With the density of 6.51 g/cm³, lighter than steel whose density
is 7.8 g/cm³, which is an advantage for reaction structural materi-
als. And with the high melting point 1852 °C to ensure the heat s-
tability under the reactor pile working temperature. The low coef-
ficient thermal expansion approximately 5.8 × 10⁻⁶ /K (20-400°C)
which means the scale change under the heating and cooling pr-
ocessing. The heat conductivity is about14-21 W/(m·K)(20-400°C),
with the medium heat conductivity effectively transmit the fuel
heat to the coolant. Elasticity modulus is 99GPa which is lower
than steel and with the medium rigidity. Tensile strength ≥
415MPa under the annealing state with enough mechanical
property to endure the runtime reaction pile mechanical and
coolant stress. Elongation ≥ 20% under annealing state with
excellent plasticity to manufacture elbow pipe,expand tube with a
certain deformation.
