Aluminum Alloy Production

Author:Shanghai Yika Addtime:2017/6/16

Aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include, silicon, copper, magnesium, manganese and zinc etc. at levels that combined may make up as much as 16 percent of the alloy by weight.  Aluminum alloys are assigned a four-digit number, in which the first digit identifies a general class, or series, characterized by its main alloying elements. 

Some aluminum alloys are strengthened by solution heat-treating and then quenching, or rapid cooling.  Heat treating takes the solid, alloyed metal and heats it to a specific point.  The alloy elements, called solute, are homogeneously distributed with the aluminum putting them in a solid solution.  The alloy is subsequently quenched, or rapidly cooled, which freezes the solute atoms in place.  The solute atoms consequently combine into a finely distributed precipitate to the aluminum alloy production.
