Abstract
High specific capacitance alloy foil and its manufacture are disclosed. This invention relates to an aluminum alloy containing Cu 0.2 - 0.25, Mg 0.04 - 0.06, Zn 0.20, Mn 0.1 - 0.4, Fe 0.8 - 1.0, Si 1.0, Ti 0.2, and Al 100 by weight. It is melted, forged, homogenized at 600 deg.C, rolled at 500 deg.C into thick rolls, cold rolled and inter-annealed at 380 - 420 deg.C, finally rolled to be foils with thickness of 0.04 - 0.05 mm. The foils have ideal corrosion speeds to form uniform porous corrosive surface with specific capacitance of 370 - 430 Ufcm in specified conditions.
Description
Technical field: what the present invention relates to is a kind of alloy and production method thereof with high specific capacitance.
Background technology: in the existing technology, in order increasing than electric capacity, generally to be that raw material is carried out chemical corrosion in acid solution, to make its surface form the multi-hole type corrosion layer, enlarged surface is long-pending.Existing than capacitor board, its composition (weight percent) is Cu ← 0.20, Mg ← 0.05, Zn ← 0.10, Mn1.0-1.6, Fe ← 0.7, Si ← 0.60, Ti ← 0.15, the Al of other impurity summation ← 0.10 (individual element ← 0.05) and surplus.The ratio electric capacity of this alloy can only reach 80uFcm, and anti-corrosion, and corrosion speed is low, and production efficiency is low.
Summary of the invention:
The objective of the invention is to: a kind of Alloy Foil material that can obtain ideal corrosion surface and high specific capacitance is provided, and a kind of production method that obtains the Alloy Foil of ideal corrosion surface and high specific capacitance can be provided.
The object of the present invention is achieved like this:
A kind of high specific capacitance alloy foil, the alloy ingredient ratio of weight and number is: Cu0.2-0.25, Mg0.04-0.06, Zn0.20, Mn0.1-0.4, Fe0.8-1.0, Si1.0, Ti0.2, Al100, make the foil that its thickness is 0.04-0.05mm.
Above-mentioned high specific capacitance alloy foil, ratio of weight and number Cu0.2, the Mg0.3 of alloying constituent, Zn0.20, Mn0.3, Fe1.0, Si1.0, Ti0.3, Al100.
A kind of production method of high specific capacitance alloy foil, by the alloy ingredient ratio of weight and number be: Cu0.2-0.25, Mg0.04-0.06, Zn0.20, Mn0.1-0.4, Fe0.8-1.0, Si1.0, Ti0.2, Al100 or Cu0.2, Mg0.3, Zn0.20, Mn0.3, Fe1.0, Si1.0, Ti0.3, Al100, preparation raw material, forge, carrying out homogenizing at 600 ℃ handles, under 500 ℃, be rolled into thick volume, cold rollingly again carry out process annealing then and handle, the process annealing temperature is controlled at 380-420 ℃, finally rolls into the thick foil of 0.04-0.05mm.
The production method of above-mentioned high specific capacitance alloy foil, the soaking time that described homogenizing is handled is 8 hours.
The invention has the advantages that:
1. Zn, Mn are regarded as impurity in traditional aluminium alloy, need strict its content of control, in this product, it as necessary interpolation element, is joined in the alloy with high relatively amount, and the product that adopts processing method of the present invention to make, its corrosion speed is fast than common aluminum alloy, the corrosion back forms uniform porous corrosion surface, improves than electric capacity, and the ratio electric capacity of product of the present invention reaches 380-430uFcm.Its production method ratio is easier to realize, improves the content of Cu, Mg in valid interval, will help the raising of quality product.
2. Alloy Foil is employed in the motorcar air conditioner of being everlasting, and the structure of former scatterer is that many tubing intert into composite foil after soldering forms.Can change the tubing that damages during use.The application of porous flat pipe in the empty bar of automobile along with continuously extruded technology is produced proposed new requirement to heat transmission soldering composite foil gradually.With the flat motorcar air conditioner of making of porous by a perforated tube after processing with the composite foil brazing filler metal together.In case flat tube has a place to damage like this, then can cause integral body to scrap, and existing composite foil corrosion resistance is better than the corrosion-resistant energy of porous flat pipe material.So in use porous flat pipe damages prior to composite foil often, cause whole scrapping.This product is a kind ofly can satisfy the soldering requirement, can reduce the spoilage of porous flat pipe prior to the multiple paper tinsel of porous flat pipe corrosive soldering under working conditions again.
