| description | The invention provides a method for making non-magnetic counterweight. Aluminum powder is selected as the base material and tungsten powder with high specific gravity is used as the filling material. They are uniformly mixed by a mixer according to a certain ratio, and then the mixture is cold-pressed to make green embryos, which are then subjected to vacuum sintering heat treatment to make a sintered body. Finally through a high-pressure compaction process, non-magnetic counterweights of different densities are obtained. |
