However, this much can be stated authorita tively: there are three Revere Metals which deserve tpecisl consideration in esses of limited or unsatis factory tube life. Here they are: Cupro-Nickol, 30%. Withstands high operating temperatures. A tenocleus surface film forms on (hit rnelof, which resists impingement attack and erosion, soft wafer, and wafers containing organic material. Widely used in marine and *eoboord Installations, the tropics and tub! topics. ' Cupro-Nlckel, 20%. Similar to Cupro-Nickel, 30%, but lower in price end somewhat feu resistant to certain typos of corrosion. favafon (Aluminum Brats). This Revere MetaI contains a small proportion of aluminum, which ,0W* F,bm,ry IMS gives it a long life in applications where watar velocities ore high or water Is saline. The film formed on this tube ft tenacious and self-healing, rendering It highly resistant to impingement attock.
