Preparation method of nickel tungsten alloy target: prepare the target and provide mixed powder of tungsten and nickel (the mass ratio is 9.95:1 to 10.05:1), the cold isostatic pressing process is adopted for the tungsten and nickel mixed powder, and the tungsten and nickel mixed powder and stainless steel hollow tube are densified and preformed for the first time to form semi dense tungsten and nickel mixed powder and stainless steel initial blank, so that the subsequent hot isostatic pressing process can better compact tungsten, nickel mixed powder and stainless steel initial blank, The nickel tungsten alloy target can be obtained by better sandblasting some surfaces of the target without affecting other parts of the target that do not need sandblasting.
