Abstract
The invention relates to an aluminum alloy for a liquid crystal display device wire harness. The aluminum alloy comprises the following components by atomic percent: 0.5 to 5.0 percent of nickel, cobalt and iron, 0.1 to 0.3 percent of indium, 0.3 to 2.0 percent of carbon, 0.3 to 2.0 percent of molybdenum and the balance of aluminum. Since the aluminum alloy contains transitional metal molybdenum and indium, the transfer process of electrons in oxygen atoms can be effectively maintained, electrochemical reaction caused by electrode potential can be reduced, and low resistivity and high strength can be maintained.
Description
Technical field
The invention belongs to metal material field, relate to a kind of aluminum alloy films, particularly relate to a kind of aluminium alloy for liquid-crystal display distribution.
Background technology
In field of liquid crystal, the demand of the liquid-crystal display of film-type has very large growth.Simultaneously along with large screen and the high-definition of liquid-crystal display, also more and more stricter to the requirement of wiring material.
Be now that the aluminum alloy materials of matrix is paid close attention to widely with aluminium, but aluminium alloy is because low-melting problem, there is temperature resistance problem, general aluminium alloy distribution aluminum alloy films surface after being subject to the heating of 300-400 DEG C there will be burr shape projection, and such projection can cause the short circuit of adjacent circuit under wiring condition.
Have technology to propose application materials with high melting point to manufacture aluminum alloy films distribution, but the general resistivity of this kind of materials with high melting point is higher, cannot be adapted to the distribution of film-type liquid-crystal display for this reason.
Now also have technology to propose to adopt the aluminum alloy materials containing carbon and manganese can significantly reduce the generation of burr projection and resistivity is lower.But the transparency electrode ITO of this kind of aluminium alloy distribution and indicating meter causes the change of joint resistance because of electrochemical reaction.
But this technical scheme still existing defects is exactly that the current potential of this aluminum alloy films is incomplete same with the ito film current potential of indicating meter.If when not using blocking layer, under energising, be no more than 12 hours, obvious resistance change will be produced.In the lab, all there is the obvious problem of resistance change in each aluminium alloy that the nickel above-mentioned technology mentioned, cobalt, iron carry out combining, and find that there is the generation of aluminum oxide at aluminum alloy films distribution with the ito film place of engaging of liquid-crystal display.
Summary of the invention
The present invention be directed to existing aluminum alloy films technical scheme and propose improvement opportunity, pass through the technical program, can effectively overcome aluminum alloy films distribution with indicating meter ito film between electrochemical reaction problem, and effectively overcome the generation of aluminum alloy films distribution burr shape projection.
The present invention is achieved by the following technical solutions:
A kind of be used for liquid-crystal display distribution aluminium alloy, its respectively composition comprise by atomic percentage conc: the nickel of 0.5-5.0at%, cobalt and iron, the indium of 0.1-0.3at%, the carbon of 0.3-2.0at%, the molybdenum of 0.3-2.0at%, surplus is aluminium.
The mass ratio of described nickel, cobalt and iron is 2: 1: 1.
The present invention's beneficial effect is compared with the existing technology:
Because in the aluminium alloy of the application, include transition metal molybdenum and indium, effectively can keep the transmittance process of electronics in Sauerstoffatom, reduce the electrochemical reaction because electropotential produces, and low-resistivity and high strength can be kept.
