The invention relates to the field of anti-scaling of downhole tools in oil fields, and particularly discloses an alloy anti-scaling device for anti-scaling of a downhole tubular column. Comprising an outer shell, the outer shell is a hollow cylinder and is divided into three parts, namely a left end connector, a right end connector and a middle shell body, the left end connector and the right end connector of the outer shell are respectively provided with an internal thread and an external thread in a turning mode, and the outer shell is connected into a pipeline through connection of the threads. And the middle shell part is provided with an anti-scale alloy sheet group, and the anti-scale alloy sheet group is blocked by an anti-scale alloy circular ring. And the anti-scale alloy sheet group is separated from and fixed to the left end and the right end of the shell through the anti-scale alloy circular rings. The anti-scaling alloy pieces are in a fan blade shape, and fluid flows in from the inlet, enters t
