Zirconium Alloys. Zirconium alloys have been chosen for various nuclear applications due to several properties: low thermal neutron capture cross section together with good behaviour in high temperature water were probably the main reasons for their use as clad materials in light water reactors, while the very high resistance to corrosion in specific nitric acid conditions together with good ...
The main use for zirconium sponge is in the nuclear industry where a minimum content of hafnium is needed. It features in nuclear and non-nuclear grades (of which about 70% is nuclear grade) and is used to produce zirconium alloys for nuclear reactor components, such as cladding for fuel rods.

Zirconium 702 is a commercially pure Zirconium. Zirconium is a reactive metal that has a high affinity for oxygen resulting in the formation of a protective oxide layer in air at room temperature. This protective oxide gives Zirconium alloys their superior corrosion resistance. This oxide layer can be enhanced through a heat treating process.
19-09-2019· Sandvik Zr 702 is a zirconium grade characterized by immunity to stress corrosion cracking and high resistance to pitting and crevice corrosion. The grade has very good corrosion resistance in most organic acids, excellent corrosion resistance in mineral acids, good corrosion resistance in strong alkalis and moderate mechanical strength.
Zirconium Machining & Forming Operations INTRODUCTION Zirconium is a hard, shiny, grayish white metal. With its superior corrosion resistance capabilities, it has increasingly become the material of choice in the fabrication of chemical processing equipment. For non- nuclear applications, zirconium has two main alloys:
Zirconium’s strength, corrosion resistance and durability make it ideal for use in pipes, fittings and heat exchangers, steel alloys, colored glazes, bricks, ceramics, abrasives, flashbulbs, lamp filaments, artificial gemstones and some deodorants.
Zirconium alloys are solid solutions of zirconium or other metals, a common subgroup having the trade mark Zircaloy. Zirconium has very low absorption cross-section of thermal neutrons, high hardness, ductility and corrosion resistance.
Zirconium shows excellent corrosion resistance to all concentrations of hydrochloric acid even at temperatures exceeding the normal boiling point. Since zirconium is one of higher priced alloys applied in the chemical process industry, it is used only where service conditions necessitate its selection.
Generally, Mg alloys contain one or two primary alloying elements. The Mg alloys are mainly based on three binary systems: Mg-Al, Mg-Zn and Mg-Zr. The magnesium alloys without zirconium show a strong tendency for grain growth. Non-alloy magnesium can undergo cold deformation up to 5-10%.
