摘要（英）：

The invention discloses a cobalt-chromium-tungsten alloy material, a cobalt-chromium-tungsten alloy ball for a ball screw bearing and a preparation method of the cobalt-chromium-tungsten alloy ball, and the ball screw bearing. The cobalt-chromium-tungsten alloy material is prepared from the following components in percentage by mass: 38 to 48 percent of cobalt, 31 to 41 percent of chromium, 16 to 18 percent of tungsten, 2 to 3 percent of nickel, 2 to 8 percent of graphite and less than or equal to 1 percent of iron and unavoidable impurity elements. With cobalt, chromium, tungsten, nickel and graphite which are used as main components, the cobalt-chromium-tungsten alloy material has the characteristics of resistance to corrosion and wear, high precision, long service life and the like, and can completely meet the requirements on a use environment and the performance of the ball screw bearing in a nuclear reactor loading and unloading device transmission system.
