Description
Technical field
The present invention relates to a kind of metal and metal processing sectors, and in particular to a kind of power battery case aluminium alloy and its
Processing method.
Background technology
With petroleum resources reduction and car ownership increase environmental pollution aggravation, new-energy automobile it is excellent
Gesture is more and more obvious.Moreover, national industrial policies also support the development of new-energy automobile industry energetically.Therefore, new energy
Automobile industry has come into high-speed development period.The aluminium alloy of general manufacture new-energy automobile critical component-power battery case
For 3003 aluminium alloys.The alloy generally has preferable deep-draw, welding and intensity, but still suffers from some problems：During laser welding
It is bad easily to there is quality, such as stomata and gas leakage；When welding pool depth is excessive（Such as more than 0.3mm）, weldpool uniformity variation, easily
Splash, have a strong impact on the sealing and battery safety of housing.But with battery capacity increase and the increase of housing wall thickness, melt
Tank depth will necessarily also increase；Exist between deep-draw, welding and intensity three and influence each other, may be reduced if improving intensity deep
Punching performance.CN103409668A discloses a kind of housing of power cell Al-Mn alloys, composition to Al-Mn alloys and microcosmic
Tissue is limited, and has preferable welding performance, but the mechanical property of material is relatively low；CN101910434A discloses one kind
1 line aluminium alloy of housing of power cell, but the mechanical property of the material is too low, and use range will be extremely restricted；Patent
CN102206775A has invented a kind of aluminium alloy for power battery case, in order to improve the welding performance of material, invention
Person reduces the strength character of material.It is therefore desirable to develop a kind of electrokinetic cell for taking into account intensity, forming property, welding performance
Shell aluminium alloy and its corresponding processing method, to meet the needs of industry development.
The content of the invention
In view of this, the present invention provides a kind of power battery case aluminium alloy.
The present invention also provides a kind of processing method of above-mentioned power battery case aluminium alloy.
In order to solve the above technical problems, the present invention uses following technical scheme：
A kind of power battery case aluminium alloy, by weight percentage, by being prepared including following component：
Mn:1.1~1.8 wt.%；
Cu:0.05~0.25 wt.%；
Fe:0.1~0.3 wt.%；
Si:0.05~0.2 wt.%；
Mg:0.05~0.2 wt.%；
Zr:0.01~0.10 wt.%；
Ti:≤0.10 wt.%；
Surplus is Al and inevitable impurity.
Preferably, inevitable impurity content is no more than 0.10 wt.%, it is further preferred that inevitable impurity
Content is no more than 0.005 wt.%, and most preferably, the content of inevitable impurity is 0 wt.%.It is heretofore described to keep away
The impurity exempted from refers to the impurity as caused by production.
Further, count in mass ratio, Mg/Si=0.9 ~ 1.1.
Further, the face fraction 2% ~ 5% of coarse InterMetallic Compound, and spacing is 10 ~ 20 microns.
Further, the face fraction of disperse intermetallic is 1 ~ 3%, and spacing is 1 ~ 3 micron.
Further, the size of the coarse InterMetallic Compound is more than 1 micron, the size of the disperse intermetallic
Less than 1 micron.
Present invention additionally comprises a kind of power battery case aluminium alloy processing method, including step：
S1, the power battery case described in constituent and claim any one of 1-5 is carried out with aluminium alloy identical ingot casting
Homogenizing annealing processing；
S2, then hot rolling is carried out, obtain hot rolled plate；
S3, cold rolling is carried out to hot rolled plate, obtains cold-reduced sheet.
Further, in step S1, annealing includes step：400 ~ 440 °C are raised to 40 ~ 80 °C/h speed
Insulation 4 ~ 8 hours, then it is raised to 590 ~ 640 °C with same heating rate again and is incubated 8 ~ 10 hours.
Further, in step S2, to drop to 500 ~ 540 °C of progress hot rollings less than 100 °C/hour speed.
Further, step is also included after step S3：S4, cold-reduced sheet is incubated 1 ~ 3 hour at 350 ~ 430 °C.
The beneficial effect that the present invention is reached：
Mn is the essential element in the invention alloy, and it mainly plays solution strengthening and dispersion-strengtherning.Mn contents are higher,
It is more obvious to strengthen effect.But Mn too high levels, then due to forming the coarse InterMetallic Compound of a large amount of unmanageable distributions, and make
Obtain material processability to decline, its composition is advisable in 1.1 ~ 1.8 wt.%；
Cu is trace additives, and the intensity of material can be improved by solution strengthening effect.But otherwise its addition excessively should not be held
Easily cause the increase of weld crack tendency and increase material cost.Therefore the wt.% of Cu 0.05 ~ 0.25 are advisable；
Fe, Ti, Zr are trace additives, mainly start to control the effect of combinations grain.But its content should not be excessive, otherwise on the one hand will
A large amount of coarse InterMetallic Compounds are formed, are unfavorable for the lifting of performance；On the other hand, its content is excessive, also can not be effective again
Reduce the crystal grain of material.Therefore the wt.% of Fe 0.1 ~ 0.3 wt.%, Zr 0.01 ~ 0.10 wt.%, Ti≤0.10 is advisable；
Si can form intermetallic compound with Al, Fe, Mn element, be advantageous to intensity, forming property and welding performance, but its content
It is unsuitable too high, the forming property of material is otherwise influenceed, its content should be the wt.% of Si 0.05 ~ 0.2；Mg mainly rise solution strengthening with
And the effect of ageing strengthening, its content should be 0.05 ~ 0.2 wt.%.Mg/Si mass ratioes are 0.9 ~ 1.1 simultaneously, are advantageous to strengthen
The precipitation of phase.
Fire processing, rolling and annealing need to be carried out to above alloy.Homogenizing annealing is carried out to ingot casting with 40 ~ 80 °
C/h speed is raised to 400 ~ 440 °C and is incubated 4 ~ 8 hours, is then raised to 590 ~ 640 °C with same heating rate again and protects
Temperature 8 ~ 10 hours；Then to drop to 500 ~ 540 °C of progress hot rollings less than 100 °C/hour speed, and hot rolled plate is carried out cold
Roll；Cold-reduced sheet is incubated 1 ~ 3 hour at 350 ~ 430 °C.During fire, control heating rate and set low and high temperature degree fiery
The purpose of platform is to promote coarse InterMetallic Compound（Size is more than 1 micron）Transformation and disperse intermetallic compound
（Size is less than 1 micron）Precipitation and grow up.Burning hot processing more than, can make coarse InterMetallic Compound（Size is big
In 1 micron）Face fraction 2% ~ 5%, and spacing be 10 ~ 20 microns；Disperse intermetallic（Size is less than 1 micron）Face fraction
For 1 ~ 3%, spacing is 1 ~ 3 micron.The intermetallic compound of the distribution characteristics, it may be such that suction of the material in laser beam welding
Yield increases, i.e., under less laser power, you can reach larger fusion penetration, avoid failure welding（Such as splash）Hair
It is raw.Intensity and forming property are improved as well as the effective Orowan effects of intermetallic compound；Cold-reduced sheet 350 ~
430 °C are incubated 1 ~ 3 hour, mainly for improving the forming property of material.Simultaneously under the conditions of suitable Mg/Si（Such as this patent
0.9 ~ 1.1）, in annealing process, it will there is appropriate hardening constituent to be formed, further improve the strength of materials.Certain reinforcing
Mutually in follow-up welding process will dissolving, but in weldment cooling procedure, can still separate out and strengthening material again.
