Embodiment 1
[0023] A novel anti-oxidation multi-element alloy solder, its preparation method is as follows: (each raw material consumption sees Table 1)
[0024] (1) Put the raw materials Cu and Ni into a vacuum melting furnace according to the ratio, and after the furnace is evacuated to 0.1 Pa, the temperature in the furnace is heated to 1200 ° C, and then cooled to room temperature to make a CuNi master alloy;
[0025] (2) Put the CuNi master alloy, Ag, Si, Ce, Y, and Nd obtained in step (1) together into a vacuum melting furnace according to the ratio, and after the vacuum degree in the furnace reaches 0.04Pa, heat the furnace to 1400°C , heat preservation for 40 minutes, after all the raw materials are completely melted in the vacuum furnace to form a molten liquid, the temperature is lowered to 800°C, the molten liquid is poured into the shaping mold, and after the temperature drops to room temperature, the shaping mold is taken out from the vacuum furnace. Obtain the ingot required...
