aluminum, also known as architectural aluminum, provides excellent corrosion resistance and good weldability
Meets ASTM B221 specifications
Unpolished (mill) surface has no finish
Extruded into the shape by compressing metal and pushing it through a die
Heat treated for increased strength
Aluminum alloys are lightweight compared to steel, brass, and copper, and have high strength-to-weight ratios.
They offer good corrosion resistance and conductivity of heat and electricity, as well as moderate formability and machinability
