Abstract
The utility model relates to a layered composite solder which is used for welding between metal and metal, between metal and ceramic, between ceramic and ceramic and the like. The composite solder is composed of an upper layer (1) made of precious metal-based alloy, an intermediate layer (2) made of anaerobic copper or copper-silver alloy and a lower layer (3) made of precious metal-based alloy, wherein the layer thickness ratio of the upper layer to the middle layer to the lower layer is (0.5-2): (0.5-4): (0.5-2). The precious metal-based alloy solder of the upper layer and the precious metal-based alloy solder of the lower layer is one or two of Ag, AgCu10-50, AgCu10-50 Ni0.1-0.45, AgCu23-28 In9-16, AgCu20-32 Pd5-20, Au79-81Cu19-21, Au82-83Ni17-18, AuAg2-20Cu10-55. The interlayer layer is made of oxygen-free copper or copper-silver alloy. The composite solder has good welding performance and can meet the performance requirement of the vacuum electronic industry on the solder.
Description
Technical field
The utility model relates to technical field of welding materials, specifically a kind of stratiform composite soldering of welding between mother metals such as metal and metal, metal and pottery, pottery and pottery of being used for.
Background technology
At present, the vacuum electronic industry has the part solder to adopt money base or auri solder, carries out the welding between the materials such as copper, pottery, expansion alloy.This type of solder, because of containing noble metal, thereby price is higher and the noble metal resource-constrained; For reducing the noble metal dosage in the solder; Some solders adopt formation new alloys such as adding Cd, Zn; But can not be used for the vacuum electronic industry because of elements such as the Cd that contains high-vapor-pressure, Zn exist, some solders adopt the mode of adding Sn, Si to form alloy, but because added elements such as Sn, Si; Cause material too crisp and be difficult for being shaped to strip or silk ribbon, thus big limitations their use.
The utility model content
The purpose of the utility model is to provide that a kind of to contain noble metal amount low, has low melting point, low-steam pressure, can satisfy the vacuum electronic industry requirement, and can be shaped to the stratiform composite soldering of strip or silk ribbon shape.
The composite soldering of the utility model is that the lower floor by the intermediate layer of the upper strata of precious metal-based alloy, oxygen-free copper or Kufil and precious metal-based alloy connects and composes successively, and the bed thickness ratio of upper, middle and lower-ranking is 0.5～2:0.5～4:0.5～2.

The stratiform composite soldering of the utility model; Be that the bilevel precious metal-based alloy band that width is suitable and the oxygen-free copper stripe or the Kufil band in intermediate layer carry out surface treatment (cleaning up); In will going up then down three-layer metal be rolled after superimposed compoundly, obtain the stratiform composite soldering through diffusion annealing and precision rolling.The stratiform composite soldering of the utility model has good welding performance.Can carry out various hot and cold pressure machine-shapings, can weld and machining, can satisfy the performance requirement of vacuum electronic industry brazing material.
The beneficial effect of the utility model is:
1, the intermediate layer of stratiform composite soldering can effectively absorb the thermal stress after the welding, further prevents mother metal (metal that is soldered is called mother metal) hot tearing.
2, the throat depth fluctuation is little, helps the dimensional accuracy control of workpiece.
3, the thermal shock load that workpiece receives can be effectively carried in the intermediate layer of stratiform composite soldering, and workpiece will obtain increase to a certain degree service life.
4, scolder has been practiced thrift noble metal dosage, and cost is lower.

Fig. 1 is the stratiform composite soldering structural representation of the utility model.
Among the figure, the 1-upper strata is the precious metal-based alloy, and the 2-intermediate layer is oxygen-free copper or Kufil, and 3-lower floor is the precious metal-based alloy.
The specific embodiment
As shown in Figure 1, the stratiform composite soldering of the utility model is connected and composed by the intermediate layer 2 of upper strata 1, oxygen-free copper or the Kufil of precious metal-based alloy and the lower floor 3 of precious metal-based alloy successively; The bed thickness of upper, middle and lower-ranking is than being the arbitrary ratio in 0.5～2:0.5～4:0.5～2 scopes, for example: 1:4:1; 1:3:1; 1:2:1; 1:2.5:1; 1:0.5:1; 1:3.5:1; 1:4.5:1; 1:5:1 etc.
