  • Tubular products
    Patent number: 4028785
    Abstract: A bimetallic tube comprising a copper-base alloy and a reactive metal such as titanium, is produced by assembling concentrically a tubular member of each of such materials and interposing a layer of copper, nickel or silver between them, forming a bond between the reactive metal and the copper, nickel or silver and extruding the assembly. The bimetallic tube is useful for heat exchange purposes when corrosive fluids are involved and has better heat transfer properties than an all-reactive metal tube.
