The invention discloses a nonstick aluminum castable. The nonstick aluminum castable comprises the following components in mass parts: 20-25 parts of special-grade alumine with the size of 3-5 mm, 10-15 parts of special-grade alumine with the size of 1-3 mm, 5-10 parts of brown corundum with the size of 0.088-1 mm, 5-10 parts of kyanite with the size of 80 meshes, 10-15 parts of brown corundum fine powder with the size of 200 meshes, 3-5 parts of aluminum oxide micropowder, 3-5 parts of calcium aluminate cement, 2-5 parts of silicon micropowder, 7-14 parts of barium sulfate, 1-2 parts of boron nitride, 0.15-0.3 parts of sodium tripolyphosphate, 0.1-0.2 parts of sodium hexametaphosphate and 0.05-0.1 parts of fiber material. The nonstick aluminum castable disclosed by the invention produced by fully utilizing the superior ratio of boron nitride and barium sulfate has the advantages of better thermal shock resistance, aluminum corrosion resistance and longer service life.
