Applications
- Chemical processing equipment such as liners, vessels, reactors, heat exchangers, and corrosion-resistant process equipment. Zirconium is widely used in chemical process industries because of its corrosion resistance.
- Nuclear industry components, where zirconium alloys are valued for their low neutron absorption and corrosion resistance.
- Heat exchanger parts and other equipment exposed to corrosive media.
- Reactor-related structural parts and fuel-system components, with wording kept broad enough to avoid overclaiming specific cladding use for this product page.
- High-temperature industrial parts where corrosion resistance is more important than extreme heat resistance.
