Material – Zirconium – Ankuro
In contrast, the nuclear industry requires zirconium alloys with the lowest possible amount of hafnium. Here, the material Zirkaloy with a hafnium content of 0.1% serves as a fuel element sleeve tube, in which a low neutron capture cross-section is required in order to achieve a maximum yield at the desired chain reaction of the fuel uranium.
zirconium hafnium title - klimaatwebsite.be
Zirconium alloy - Wikipedia. Commercial non-nuclear grade zirconium typically contains 1–5% of hafnium, whose neutron absorption cross-section is 600x that of zirconiumHafnium must therefore be almost entirely removed (reduced to 002% of the alloy) for reactor applications. 【Get Price】

About Zirconium | Zirconium 702 & 705 Information
As a commercially pure grade, zirconium 702 offers excellent corrosion protection with resistance to stress-corrosion cracking and crevice corrosion. It’s often used for stone processing. Alloyed with 2 to 3 percent Columbium, zirconium 705 is significantly stronger and more ductile than zirconium 702 with almost equal corrosion resistance, making it the alloy of choice for most zirconium ...
