Description
Technical field
The invention belongs to and have conduction, anti-electric-arc, high strength concurrently, easily cut the alloy material of over-all properties, particularly a kind of copper-based multicomponent alloy material.
Background technology
Industrial pure copper has favorable conductive, heat conductivility, and plasticity is better, thereby is usually used in equipment such as conduction, heat conduction.But, develop rapidly along with industrial technology, shortcomings such as industrial pure copper intensity is low, softening temperature is low are restricted its application, this just requires to develop new high-strength, height and leads copper base alloy, this class copper base alloy of being developed at present mainly contains copper zirconium, copper chromium, copper cadmium, copper silver, copper-magnesium alloy, but owing to price height,, electroconductibility big to environmental influence do not reach many reasons such as requirement, these alloys do not use in not on a large scale and promote.
Kuttern is a kind of novel copper-base alloy that occurs in recent years, the adding of tellurium, given properties such as copper base alloy anti-electric-arc, anti-galvanic corrosion, but the add-on of tellurium and add other different elements arc resistance, tensile strength and the plasticity of kuttern is had different influences.Application number be 02113262.3 Chinese patent application disclose a kind of high-strength, height is led, the tellurium copper alloy material of high arc extinguishing, the composition of this kind alloy material is: tellurium 0.2～1.5%, rare elements 0.2～0.4%, copper 98.6～99.3%, though electric conductivity can reach 108%IACS, hard attitude tensile strength can reach 520Mpa, discharge inception voltage can reach 18KV (gap is 21.5mm), voltage breakdown can reach 25KV (gap is 21.5mm), but its tensile strength still can not satisfy the needs of engineering Application Areas fully.Application number is that 02133772.1 Chinese patent application discloses a kind of copper alloy material for contact net wire, not only contains tellurium in this Albatra metal-material, also contains lithium and magnesium, the adding of magnesium, the intensity of kuttern is increased, but electric conductivity is on the low side, only up to 76%IACS.
Summary of the invention
The present invention is directed to the deficiency that prior art exists, a kind of novel anti-electric-arc copper-based alloy material is provided, and this kind alloy material not only has good electroconductibility and anti-electric-arc characteristic, and intensity further improves, in addition, can also adjust its cutting ability according to the needs of processing.
Technical scheme of the present invention: introduce the 3rd constituent element---strengthening element chromium and other constituent elements utilize the ageing strengthening of chromium to realize high-strength highly-conductive, utilize the gas that produces in other constituent elements removal fusion process to reduce casting flaw and improve cutting ability.
Copper-tellurium-chromium multicomponent alloy material provided by the invention contains the interpolation element of copper, tellurium, chromium and adjustment performance, and the weight percent of copper, tellurium, chromium and interpolation element is as follows:
Tellurium 0.2～1.0%

Add element 0.001～0.2%
Copper surplus
Above-mentioned interpolation element is at least a kind of in lithium, rare earth, the phosphorus.
The technology of preparation copper-tellurium-chromium multicomponent alloy material is common process, its processing step comprises that batching, alloy melting, cast, cold and hot working become section bar, starting material both can adopt high purity copper, high purity tellurium, high-purity chromium as required, also can adopt industrial pure copper, technical pure tellurium, technical pure chromium.
The present invention has following beneficial effect:
1, electric conductivity height, intensity height, anti-electric-arc performance are good
● electric conductivity is 80～98%IACS, is that 02133772.1 the disclosed copper tellurium of Chinese patent application magnesium alloy is high by 10～15% than application number, and maximum is higher by 3% than Kufil (Cu-0.3Ag);
● tensile strength, soft attitude is 300～400Mpa, hard attitude is 520～620Mpa, soft attitude tensile strength and hard attitude tensile strength are that 02113262.3 the disclosed tellurium copper alloy material of Chinese patent application increases substantially than application number all, when hard attitude tensile strength was 600Mpa, electric conductivity still can reach 80～90%IACS;
● anti-electric-arc performance, discharge inception voltage are 18～21KV (gap is 21.5mm), and voltage breakdown is 22～25KV (gap is 21.5mm), all is better than Kufil (Cu-0.3Ag).
2, be convenient to adjust cutting ability
Tellurium, phosphorus all can improve the cutting ability of alloy material, therefore can pass through the add-on of add-on, the especially phosphorus of tellurium, phosphorus and adjust cutting ability.
3, oxygen, sulphur content are extremely low, than the low order of magnitude of national standard.
4, have good oxidation-resistance more than 500 ℃, and can improve the corrosion resistance of copper in the NaCl saturated solution, both all are better than industrial pure copper.
5, electroconductibility, intensity, arc resistance and cutting ability can be adjusted to according to actual requirement of engineering and distribute moulding process when, and are easy to adjust.
6, change with prescription, its grain-size can be regulated, and can improve the solidified structure of foundry goods, improves its thermal diffusivity.
7, starting material are easy to get, and adopt conventional melting equipment and conventional complete processing, and preparation technology is simple, easy handling.
8, raw materials cost changes according to performance requriements and composition proportion, and optimum value is lower by 10～20% than Kufil (Cu-0.3Ag), thereby has high cost performance, remarkable in economical benefits.
Alloy material of the present invention can replace existing Kufil, for example breaks, opens performance to improve under its high-voltage as the contact alloy; Be used as electrification railway contact net lead and accessory thereof to improve the antitorque commentaries on classics of material under the high-speed friction, finally cut down the consumption of energy, improve reliability; As free-cutting copper alloy improving Drawing abillity, thereby be prepared into small-sized copper alloy element with special purpose etc.
