Bimetallic tube is composed of two different materials - usually inner material is a corrosion resistant alloy (copper, aluminum brass or Cupro nickel) whereas the outer material is a high-stress resistant alloy (Brass, stainless steel or carbon steel). It is, however, possible to manufacture bimetallic tubes with any material combination as per the requirement & availability. In applications with high pressures and corrosive conditions, bimetallic tube permits a large economical savings in comparison with a tube made of a single alloy, since the use of precious materials is reduced to the minimum.
