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.
*Storefronts,curtain wall:6063 extrusions
*Building sheet,siding:3005,3105 and 5005 sheet
*Arena and convention center roofs:6061 extrusions with
5*** alloy sheet panels
*Residential housing structures:6063 extrusions
*Architectural trim:5257,5657,6463
*Composite wall panels:5*** alloy sheet plus expanded
polymers
