Unsurpassed Corrosion Resistance: 

The aluminized steel tubing is heat treated up to 1400°F where
the aluminum coating (supplied by aluminized steel) is fused into the tubing. The heat
treating process forms a homogenous layer of iron-aluminum (Fe-Al), which is
extremely oxidization resistant.

Higher Operating Temperatures:

This protective coating of the homogeneous alloy (Fe-Al) can withstand higher
operating temperatures than other conventional tube materials (as certified by Armco
Research and Technology Laboratories). The maximum operating emitter tube
temperature is 1250°F.

Higher Surface Emissivity:

An additional benefit of the heat treating process is a greatly enhanced external surface
emissivity as well as improved internal surface absorptivity.
