Abstract
The present invention relates to a composite material of a constant-expansion alloy, particularly to an anticorrosive composite copper material of a constant-expansion alloy. The outer layer of the present invention can be sealed with soft glass, and has high resistance to corrosion. The inner layer of the present invention is made from oxygen-free copper materials, and has favorable conductivity and the present invention is suitable for manufacturing wiring terminals on the socket connectors of a compressor. The anticorrosive composite copper material of a constant-expansion alloy has the dual functions of sealing and conduction is characterized in that the anticorrosive composite copper material of a constant-expansion alloy is formed by connecting the inner layer and the outer layer, the outer layer is made from nickel, mo, copper, manganese and iron alloy materials, and the inner layer is made from copper materials. The metal components have the proportion of 41% to 51% of nickel, 1.5% to 5.0% of mo, 1.5% to 5.0% of copper and at most 1.0 % of manganese, and the rest is iron and a small amount of impurities.
Description
Affiliated field: the present invention relates to a kind of composite of anti-corrosion controlled expansion alloy, particularly a kind of anticorrosive constant-expansion alloy with composite copper material material, its skin can carry out sealing-in with soft glass, and stronger resistance to corrosion is arranged.Internal layer is an oxygenless copper material, and extremely good electric conductivity is arranged, and is applicable to the binding post of making on the compressor connector.It has the dual-use function of sealing-in, conduction.
Background technology: along with the rise of air conditioner refrigerating industry, this field be badly in need of a kind of not only can conduct electricity but also can with the advanced composite material (ACM) of soft glass sealing-in, be used for making the binding post on the compressor of air conditioner connector.The function of this connector is that external power source and compressor inside are coupled together, and its binding post internal layer is that copper is used for conducting electricity, outer and soft glass sealing-in.The outer of present this binding post composite wood is a kind of Alfer mostly with 4J28 alloy (contain chromium 28% all the other be iron), and its fatal shortcoming is cold-formed very difficult, so has restricted the production in enormous quantities of this material.Because lumber recovery is lower, about about 30%, cause material cost to increase, import price is roughly equal to about 800 yuan every kilogram of RMB, another kind of alloy such as 4J50 (iron-nickel alloy), though processing easily, corrosion stability is relatively poor, easily getting rusty in wet environment causes sealing-in place easily to produce gas leak phenomenon, and the complete machine quality is descended.The patent No. 00108098.9 discloses a kind of high-strength low-expansion alloy, and its purposes, purpose, composition, performance all fall far short in the content of the present patent application.
Summary of the invention: the object of the present invention is to provide a kind of anticorrosive constant-expansion alloy with composite copper material, it both can guarantee and the performance of soft glass sealing-in, can realize high-power electric conductivity again, and corrosion resisting property was good, easily machine-shaping.
The object of the present invention is achieved like this, designs a kind of anticorrosive constant-expansion alloy with composite copper material, it is characterized in that: it is to be connected and composed by internal layer and skin, and skin is nickel, molybdenum, copper, manganese, ferroalloy materials, and internal layer is a copper product.
The outer layer alloys material of described anticorrosive constant-expansion alloy with composite copper material, its each metal ingredient part by weight is: nickel 41%-51%, molybdenum 1.5%-5.0%, copper 1.5%-5.0%, manganese＜1.0%, all the other are iron and small amount of impurities.
Impure in the outer layer alloys material of described anticorrosive constant-expansion alloy with composite copper material, silicon＜0.6%, sulphur＜0.02%, phosphorus＜0.02%, chromium＜0.5%.
The outer layer alloys material of described anticorrosive constant-expansion alloy with composite copper material, the optimal proportion of each metal ingredient is: nickel 44.0-48.0%, molybdenum 1.8-2.2%, copper 2.0-3.4%, manganese 0.3-0.6%, all the other are iron.
The oxygenless copper material of the copper product choice criteria YB718-70 of described internal layer.
The production technology of described anticorrosive constant-expansion alloy with composite copper material is: after each the metallic element molten alloyization with the anticorrosive constant-expansion alloy with composite copper material cladding material, through forging, being rolled into bar, cross hot piercing through punch again and make pipe earlier; Be bumped into non-oxygen copper bar after being cold rolled to the tubing of certain specification; After prick, pull out, operation such as annealing, make bar.
Advantage of the present invention is: the cladding material of described anticorrosive constant-expansion alloy with composite copper material adds the spot corrosion that molybdenum can be resisted chlorion in the briny environment, adds the MoOCL2 protective layer that can form indissoluble behind the molybdenum at alloy surface, prevents the infiltration of chlorion.Add alloy behind the copper in air during heated oxide the surface form the low oxide of copper, can stop oxygen atom further to spread to inside, reduced oxidation rate, the anti-corrosion function combination that copper is different with molybdenum, strengthened the comprehensive resistance to corrosion of outer layer alloys, and the alloy behind the adding copper also helps the compound and contacting permeation of oxygen-free copper of internal layer.
Anticorrosive constant-expansion alloy with composite copper material cladding material of the present invention is austenite structure at normal temperatures, and easily machine-shaping increases substantially lumber recovery, and this anti-anticorrosive constant-expansion alloy with composite copper material has soft magnet performance preferably.The average coefficient of linear expansion of anticorrosive constant-expansion alloy with composite copper material when 530 spend is 10.5*10
-6 every degree.
The specific embodiment: the invention will be further described below in conjunction with embodiment.
Earlier after each the metallic element molten alloyization of cladding material with anticorrosive constant-expansion alloy with composite copper material, make each component content ratio of the cladding material of anticorrosive constant-expansion alloy with composite copper material be: nickel 46%, molybdenum 1.86%, copper 2.02%, manganese 0.5%, impurity silicon＜0.6%, sulphur＜0.02%, phosphorus＜0.02%, chromium＜0.5%, all the other are iron.Through forging; Be rolled into bar, cross hot piercing through punch again and make pipe; Be bumped into the accurate YB718-70 non-oxygen copper bar that is after being cold rolled to the tubing of certain specification; After prick, pull out, operation such as annealing, make the bar of 3.2 millimeters of diameters.This material proves and can form matched seal with soft glass promptly do not have gas leak phenomenon after making element installation test, can satisfy the instructions for use of element again.
