Abstract

A kind of new electrical contact material, using AgZnO2CuO materials are made, comprising following weight proportion：Ag contents 85~90%, ZnO2Content 7~14%, the additive of CuO contents 1~2%, 0.05~0.15%, additive selects at least one to be combined from Yi, mi, lithium.Above-mentioned AgZnO2CuO materials prepare the application of material as bi-metal rivet, its preparation process：Drawing-the finished product of silver ingot, copper ingot, zinc ingot metal-melting-powder by atomization-sorting-internal oxidition-shaping-hot extrusion-annealing-repeatedly-make rivet.Meet the electrical contact material that the electric switches such as various relay-contactors are used the invention provides a kind of, with preferably production and processing feature and preferable reprocessing characteristic, bimetallic composite rivet is particularly adapted to, while also overcoming the weakness of its resistance fusion welding difference.

Description

A kind of new electrical contact material
Technical field
The present invention relates to relay contacts element, particularly with regard to a kind of new electrical contact material and preparation technology.
Background technology
Contact material is the contact element of electric switch, instrument and meter etc., mainly undertakes the effect of on-off circuit and load current.Its performance quality directly affects the performance and quality of device for switching.
The Agcdo for using at present（AgCdO）Though electric contact has fabulous performance and relatively low production cost, manufacturing process is also very mature and stable, and cadmium and cadmium salt are harmful, and to environmentally undesirable.
Silver-tin oxide or indium oxide is another contact material, although there is the history of more than 20 years, but because it contains precious metal indium and the poor and poor reprocessing characteristic of production and processing characteristic, thus it is mainly used on the basis of simple shape and the use environment that need not reprocess, seem helpless if bi-metal rivet for need complex deformation, and silver is poor with the wetability of tin oxide, resistance fusion welding is poor in use.
The content of the invention
It is the defect for overcoming above-mentioned material to exist as electrical contact material, the present invention takes AgZnO2CuO replaces the material as a kind of new electrical contact material.
A kind of new electrical contact material, using AgZnO2CuO materials are made, comprising following weight proportion：Ag contains
85~90%, ZnO of amount2Content 7~14%, the additive of CuO contents 1~2%, 0.05~0.15%, additive selects at least one to be combined from Yi, mi, lithium.
Above-mentioned AgZnO2CuO materials prepare the application of material as bi-metal rivet, its preparation process：Drawing-the finished product of silver ingot, copper ingot, zinc ingot metal-melting-powder by atomization-sorting-internal oxidition-shaping-hot extrusion-annealing-repeatedly-make rivet.
Meet the electrical contact material that the electric switches such as various relay-contactors are used the invention provides a kind of, with preferably production and processing feature and preferable reprocessing characteristic, bimetallic composite rivet is particularly adapted to, while also overcoming the weakness of its resistance fusion welding difference.
Specific embodiment
With reference to embodiment, the invention will be further described, but not as limitation of the present invention：
A kind of new electrical contact material, using AgZnO2CuO materials are made, comprising following weight proportion：Ag contains
88.5%, ZnO of amount2Content 10%, CuO contents 1.4%, 0.1% additive, the additive selects at least one to be combined from yittrium oxide, Yangization mi, lithia.
Above-mentioned AgZnO2CuO materials prepare the application of material as bi-metal rivet, its preparation process：Drawing-the finished product of silver ingot, copper ingot, zinc ingot metal-melting-powder by atomization-sorting-internal oxidition-shaping-hot extrusion-annealing-repeatedly-make rivet.
The invention is characterized in that the means of production of alloy powder pre-oxidation plus powder metallurgical technique improves its processing characteristics；At the same time the microcomponents such as cupric oxide, bismuth oxide, lithia are added to improve wetability.
AgZnO2CuO material properties such as following table：
The above embodiment of the present invention, is only to clearly demonstrate examples of the invention, but is not limited to protection scope of the present invention, and all equivalent technical schemes fall within scope of the invention, and scope of patent protection of the invention should be limited by every claim.
