Preparation method of molybdenum-copper alloy with high molybdenum content

The invention discloses a preparation method of the molybdenum-copper alloy with high molybdenum content. The preparation method of the high-molybdenum-content molybdenum-copper alloy comprises the following steps of molybdenum powder treatment, carrying out airflow crushing on the molybdenum powder to obtain the non-agglomerated molybdenum powder; spray granulation, adding water and a binder intothe non-agglomerated molybdenum powder, stirring to obtain uniform slurry, then preparing the uniform slurry into spherical molybdenum powder by adopting a spray granulation method; automatic pressing step, carrying out automatic compression molding on the spherical molybdenum powder to obtain a blank; glue discharging step, removing the binder in the blank to obtain a blank; copper infiltrationstep, performing copper infiltration treatment on the blank to obtain the molybdenum-copper alloy. The preparation method has the advantages of being high in efficiency, high in compactness, uniform in structure, good in consi
