| Zusammenfassung: | The invention provides a method for manufacturing low-temperature sintered counterweights. Aluminum powder is selected as the base material, nickel powder is used as the sintering active material, and high-specific-gravity tungsten powder is used as the filling material. They are uniformly mixed by a mixer in a certain proportion, and then the mixture is cold-pressed and molded into a raw body, and then the raw body is made into a sintered body through a vacuum sintering heat treatment. Finally, by using a densified process of high-pressure pressing, low-temperature sintered counterweights with different densities are obtained. |
