Zirconium Zirconium Alloy Tubes for Nuclear Industry

The best use of Zirconium alloys tubes is for structural material for nuclear reactors due to the low thermal neutron absorption. Because zirconium has a lower absorption of neutrons than most metals it is the material of choice to improve reactor efficiency.
