The major characteristics of the 5xxx series are:
*Non-heat-treatable sand,permanent mold,and die castings
*Tougher to cast;provides good finishing characteristics
*Excellent corrosion resistance,machinability,and surface appearance
*Approximate ultimate tensile strength range:120 to 175 MPa(17-25ksi)The common feature of this group of alloys is good resistance to corrosion.Primary use alloys 5120 and 5140 have medium strength and good elongation and are suitable for components exposed to seawater or to other similar corrosive environments.These alloys often are used for door and window fittings,which can be decoratively anodized to give a metallic finish or provide a wide range of colors.Their castability is inferior to that of the aluminum-silicon alloys because of its magnesium content and consequently,long freezing range.For the reason,it tends to be replaced by 3550.Which has long been used for similar applications.For die castings where decorative anodizing is particularly important,alloy 5200 is quite suitable.
Building and construction markets
Building and construction encompasses those markets in which architectural and /or structural requirements come together.Such applications include residential housing,commercial storefronts and structures,conference centers and areas(i.e.,long roof bay requirements),highway bridges and roadside structures,and a variety of holding tanks and chemical structures(also considered under “chemical and petroleum markets”).Among the choices are:
*Bridges and other highway structures:6061 and 6063 extrusions,5083,5086 and 5454 plate.
