Metals are alloyed into aluminum using a solid compact comprised of particles containing a high concentration of the metal to be added. The compacts are prepared by blending finely divided particles of the metal containing material with a salt fluxing agent, then compacting the mixture into a readily useable form such as a pellet. The resultant pellet provides rapid dissolution of the alloying constituent in the aluminum whether cold charged to the furnace or added to a molten bath over a wide range of bath temperatures.
