Aluminum Powder
Aluminum powder is during in the powder metallurgy process to produce sintered aluminum products. Powder metallurgy, often denoted as P/M, is used to form a solid product by pressing metal powder into a coherent mass without heating the metal to its melting point.
Unlike aluminum products formed by traditional metalworking processes, aluminum powder used in P/M provides the final product with a high concentration of oxide. This protective oxide layer increases the metal's resistance to corrosion and provides added durability.
Aluminum is a chemical element with the atomic number thirteen. It is silver and ductile and often desired because it is lightweight. Aluminum powder is widely used in silver paint and in pyrotechnics. Some cosmetics, especially those applied to the eye area, also contain aluminum powder. Sintered aluminum alloys are being used more and more often for antifriction purposes in which wear resistance is crucial.
