Abstract
The specific high conductivity alloy material is a kind of unique material with conductivity over 100 % IACS, certain arc distinguishing and anticorrosive capacity, soft temperature higher than that of Ag-Cu alloy and medium or high strength. It consists of Te 0.1-0.3 wt%, Ce 0.01-0.03 wt%, and Cu 99.67-99.89 wt%. The specific high conductivity alloy material may be used in microelectronics as well as aeronautics, astronautics, weapon, etc. Especially, it may be used to replace Ag-Cu alloy and Mg-Cu alloy with conductivity incapable of meeting the requirement of high speed railway.
Description
Technical field
The present invention relates to Cu alloy material, be applicable to particularly microelectronic of Aeronautics and Astronautics, weapons, electric power, electrical equipment, electronics, emphasis has solved specific conductivity, thermal conductivity, intensity, the softening temperature of contact netting twine, particularly a kind of extraordinary high conductivity alloy material.
Background technology
Current high and new technology field, the multi-functional composite material of the most urgent expectation of state-of-the-art technology, the high conductivity be badly in need of most of Aeronautics and Astronautics, weapons, electric power, electrical equipment, electronics, microelectronics and have higher intensity particularly, it is high that thermal conductivity is also wanted, the alloy material that softening temperature is good again.As the contact netting twine of electric railway, subway, magnetic suspension train, just require high specific conductivity that higher intensity is arranged again.This is a present difficult problem of being badly in need of solution in the world.
Summary of the invention
The objective of the invention is to solve traditional has high specific conductivity with regard to intensity difference; High-strength just can not have that height is led, the contradiction of arc extinguishing, simultaneously the extraordinary high conductivity alloy material that also also just reduces with regard to variation, softening temperature of high-strength plasticity.
Technical scheme of the present invention is to realize like this.
A kind of extraordinary high conductivity alloy material is characterized in that material composition is constructed as follows:
Te：0.1％～0.3％；Ce：0.01％～0.03％；Cu：99.89％～99.67％
Described processing condition and technical process are by refining master alloy earlier, refining alloy material again.Its technical process is as follows: Ce carries out analysis of components, calculating, and Cu and Te carry out analysis of components separately, calculate, are smelted into TeCu, carry out analysis of components and calculating again, and melting Ce, TeCu become ingot casting, carry out analysis of components, finished product processing, the qualified warehouse-in of inspection after construction.
The technology of the present invention effect; Specific conductivity＞100%IACS
The present invention after testing with microexamination and Analysis on Mechanism, Te form with compound in Cu is dissolved in the copper master alloy, being chain is arranged in parallel along crystal boundary and intracrystalline distribution, the adding of Ce has the mechanical property that improves material little to the specific conductivity influence, forms high melting compound with impurity lead, bismuth in the material and is tiny ball distribution of particles and improves high-temp plastic in the intragranular crystal grain thinning.Extraordinary high conductivity material is a kind of material with a series of unique functions.Its specific conductivity surpasses 100%IACS, and certain arc extinguishing and resistance to corrosion are arranged.Softening temperature is higher than yellow gold.It is strong to high-strength intensity in prescription, extraordinary melting, processing can reach.
The objective of the invention is to solve traditional has high specific conductivity with regard to intensity difference; High-strength just can not have that height is led, the contradiction of arc extinguishing, simultaneously the extraordinary high conductivity alloy material that also also just reduces with regard to variation, softening temperature of high-strength plasticity.The present invention makes high conductivity, high heat conductance, high strength and ideal softening temperature realize organic unity.It is imperative that its replaces yellow gold, non-it do not belong to.Current electric railway train will raise speed, and not having high performance material of the present invention is impossible realize.Therefore target of the present invention is exactly to solve the serious problems that do not reach requirement because of railway speed increase specific conductivity, softening temperature.Adopting this kind material to make the contact netting twine estimates to make the train speed-raising to reach more than the 300km/h.
