Description
Technical field
The present invention relates to one kind is high-elastic in the widely used novel high-strength of high-end flexible member and electronic devices and components field
CuNiSn alloy material and preparation method thereof, belongs to non-ferrous metals processing field.
Background technology
High strength and high flexibility copper alloy is one of critical material of flexible member and electronic devices and components, and it is widely used in electronics electricity
The fields such as work, communication and navigation, auto industry and ocean engineering, mainly for the preparation of electrically conductive elastic components and parts, such as machine instrumentation, mould
Tool, temperature controller, relay, auto-parts etc..
On domestic market, Copper-Nickel-Aluminium Alloy is based on the materials such as beryllium-bronze and tin-phosphor bronze.Beryllium-bronze is a kind of excellent
Matter elastomeric material, has high intensity, hardness, wear-resisting, nonmagnetic, electrical and thermal conductivity is good and impacts the excellent properties such as no-spark.But
It is that beryllium-bronze also has the shortcomings that it is intrinsic：The oxide of beryllium or dust etc. are poisonous；Alloy property is very sensitive to being heat-treated；High temperature resists
Stress relaxation ability, should not work for a long time at relatively high temperatures；Production technology is relative complex, relatively costly, and limiting it should
With.Tin-phosphor bronze belongs to most widely used Copper-Nickel-Aluminium Alloy, but its elastic performance is relatively low, and fatigue performance is poor, only applies
In low and middle-end flexible member.CuNiSn alloy is that a kind of new high strength and high flexibility developed by AT＆T Labs of the U.S. is resistance to tired
The Copper-Nickel-Aluminium Alloy of labor function admirable, is used widely in high-end flexible member and electronic devices and components field.Normal domestic use
Wall socket or insert row are it is desirable to plug number of times >=5000 time, contact engaging and separating force：1.5N (min), general tin-phosphor bronze can meet will
Ask.For flow of the people than larger open air or public arena (as airport, high ferro station, bullet train, charging pile etc.), to socket
Usage frequency high it is desirable to plug number of times >=40000 time, contact engaging and separating force：1.5N(min).Tin-phosphor bronze (QSn6.5-0.1) can be expired
In contact engaging and separating force >=1.5N, plug number of times is 18500～20000 times to foot, crackle when plugging 30000 times；Cu-9.5Ni-
2.3Sn alloy can meet in contact engaging and separating force >=1.5N, and plug number of times is 30000～31000 times, occurs splitting when plugging 36000 times
Line.No matter tin-phosphor bronze or Cu-9.5Ni-2.3Sn alloy all can not meet the requirement of open air or public arena socket, because
This needs Cu-9.5Ni-2.3Sn alloy modification to be processed to carry heavy alloyed fatigue performance, to meet high frequency time high current
The use requirement of elastic components and parts.
Content of the invention
The main object of the present invention is to make up existing copper alloy elastic, the deficiency of fatigue durability performance, in Cu-9.5Ni-
On the basis of 2.3Sn alloy, add the alloying elements such as a small amount of Co, B, V, P, alloy system institutional framework is improved, carries
Heavy alloyed combination property, is desirably to obtain the polynary Cu-Ni-Sn alloy of a kind of high strength and high flexibility, excellent in fatigue characteristics.In order to reach
To above-mentioned purpose, the present invention is realized in：

Wrong extension, crystal grain thinning.But, solubility in copper for the boron is extremely low, and excessive boron is easily assembled in crystal boundary, produces processing crisp
Property.Therefore Boron contents should be 0.005～0.01%.
Vanadium：Vanadium as refractory metal element, can notable crystal grain thinning, alloy strength, resistance to tired can be increased substantially
Labor performance and decay resistance.
Phosphorus：Phosphorus is effective deoxidier of copper alloy, puies forward heavy alloyed mobility.Phosphorus can combine to form nickel with the nickel in copper
Phosphorus compound, has purified the nickel in copper, works in coordination with and carries heavy alloyed intensity and electric conductivity.But phosphorus content is no more than 0.5%, no
