Zircaloy-4 Round Rod

Advantages of Zircaloy-4

Excellent Corrosion Resistance

Zircaloy-4 is stable in high temperature, high pressure, steam and salt water environments and is not easily oxidized or corroded.

Excellent Mechanical Properties

High strength and good ductility enable it to be used in complex working conditions, while being easy to process and weld.

Low Neutron Absorption Cross Section

As a nuclear industry material, its low neutron absorption cross section helps improve the fuel utilization efficiency of the reactor.

Good Thermal Conductivity

Ensures stable operation of nuclear fuel in the reactor and reduces the impact of thermal stress on the material.
