Bimetallic tube is composed of two different materials: usually inner material is a corrosion resistant alloy (copper, aluminium-brass, titanium) whereas the outer material is a high-stress resistant alloy (stainless steel, carbon steel, titanium). It is, however, possible to manufacture bimetallic tubes with any material combination.

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.
