Abstract

The utility model relates to a complete-clad copper and aluminum composite metal board with a large cross section. The maximum width of the copper and aluminum composite metal board is 300-400mm, and the thickness of the copper and aluminum composite metal board is 30-40mm. The copper and aluminum composite metal board consists of an inner core aluminum layer and a copper covering layer composited on the surface; and the thickness of the copper covering layer is 1-4mm. The complete-clad copper and aluminum composite metal board with the large cross section provided by the utility model integrates the advantages of high conduction property, light weight and low cost of aluminum, high chemical stability and lower contact resistance of copper and the like. The complete-clad copper and aluminum composite metal board with the large cross section is a novel conductor material and a novel decorative material, and can be widely applied to the war industry, an electronic component and the building industry.

Description

The full copper-clad aluminum clad metal sheet in a kind of heavy in section

Technical field

The utility model relates to bimetallic plates composite manufacturing field, specifically be the full copper-clad aluminum clad metal sheet in a kind of heavy in section and manufacturing process thereof.

Background technology

Copper and aluminium are important non-ferrous metals, are widely used in industry, military affairs, the field such as civilian.Copper has good conduction, heat conduction, corrosion-resistant, biocidal property and ornamental; Aluminium has good conduction, heat conductivility.Copper and aluminium are compared, and bauxite resource is abundant, the copper shortage of resources, and aluminium to have proportion little, the advantages such as low price.In application facet, simple copper plate/strip exists cost high, the shortcomings such as Heavy Weight, and simple aluminium sheet band then exists perishable, and fungistatic effect is poor, and mechanical strength is low, the problems such as poor toughness.

At present, the double metallic composite material of selling on the market only has tubing and bar, does not have heavy in section full copper-clad aluminum composite plate; Application number has been 2011102780860 patent disclosure a kind of copper aluminium composite bar of half bag; Application number is that 2011204090653 utility model patent discloses a kind of copper-aluminum composite board, but this product arranges by glass fiber mesh between copper-aluminum composite board; Full copper-clad aluminum composite plate Breadth Maximum of the present utility model can reach 300～400mm, and thickness reaches 30～40mm.And adopt metallurgical binding between the copper aluminium composite bed.

The utility model content

The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and provides a kind of heavy in section full copper-clad aluminum clad metal sheet, is conduction, heat conduction, and decay resistance is good, and surface quality is good, and is lightweight, and low copper, the aluminum composite metal plate of cost.

The utility model is the deficiency that solves the problems of the technologies described above, the technical scheme that adopts is: the full copper-clad aluminum clad metal sheet in a kind of heavy in section, the Breadth Maximum of described copper aluminum composite metal plate is 300～400mm, thickness is 30～40mm, copper aluminum composite metal plate by the inner core aluminium lamination and be compound in the surface copper capping layer form, the thickness of described copper capping layer is 1～4mm.

Beneficial effect

The full copper-clad aluminum clad metal sheet in the heavy in section that the utility model provides has been concentrated the high chemical stability of the high conduction performance of aluminium, lightweight, low cost and copper, the lower advantages such as contact resistance, be a kind of novel conductor material and ornament materials, can be widely used in military project, electronic devices and components and building trade.

Description of drawings

Fig. 1 is side-looking structural representation of the present utility model.

Mark among the figure: 1, inner core aluminium lamination, 2, copper capping layer.

The specific embodiment

As shown in the figure: the full copper-clad aluminum clad metal sheet in a kind of heavy in section, the Breadth Maximum of described copper aluminum composite metal plate is 300～400mm, thickness is 30～40mm, copper aluminum composite metal plate by inner core aluminium lamination 1 and be compound in the surface copper capping layer 2 form, the thickness of described copper capping layer 2 is 1～4mm.The full copper-clad aluminum clad metal sheet in the heavy in section that the utility model provides has been concentrated the high chemical stability of the high conduction performance of aluminium, lightweight, low cost and copper, and the lower advantages such as contact resistance are a kind of novel conductor material and ornament materials.The heavy in section that the utility model provides full copper-clad aluminum clad metal sheet utilization is consolidated-the solid phase composite principle, makes through the anaerobic rolling mill practice.Metal sheet surface is superior in quality, and is lightweight, and the bond strength of copper and aluminium is high, has kept the original surface quality of copper coin, and cost is low, low price.The full copper-clad aluminum clad metal sheet in the heavy in section that the utility model provides can be widely used in military project, electronic devices and components and building trade.

Claims

1. full copper-clad aluminum clad metal sheet in heavy in section, it is characterized in that: the Breadth Maximum of described copper aluminum composite metal plate is 300～400mm, thickness is 30～40mm, copper aluminum composite metal plate by inner core aluminium lamination (1) and be compound in the surface copper capping layer (2) form, the thickness of described copper capping layer (2) is 1～4mm.
