Description
This case is that application number is: 200410155250.9, and the applying date is: on August 26th, 2004, name is called: the dividing an application of the patent application case of " high-copper silverless contact for low voltage apparatus material and processing method thereof ".
Technical field:
The present invention is about the electric contact material and the manufacture method thereof of a kind of low voltage electrical apparatus industry and household electrical appliance industry.
Background technology:
At present, in electrical apparatus industry, use ag-based contact material to become traditional handicraft.As: series such as Ag-MeO, Ag-c, Ag-Ni.These materials in use all have effect preferably, but these materials all are matrix with silver.And the price of at present domestic and international silver is all rising steadily, and silver-colored resource is more and more in short supply.For this reason, everybody attentiveness is all at Xiang Jieyin, for silver-colored directional steering, the technology trends in this field has been catered in the exploitation of copper base low voltage electric contact material, disclosed already ZL.94102452.0 and ZL.98120087.7 have done a little technological development highly significant in this respect, but all there is alloy theory cost problem of higher, do not meet the circulation of the disclosed proportioning component of above-mentioned document alloy material more in the market.Quality of materials to its specific components proportioning can't be affirmed and deny absolutely.
Summary of the invention:
The present invention seeks to propose one group also is the low-voltage electric appliances used high copper content sliver and cadmium free slider material of specific component and proportioning, still has performances such as favorable conductive heat conductivility and anti-electrical arc erosion.Another object of the present invention is to provide a kind of alloy processing technology of uniqueness to make its alloy reach good performance and good cost performance.
The invention technical scheme is: a kind of low-voltage electric appliances used high copper content sliver free contactor materials is a base-material with copper, and its feature also includes aluminium, yttrium, zirconium, lanthanum, diamond, its composition proportion (percetage by weight) is an aluminium 0.1～2, yttrium 0.01～1.5, zirconium 0.01～2, lanthanum 0.05～1.5, diamond 0.05～2, all the other are copper and unavoidable impurities.
The technique processing method of uniqueness of the present invention is: all prepares by the element that above-mentioned alloy component proportioning is formed with powder, and repressed, sintering, extruding or forging, rolling punching gets finished product.
The adding of each element-specific is played good effect to the good electrical and thermal conductivity performance of improving slider material and needing among the present invention, and the adding of aluminium has improved the high-temperature oxidation resistance of copper, and the existence of small amounts aluminium also plays dispersion-strengthened action, reduces the diamond consumption.Zirconium can improve anti-melting welding ability after adding, and improves elevated temperature strength.Zirconia under the high temperature can improve the conductivity thermal diffusivity of contact.The adding of lanthanum, yttrium can make the material structure grain refinement, has strengthened the oxidation resistance under the high temperature of copper matrix at lanthanum, the yttrium particle of copper crystal boundary deposition.Diamond has high hardness, and it adds with the micro mist state, and good dispersion has dispersion-strengthened action to matrix.At high temperature, the reducibility gas that produces with not change process of stone is alleviated the oxidation of inner base.The reasonable adding of each element makes that alloy zoarium of the present invention has that good, the anti-electrical arc erosion of electrical and thermal conductivity, anti-melting welding, high temperature oxidation resisting, contact resistance are low, low price etc.
Processing method technology uniqueness of the present invention, after in prior powder metallurgy technology, having added extruding or/and forging, density, the hardness of its material are obviously improved, resistivity, temperature rise descend, high-temperature mechanical property has improvement greatly, make alloy of the present invention become the material of desirable alternative money base, can be widely used in the various low-voltage electrical apparatuses.
Slider material is the heart component of electric new product.Good electrical and thermal conductivity performance at first must be arranged, want anti-electrical arc erosion, reliable break-make and stability will be arranged, also low resistivity and favorable mechanical performance etc. will be arranged.Single component can not satisfy above-mentioned requirements simultaneously.Only choose different constituent elements, bring into play different constituent elements advantage separately, effect is preferably just arranged.
Further set forth the present invention below in conjunction with embodiment, wherein the percentage number average is with the percentage by weight number.
