An improved aluminum-titanium master alloy is provided. Such alloy contains a small be effective amount of, in weight percent, any two or more elements selected from the group consisting of carbon about 0.003 up to 0.1, sulfur about 0.03 up to 2, phosphorus about 0.03 up to 2, nitrogen about 0.03 up to 2, and boron about 0.01 up to 0.4, titanium 2 to 15, and the balance aluminum. After melting, the master alloy is superheated to about 1200 DEG C.-1300 DEG C. to put the element into solution, then the alloy is cast in a workable form. The master alloy in final form is substantially free of carbides, sulfides, phosphides, nitrides, or borides greater than about 5 microns in diameter. The alloy of this invention is used to refine aluminum products that may be rolled into thin sheet, foil, or fine wire and the like. Such grain refined products are also substantially free of carbides, sulfides, phosphides, nitrides, or borides. |
