Abstract
Provided is an improved aluminum-titanium master alloy containing carbon in a small but effective content and not more than about 0.1%. After melting, the master alloy is superheated to about 1200.degree.-1250.degree. C. to put the carbon into solution, then the alloy is cast in a workable form. The master alloy in final form is substantially free of carbides 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.
