Abstract
Disclosed is a copper-coated aluminium alloy row. The row is characterized by comprising a bar-shaped aluminium alloy core row, and a copper cladding layer covering the outer side of the aluminium alloy core row. The copper-coated aluminium alloy row integrates characteristics of copper and aluminium alloy, wherein the copper is characterized by being high in quality and good in conductive performance, and the aluminium alloy is characterized by being corrosion resistant, low in density and low in cost. Thus, a wire row is less in weight and low in cost. Compared with a pure copper row, the copper-coated aluminium alloy row saves cost by about 15% in the conditions of the same carrying capacity. The copper-coated aluminium alloy row utilizes the 8000 series aluminium alloy as the core row, so that the wire row has improved corrosion resistance, and service lifetime of the copper-coated aluminium alloy row is improved. Furthermore, since the copper band and the aluminium alloy core row are thoroughly cleaned and strictly protected, no black non-metal impurity is disposed at the edges of the copper layer and the aluminium alloy core row, so that the two kinds of metal atoms are good in key combination and good in anti-bending performance.
Description
Technical field
The utility model relates to one and is applicable to the electro-engineerings such as high and low voltage electrical equipment, switch contact, controller switching equipment, bus duct, and is widely used in the copper-clad aluminium alloy row of the super-large current electrolysis for production engineerings such as metal smelt, electrification plating, chemical industry caustic soda.
Background technology
Mostly traditional line row is to adopt simple metal copper to arrange material as line.In recent years, due to the scarcity of copper resource, the growth rate of copper demand has exceeded the speedup of supply, cause the price of copper to rise steadily, and copper the line is busy the more than 70% of cable manufacturing enterprise cost, constantly rise in situation at current copper valency, enterprise faces immense pressure, and searching raw material substitution product reduce costs and just become the effective ways that enterprise taps the latent power.Moreover because the bending resistance folding endurance of domestic copper bar is poor, the main dependence on import of high-grade copper bar, is therefore badly in need of providing the line row of a kind of resource abundance, good conductivity, alternative simple metal copper that manufacturing cost is relatively cheap.
Summary of the invention
The purpose of this utility model provides a kind of copper-clad aluminium alloy row for existing weak point in above-mentioned prior art just.
The aluminium alloy core row of bar platy structure is drawn together in copper cover aluminum alloy of the present utility model package, is wrapped in the exclusive copper product coating layer of aluminium alloy core.
Aluminium alloy core row described in the utility model is divided into 1:10 ~ 15% with the volume ratio of copper product coating layer.
What the aluminium alloy in the utility model aluminium in copper alloy line row adopted is 8000 commercially available series alloys, it be in fine aluminium, add silicon, iron, Tong, ?, the element such as magnesium, boron, rare earth is prepared from, and 8000 series alloys are ensureing under the prerequisite of electrical property, than the good corrosion resistance of fine aluminium, creep resistance is good, pliability is good, and its chemical composition and performance index meet the requirement of the ASTMB800 of ASTM " electrician uses 8000 series alloys "; Copper-clad coating adopts the smart copper of 99.97% above purity, and copper layer density is high, good conductivity; Advanced sub-arc welding explained hereafter for copper cover aluminum alloy mining, makes to realize metallurgical binding between copper-clad coating and aluminium alloy core row, and copper layer is longitudinally evenly distributed, good concentricity.Copper cover aluminum alloy row is lightweight in addition, good mechanical property is flexible, is convenient to transport and installation.
The performance of aluminium in copper alloy line row material of the present utility model is compared as follows:
The beneficial effects of the utility model are as follows:
The utility model is that corrosion resistance, creep resistance, low-density, the low cost of the high-quality excellent conductive performance of copper and aluminium alloy are combined as a whole, can alleviate line re-scheduling amount, reduce costs, compared with simple metal copper bar, under equal ampacity, cost 15% left and right that can decline.Simultaneously the utility model is owing to adopting 8000 series alloys to arrange as core, splicing thread row's corrosion resistance, the useful life of having improved copper-clad aluminium alloy row.In addition; owing to before clad welded, copper strips and aluminium alloy core row having been carried out to thorough cleaning and tight safeguard measure; the non-metallic inclusion that does not have black on copper layer and aluminium alloy core row's border, closes well two kinds of bonds between metallic atom, and its bending resistance folding endurance is very good.
