Abstract
The utility model discloses a copper-aluminum-copper composite board comprising an aluminum board and two layers of copper boards which are respectively and closely pressed on both surfaces of the aluminum board. The copper-aluminum-copper composite board not only has the good conductivity, heat transfer performance, extensity and other characteristics of the copper board, but also has the advantages of light weight and low cost of the aluminum board, and has high cost performance.
Description
Technical field
The utility model relates to a kind of copper-Solder for Al-Cu Joint Welding composite plate.
Background technology
Copper material has good electrical conductivity, thermal conductivity and ductility, and the application scenario is very extensive, but it belongs to narrow resources, so cost is higher, makes its application receive restriction; The aluminum material aboundresources, though it is weaker than copper material on performances such as conduction, heat conduction, its density is low, in light weight, cost is low; If can the advantage on the two material be merged mutually, can be subjected to the welcome of machinery production processing manufacturing industry more in conjunction with copper and aluminum material.
Summary of the invention
The utility model purpose is: a kind of copper-Solder for Al-Cu Joint Welding composite plate is provided, and it had both had characteristics such as copper coin good electrical conductivity, thermal conductivity and ductility, also had the light weight and the low advantage of cost of aluminium sheet, the cost performance height.
The technical solution of the utility model is: a kind of copper-Solder for Al-Cu Joint Welding composite plate comprises aluminium sheet and the two-layer copper coin that closely is pressed on described aluminium sheet two sides respectively.Be that folder is established one deck aluminium sheet between the two-layer copper coin, make that whole composite surface is a copper coin, play the effect same with copper coin, aluminium sheet is clipped in the middle of the copper coin, mainly plays the effect that alleviates composite plate weight and reduce the composite plate cost.
The preparation method of above-mentioned copper-Solder for Al-Cu Joint Welding composite plate is: the composite surface of two copper coins and an aluminium sheet is cleaned out the superimposed placement in back, and by again the three being rolled bonding after the heater heating, the composite plate thickness after the shaping can reach below 1 millimeter.The faying face of the utility model copper coin, aluminium sheet is in conjunction with very tight, and the two well integrates, and except the advantage that has copper coin and aluminium sheet concurrently, its processing characteristics also has raising.In use, the surface of composite plate is the copper coin material, need can be used to conduct electricity, the occasion of heat conduction, substitutes simple copper coin and uses.
The utility model has the advantages that:
1. the utility model had both had characteristics such as copper coin good electrical conductivity, thermal conductivity and ductility, also had the advantage that quality is little and cost is low of aluminium sheet, and cost is lower than simple copper material simultaneously, is a kind of high-quality low price product.
2. the combination of the utility model copper coin and aluminium sheet is tight, good mechanical property.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the schematic cross-section of the utility model composite plate.
Wherein: 1 copper coin; 2 aluminium sheets.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of copper-Solder for Al-Cu Joint Welding composite plate comprises aluminium sheet 2 and the two-layer copper coin 1 that closely is pressed on described aluminium sheet 2 two sides respectively.
The utility model can be used to make multiple heat conduction, product that electric conductivity is good, can be directly used in to replace copper sheet and do not need to change process and technology, and reduce material cost, has very high cost performance.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
Claims (1)
