Conventional Aluminum Powder Metallurgy Alloys

Atomization is the most widely used process to produce aluminum powder. Aluminum is melted, alloyed, and sprayed through a nozzle to form a stream of very fine particles that are rap- idly cooled--most often by an expanding gas. Atomization of aluminum is discussed in more detail in the article "Production of Aluminum Powders" in this Volume.
