| description | The invention belongs to the field of brazing materials, and particularly discloses a silver-copper brazing material and a preparation method and application of the silver-copper brazing material. 1%-20% of a nano silver sheet; 10%-30% of nano silver particles; 1%-10% of alloy powder; 1%-10% of an organic carrier; the melting point of the alloy powder is lower than 250 DEG C. Silver particles and copper particles with different sizes and shapes are compounded, porosity can be mutually filled, a synergistic effect is formed between a micron material and a nano material, and therefore low-temperature sintering of the micron material at the low temperature of 150-300 DEG C is achieved, the alloy powder is added, and the heat conduction performance and the heat stability of the brazing material can be effectively improved; after the silver-copper brazing material is used for connecting metal substrates, high reliability can be achieved, and an interconnection joint has good shear strength.
