Abstract
The invention discloses an aluminum alloy material of heat-exchanging fin and making method, which comprises the following parts: less than 0.10 percent Mg, less than 0.25 percent Si, 0.25-0.40 percent Cu, 0.25-0.45 percent Fe, 0.80-1.20 percent Mn, less than 0.10 percent Zn, less than 0.10 percent Ti and Al. The invention can improve dynamic property, which prevents flagging and resists fatigue.
Description
Technical field
The present invention relates to metallic substance, specifically a kind of aluminum alloy materials.
Background technology
In the prior art, the aluminum alloy materials that is used for heat exchanger inner fins such as automobile, engineering machinery is mainly by 3003 and imported materials and items, the originally used aluminum alloy materials trade mark is 3003, its chemical ingredients Si≤0.6%, Cu0.05-0.20%, Fe≤0.7%, Mn1.0-1.5%, Zn≤0.10%, unit are weight percentage.The mechanical property of this material, sink-resistance performance and fatigue performance all can not satisfy customer requirement.
Summary of the invention
The object of the present invention is to provide a kind of aluminum alloy materials and production method thereof of heat exchanger inner fin, to improve its mechanical property, sink-resistance performance and fatigue performance.
According to design provided by the present invention, this material composition is mainly: Mg≤0.10%, and Si≤0.25%, Cu0.25-0.40%, Fe0.25-0.45%, Mn0.80-1.20%, Zn≤0.10%, Ti≤0.10%, surplus is Al, unit is a weight percentage.
A kind of production method of aluminum alloy materials of heat exchanger inner fin, it is characterized in that: add once batching earlier, add aluminium ingot again, melt fully Deng aluminium ingot, furnace temperature adds remaining second batch in the time of 740-760 ℃, once preparing burden, in the process that feeds intake of second batch and aluminium ingot, the per-cent that total add-on of various compositions accounts for total charging capacity is Mg≤0.10%, Si≤0.25%, Cu0.25-0.40%, Fe0.25-0.45%, Mn0.80-1.20%, Zn≤0.10%, Ti≤0.10%, surplus is Al, unit is a weight percentage, refining 40-60 minute, fully stirs to remove slag and scratches in the ashes; Wherein once batching be the waste material and the scrap stock of heat exchanger inner fin aluminum alloy materials, and it is identical with the composition of second batch once to prepare burden, and the ratio of once preparing burden with second batch is 1: 9～12, and the Al content in the aluminium ingot is greater than 99.7%.
It is a kind of novel aluminum alloy material that the aluminum alloy materials of heat exchanger inner fin is called for short YB-5.It is obviously different that this material and commonly used 3003 aluminium alloys have, and tensile strength, unit elongation all are better than the former, and as the Al alloy composite core, also reach comparatively ideal effect, significantly better than 3003.
YB-5 is as heat exchanger inner fin, and its mechanical property, sink-resistance performance and fatigue performance are fabulous, are comparatively ideal novel materials.
Embodiment
The aluminum alloy materials composition of this heat exchanger inner fin is mainly: Mg≤0.10%, and Si≤0.25%, Cu0.25-0.40%, Fe0.25-0.45%, Mn0.80-1.20%, Zn≤0.10%, Ti≤0.10%, all the other are Al, unit is a weight percentage.
A kind of production method of aluminum alloy materials of heat exchanger inner fin, it is characterized in that: add once batching earlier, add aluminium ingot again, melt fully Deng aluminium ingot, furnace temperature adds remaining second batch in the time of 740-760 ℃, once preparing burden, in the process that feeds intake of second batch and aluminium ingot, the per-cent that total add-on of various compositions accounts for total charging capacity is Mg≤0.10%, Si≤0.25%, Cu0.25-0.40%, Fe0.25-0.45%, Mn0.80-1.20%, Zn≤0.10%, Ti≤0.10%, surplus is Al, unit is a weight percentage, refining 40-60 minute, fully stirs to remove slag and scratches in the ashes; Once batching be the waste material and the scrap stock of heat exchanger inner fin aluminum alloy materials, and it is identical with the composition of second batch once to prepare burden, and the ratio of once preparing burden with second batch is 1: 9～12, and the Al content in the aluminium ingot is greater than 99.7%.
In fusion process, behind a certain amount of waste material of adding and the scrap stock, the add-on that can save second batch to reduce cost, provides the over-all properties of this material simultaneously earlier.
Wherein, copper is main alloying element, and certain solutionizing effect is arranged.CuAl
2Tangible ageing strengthening effect is arranged.
FeAl
3The effect of refinement recrystal grain is arranged, bigger to performance impact against corrosion.
Add Mn in the aluminium alloy, can improve tensile strength and unit elongation.Can improve recrystallization temperature, and remarkable refinement recrystal grain, also can reduce the deleterious effect of iron.
Magnesium is significantly to the strengthening effect of aluminium, every increase by 1% magnesium, the tensile strength 34Mpa that raises approximately.Magnesium can add separately and forms binary Al-Mg alloy, and magnesium content is stablized during in room temperature at the alloy 7% below, generally processes the aluminium alloy magnesium content below 6%, and magnesium also can together add with other alloying elements.General its add-on should be smaller or equal to 0.10%.
Zinc adds separately in the aluminium, and is limited to the raising of alloy strength under the condition of distortion, the stress corrosion crack tendency arranged simultaneously, thereby limited its application.General its add-on should be smaller or equal to 0.10%.
Titanium is an interpolation element commonly used in the aluminium alloy, and main effect is a refinement cast structure, reduces tearing tendency, improves material mechanical performance.If add together with boron, effect is more remarkable.General its add-on should be smaller or equal to 0.10%.
