Nitrogen trifluoride construction materials

At temperatures less than 482°F (250°C), nitrogen trifluoride has a reactivity similar to that of oxygen and is relatively inert to most materials of construction. At ambient temperatures, brass, aluminum, copper, steel, and stainless steels can be used because corrosion rates of less than 0.1 mil/yr. at 160°F (7l.l°C) have been determined for these materials. Nitrogen trifluoride is also compatible with fluorinated materials such as Teflon at ambient temperatures. 

At increased temperatures and pressures, nitrogen trifluoride s reactivity increases becoming more like that of fluorine, with nickel and Monel being the preferred materials of construction.
