Abstract
The utility model discloses a copper-aluminum composite board comprising a copper board and an aluminum board which is closely pressed with the copper board. The copper-aluminum 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 is a high-quality and low-price product.
Description
Technical field
The utility model relates to a kind of copper-aluminum composite plate.
Background technology
Copper material has good electrical conductivity, thermal conductivity and ductility, and hard wear resistant, 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 slightly 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-aluminum composite plate is provided, and it 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, the cost performance height.
The technical solution of the utility model is: a kind of copper-aluminum composite plate, comprise copper coin and with the aluminium sheet of the tight pressing of described copper coin.
The preparation method of above-mentioned copper-aluminum composite plate is: the composite surface of copper coin and aluminium sheet is cleaned out the superimposed placement in back, and by the two calendering being binded after the heater heating, the composite plate thickness after the shaping can reach below 1 millimeter again.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 one side that has copper coin on the composite plate can be used for more needing to conduct electricity, heat conduction and a wear-resisting side, substitute simple copper coin and use.
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: a kind of copper-aluminum composite plate, comprise copper coin 1 and with the aluminium sheet 2 of described copper coin 1 tight pressing.
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)
1. copper-aluminum composite plate is characterized in that: comprise copper coin (1) and with the tight aluminium sheet (2) of pressing of described copper coin (1).
