Zirconium wire, circle
General Characteristics
Under ordinary conditions, zirconium is a shiny steel-gray metal with a yellowish tint. It is a paramagnetic, heat and corrosion resistant, ductile material. It is obtained from ore concentrates and by remelting zirconium waste. This metal is resistant to aggressive media. It retains its characteristics at high and cryogenic temperatures. Zirconium unusual properties are used for alloying of important alloys and steels. The metal not only imparts zirconium heat and corrosion resistance but also increases technological capability.
Production
Zirconium wire is produced cold drawn and drawn under cold pressure and is distinguished by its hardness and resilience. Soft wire, also called annealed wire, is also produced. Cold drawn wire based on zirconium alloy with 1-2.5% niobium (diameter from 0.9 to 3 mm) after vacuum annealing with etched surface is checked for the absence of pores. Used for windings of superconducting magnets. Zirconium round is alloyed with silicon and other elements to impart strength (e.g. with a niobium additive of 1-2.5%). It can also be rolled from alloy E-635. Round is made cold and hot-formed (hot-pressed), as well as cast and forged. According to the accuracy it can be of high and usual accuracy. Diameter circles are usually from 4.5 to 80 mm. and length up to 7400 mm. It is produced in accordance with GOST under the name "Zirconium and siliconized zirconium bars". It is used in electro-vacuum and special machine engineering.
The wire is usually rolled up to Ø 0.1-3.9 mm.

Iodide zirconium bars are a special type of product. This is the purest zirconium. They are produced by iodide refining of regular zirconium chips. Such bars are used for making electric vacuum devices, absorbers and as electrodes. The rod is only made straight. Regardless of the type, it must withstand a pressure of about 370-440 MPa.
Use
Zirconium wire is used in instrumentation, machine building, nuclear power. It is used in electrical engineering to produce anodes, cathodes and electroplating. It is used for making electrodes for electro-erosion machines where controlled decomposition into elements with the help of current is carried out. Zirconia cathodes are used for electrolytic wear-resistant coatings. Zirconium oxides, nitrides, oxynitrides are applied to cutting edges of tool high-speed steels and hard alloys, on turbine blades, on rubbing parts of gears, shafts, bushings, which increases durability of parts many times. Zirconia corrosion protection spraying is also done with a wire. A thin layer of zirconium is deposited on the parts under vacuum conditions. In recent years, dentistry has begun to use zirconia spraying on dentures. Such wire is an important part of mechanisms that operate in a vacuum. Its constant customers are research physics laboratories and institutes. It is difficult to imagine household and computer equipment without zirconium wire. Biological inertness of this wire allows its use in surgery for ligament suturing and fixation of bone fragments. Among other things, it is used to make jewelry. Such products are beautiful, elegant, evidence of good taste, they are very highly valued at international exhibitions. As zirconium retains radiation, has a narrow cross-section of thermal neutron capture and resistance to aggressive environments - it is used in the nuclear power industry. Zirconium wire is used as a filler element for welding tubular parts of fuel rods. It should be remembered that up to 300 °C this metal does not react with superheated steam, but above. 700 °C, an exothermic parazirconium reaction may start that can cause an accident in water-cooled nuclear reactors.
Storage and Transportation
Coils of zirconium wire are packed with paper and placed in a wooden crate lined with three layers of polyethylene film. Packing should exclude shifting inside the package during transportation. The packaging is marked in accordance with
