Background technique
Brass is the alloy as composed by copper and zinc.It is known as if it is a variety of alloys that the element by two kinds or more forms
Special brass.Brass has stronger wear-resisting property, and brass is commonly used for manufacturing valve, water pipe, air-conditioning connection pipe for internal-external unit and dissipate
Hot device etc..For corrosion resistance, intensity, hardness and the machinability etc. for improving brass, it is added on a small quantity (generally in copper-zinc alloy
1%~2%, minority is extremely a other up to 5%~6% up to 3%~4%) tin, aluminium, manganese, iron, silicon, nickel, lead and other elements, constitute ternary, four
Member, even quinary alloy, as complex brass, also known as special brass.The type of brass alloys is more, since price is low, extensively
As electric contact materials such as connector, terminal, relay, switches.But compared with phosphor bronze, beryllium copper, Corson alloy etc., brass
The poor defect of the generally existing elastic property of alloy.
Currently, the prior art have been disclosed it is some as the conductive materials such as connector, terminal, relay, switch
Technical solution, such as publication No. are the Chinese patent application of CN 101454468A, disclose the brass containing 15-40 mass %Zn
Alloy can be added for the intensity, heat resistance, proof stress retentivity etc. for further improving alloy with total 0.01-5.0 mass %
Add one or more of Sn, Ni, Si, Fe, Mn, Co, Ti, Cr, Zr, Al and Ag.But the raw material components of the brass alloys compare
Complexity, and elastic property be not it is very excellent, there is the space that further increases.Therefore, develop a kind of formula it is simpler,
More preferably brass alloys conductive material becomes a kind of urgent need to elastic property.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a kind of formulas simply, elastic property is excellent
Brass alloys conductive material and preparation method thereof.For achieving the above object, the invention adopts the following technical scheme:

Zn 30wt%, Sn 1.5wt%, Fe 1.5wt%, Co 0.8wt%, Cr 0.8wt%, Ag 0.8wt%, surplus Cu.
A kind of preparation method of the brass alloy material of high elastic modulus of the invention, comprising the following steps:
(1) ingredient: according to the component of high elastic modulus brass alloys, match take each raw material for standby respectively；
(2) raw material Cu, raw material Zn, raw material Sn, raw material Fe, raw material Co, Cr material, raw material A g melting: are sequentially added into smelting furnace
Middle carry out melting, smelting temperature are 1180-1250 DEG C, cover the drying graphite powder of 10mm thickness, keep the temperature 20-30min；Then exist
It casts at 1120-1180 DEG C, obtains casting brass alloys having a size of 24mm × 60mm × 160mm brass alloys ingot casting
Ingot is obtained after milling face and broken end truncate having a size of 20mm × 50mm × 140mm workpiece to be added；
(3) it processes :-rolling-- pre- finish rolling-annealing-pickling-finish-rolling process preparation of annealing in annealing-according to hot rolling-roughing；Specifically
Workpiece to be added heats 100-120 minutes first in stepping furnace, and temperature is 800-850 DEG C, and then the plate of 3.5m thickness is made in hot rolling
Base；Roughing, in roll the thickness of rear slab be respectively 2.0mm, 1.1mm；The thickness of slab is respectively after pre- finish rolling and finish rolling

Count one or more of 0.01-5.0 mass % addition Sn, Ni, Si, Fe, Mn, Co, Ti, Cr, Zr, Al and Ag.But, existing skill
The addition that art teaches alloying element simultaneously may cause the reduction of conductivity, manufacturing reduces, cost of material increases etc., therefore
It must take into account this point.These elements are less than 0.01 mass %, then not performance characteristic improvement.On the other hand, on
The total amount for stating element is more than 5.0 mass %, then conductivity significantly reduces.And the present invention is ground to alloying element composition and ratio
Study carefully, pass through a large amount of screening test, it has unexpectedly been found that, the element of specific components is according to specific proportion, brass alloys obtained
With beyond the elastic property expected.Meanwhile optimal embodiment is shown, when addition element be Sn 1.5wt%, Fe 1.5wt%,
When Co 0.8wt%, Cr 0.8wt%, Ag 0.8wt%, brass alloys have optimal elastic property, while leading to brass alloys
Electric rate does not influence too much.
The present invention compared with the prior art the utility model has the advantages that brass alloys conductive material of the invention have it is very excellent
Elastic property and electric conductivity, elasticity modulus reach 119.3Gpa, and conductivity reaches 43%IACS；The present invention is that inventor passes through
What a large amount of test and creative labor obtained, pass through the base of brass alloys conductive material technical solution in the prior art
It improves on plinth, by the consumption proportion between screening element species, adjustment element, is played in terms of improving elastic property
Synergistic effect, and still there is excellent electric conductivity, the well beyond expection of those skilled in the art.

It casts at 1120-1180 DEG C, obtains casting brass alloys having a size of 24mm × 60mm × 160mm brass alloys ingot casting
Ingot is obtained after milling face and broken end truncate having a size of 20mm × 50mm × 140mm workpiece to be added；
(3) it processes :-rolling-- pre- finish rolling-annealing-pickling-finish-rolling process preparation of annealing in annealing-according to hot rolling-roughing；Specifically
Workpiece to be added heats 100-120 minutes first in stepping furnace, and temperature is 800-850 DEG C, and then the plate of 3.5m thickness is made in hot rolling
Base；Roughing, in roll the thickness of rear slab be respectively 2.0mm, 1.1mm；The thickness of slab is respectively after pre- finish rolling and finish rolling
0.6mm,0.5mm；The technological parameter annealed in preparation process are as follows: 650-750 DEG C of temperature, soaking time 1-2 hours；Pickling uses
Dilute sulfuric acid.
