Description
Technical field
Invention belongs to the metal composite scientific domain, especially relates to a kind of good percentage elongation, and bonding strength is high, and resistivity is low, tensile strength height, lower-cost copper-steel-copper composite material and preparation method thereof.
Background technology
Steel is the iron-carbon of carbon content between 0.021%-2.11%.People are collectively referred to as iron and steel with itself and iron usually, and in order to guarantee its toughness and plasticity, carbon content generally is no more than 1.7%.Outside the principal element deironing of steel, the carbon, also have silicon, manganese, sulphur, phosphorus etc.Other composition is for steel performance is distinguished to some extent.Below alphabetically list important steel, they comprise following composition:
Carbon (Carbon)
Being present in all steel, is most important hardening element.Help to increase the intensity of steel, we wish that usually other steel of cutter level have the carbon more than 0.6%, also become high carbon steel.
Chromium (Chromium)
Increase wearability, hardness the most important thing is erosion resistance, has the stainless steel of thinking more than 13%.Although so cry, if maintain improperly, all steel all can get rusty
Manganese (Manganese)
Important element helps to generate texture structure, increases soundness, and intensity, and wearability.In thermal treatment and volume pressure process, make the inner deoxidation of steel, appear at most cutter and cut with in the steel, except A-2, L-6 and CPM 420V.
Molybdenum (Molybdenum)
The carboniogenesis agent prevents that steel from becoming fragile, and keeps the intensity of steel when high temperature, appears in a lot of steel, and self hardening steel (for example A-2, ATS-34) always comprises 1% or more molybdenum, and they could hardening in air like this.
Silicon (Silicon)
Help to strengthen intensity, the same with manganese, silicon is used for keeping the intensity of steel in the production process of steel.Refer to that carbon content is less than 2% iron-carbon.Different according to composition, can be divided into carbon steel and steel alloy again.Different with purposes according to performance, can be divided into again structure iron, tool steel and property steel.
Fine copper often is known as red copper, and it has good electroconductibility, thermal conductivity and solidity to corrosion.Fine copper letter+T (copper) expression, such as T1, T2, T3 etc.The content of oxygen is extremely low, is not more than 0.01% fine copper and is called oxygen free copper, with TU (copper without) expression, such as TU1, TU2 etc.
Along with the develop rapidly of technology, metallic substance is all exhibited one's skill to the full in every field with the many merits that it has.Alloy material and manufacturing technology thereof are also more and more advanced, from and promote that the purposes of alloy is more extensive.But as steel, carbon/carbon-copper composite material, existing market mainly adopts hot compound blast, and technique falls behind, and yields poorly, and finished product is low, and production cost is high, and strip width is narrow, can only be used for finding.Therefore limit greatly its development.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides a kind of good percentage elongation, bonding strength is high, and resistivity is low, tensile strength height, lower-cost copper-steel-copper composite material and preparation method thereof.
For achieving the above object, the present invention is realized by following technical solution:
A kind of copper-steel-copper composite material, its chemical component weight ratio is: copper 5～20%, steel 80～95%, its structure is that copper and steel are combined into one.
For large industrial production is convenient, the present invention also provides the preparation method of aforesaid copper-steel-copper composite material, and described preparation process is:
A, with copper and steel by surface treatment after, be rolled into high precision steel band and high-precision copper strap through cold rolling mill;
B, by after the surface cleaning, remove surface residue, degreasing;
C, with in the middle of steel band is placed on, two copper strips are placed on the both sides of steel, are rolled into high precision copper steel composite band through cold rolling mill;
Under 650-850 ℃ the temperature, the copper steel composite band was annealed 1-4 hour in D, the usefulness vacuum oven, make the structural molecule of two kinds of metallic substance composite beds fused, and then in vacuum oven, be cooled to room temperature;
E, two kinds of bands are carried out compound, band is combined into one;
F, band is carried out finish rolling;
G, with matrix material carry out smooth, the polishing, according to user's requirement band is carried out packing after the sub-cut.
