Abstract: The present invention provides a sealing ring and a preparation method thereof. The sealing ring, based on percent by weight, includes 80%-85% of aluminum, 10%-15% of titanium, 0.1%-1% of scrap iron, and 4%-4.9% of potassium fluoroaluminate. Moreover, the present invention provides a method for preparing sealing ring, which includes the following steps: Step A: melting the aluminum in a medium-frequency induction furnace, adding the potassium fluoroaluminate to the medium-frequency induction furnace after melting the aluminum, melting and stirring the mixture evenly; Step B: adding titanium scrap or sponge titanium, and scrap iron to the mixture successively, melting and mixing the mixture totally at 800° C. to 1200° C., standing the mixture after stirring evenly; Step C: removing scum on the surface; Step D: casting into a mold to obtain a final sealing ring.
