g/cm3), about the 1/3 of ferrum, fusing point low (660 DEG C), aluminum is face-centred cubic structure, therefore has the highest plasticity (δ: 32 ~ 40%, ψ: 70 ~ 90%), it is easy to processing, can be made into various section bar, sheet material, and corrosion resistance is good；But the intensity of fine aluminium is the lowest, annealed condition σ b value is about 8kgf/mm2, therefore should not make structural material.By long-term production practices and scientific experiments, people are gradually to add alloying element and to use the methods such as heat treatment to carry out reinforced aluminum, and this has just obtained a series of aluminium alloy.Adding the alloy that certain element formed and can also have higher intensity while keeping the advantage such as fine aluminium light weight, σ b value is respectively up to 24～60kgf/mm2.Its " specific strength " (intensity and the ratio σ b/ ρ of proportion) is so made to surpass a lot of steel alloy, become preferable structural material, it is widely used in the aspects such as machine-building, Transport Machinery, dynamic power machine and aircraft industry, the fuselage of aircraft, eyelid covering, compressor etc. are often with aluminium alloy manufacture, to alleviate deadweight.Using aluminium alloy to replace the welding of steel plate materials, construction weight can alleviate more than 50%.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of Al-alloy band.
The Al-alloy band of the present invention, it is made up of three layers of aluminium alloy strips, an Al-Si aluminum alloy strip sheet material layers, Al-Mn aluminum alloy strip sheet material layers and the 2nd Al-Si aluminum alloy strip sheet material layers it is respectively outside interior, three layers of described aluminium alloy strips are made by hot rolling, described hot-rolled temperature is 400-600 degree Celsius, and the hot rolling surface of a described Al-Si aluminum alloy strip sheet material layers, Al-Mn aluminum alloy strip sheet material layers and the 2nd Al-Si aluminum alloy strip sheet material layers all scribbles lubricant film layer.
Preferably,
Described hot-rolled temperature is 450-550 degree Celsius.
The Al-alloy band of the present invention, has technique effect lightweight, corrosion-resistant, that brazing property is good.
