aluminum, the secondmost plentiful metallic element on earth, became an economic competitor in engineering applications as recently as the end of the 19th century.
aluminum casting alloys are the most versatile of all common foundry alloys and generally have the highest castability ratings. As casting materials, aluminum alloys have the following favorable characteristics:
· good fluidity for filling thin sections.
· low melting point relative to those required for many other metals.
· rapid heat transfer from the molten aluminum to the mold, providing shorter casting cycles.
· chemical stability.
· good as-cast surface finish with lustrous surfaces and little or no blemishes.
