Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.


Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industries. They’re used in steam generator tubing in the nuclear power industry, in high-temperature aircraft systems, and in oil and gas extraction programs where corrosion-, pressure- and temperature-resistant tubing is required. Their corrosion resistance also makes them useful in desalination equipment.
