It is simply to divide aluminum and aluminum alloys into two categories: wrought aluminium alloys and cast aluminum alloys. Wrought aluminium alloys contain lower percentage of elements, about less than 4%. Cast aluminum alloys contain the same chemical composition but has greater amounts. In the same temperature range( 520 to 590℃), the cast aluminum alloys undergo a thoroughly chemical properties while wrought aluminum alloys still remain the mechanical properties and remain ductile.
Aluminum, a silvery white, soft metal, kitchen utensils past appeared more at home, and now we are all made of stainless steel instead of, but in the home circuit wires, smallpox and a variety of household hardware supplies still a lot of use, etc., today we come to understand the density of aluminum, aluminum density is the number density of aluminum understand how we count down? How much of the aluminum density?
