Embodiment 1
[0031]This example discloses a brazing metal-containing powder silver solder and preparation method for brazing hard alloy, including 20% of the flux dielectric core and 80% silver-containing metal layer that accounted for the total mass of the silver brazing material. The aluminum powder is filled in the metal wrapped inside, and the mass ratio of the flux powder in the present embodiment is shown in Table 1. The particle size of the aluminum powder is 240 nm to 400 nm, and there is no agglomeration before the mixing;
[0032]The silver-containing metal layer is wrapped as a pharmaceutical core solder, which includes the following substances: AG18.0%, Cu46.0%, Sn 2.1%, and the margin is Zn.
