Zirconium wire, zirconium round

Zirconium wire, zirconium round

Zirconium under normal conditions is a steel-gray lustrous metal with a yellowish tinge. It is paramagnetic, heat-resistant and corrosion-resistant metal, malleable and ductile. It is mined from an ore or concentrate by melting of zirconium waste. Zirconium is resistant to influence of aggressive environment. In the conditions of cryogenic and high temperatures the Zirconia retains its properties. Extraordinary properties of zirconium are used in order to responsible alloying steels and alloys, which he gives as heat-resistance and resistant to corrosion, and also improves manufacturability.

Zirconium wire is produced by cold rolling with a diameter of 0.7 — 4.0 mm of zirconium alloys. In its composition, the wire contains from 1% to 2.5% of niobium is another popular material in the production of channels and fuel elements for nuclear reactors, where it is used for welding tubular parts. Also produced soft wire, also called annealed. Cold drawn wire used for the windings in superconducting magnets. Zirconium round legerrette using silicon and other elements to impart high strength (for example, the additive of niobium 1−2,5%).

The wire is also rolled from alloy grade e-635. Zirconium round produce hot (i.e. hot-pressed) and cold, as well as forged and molded. Accuracy of the production range can be normal and high accuracy. Its diameter typically is between 4.5 and 80 mm, maximum length of 7400 mm. Round cubic Zirconia made in accordance with the standards GOST — «Zirconium bars and rods, of silicon-zirconium». They are applied in special and in vacuum engineering. Rods made of zirconium godenovo are special products and represent the most pure zirconium. It is obtained by refining godenovo conventional zirconium shavings. Rods of this type serve in the production of vacuum devices, as electrodes and absorbers. The rod is made just right, and it needs to withstand the pressure depending on the type of order 370−440 MPa.


Zirconium wire is used in machine building, instrument making, nuclear energy. In electrical engineering zirconium wire is used for manufacturing cathodes, anodes and electroplating. Wire producing electrodes for EDM, where it is driven with a current decomposition into the elements. Cathodes of zirconium shall be applied to wear-resistant coatings by electrolytic deposition. Applied oxynitride Zirconia, nitrides, oxides on the cutting edges of high speed tool steels and hard metals, friction parts in the transmission gear, turbine blades, bushings, shafts, greatly increasing the durability of the parts.

Zirconium coating that protects against corrosion, is being implemented with the help of wire. Zirconia thin layer is applied in vacuum to the details. In dentistry recently began to use zirconium-plated dentures. This wire is an important part of the mechanisms operating in vacuum. Its constant clients are the physical research laboratory, institutes. It is hard to imagine without zirconium wire of computer and household appliances. Its biological inertness allows to use it in surgery for fixation of bone fragments and stapling ligaments. Zirconium wire is used in the production of jewelry. Such jewelry is elegant, beautiful, show good taste, and are very much appreciated at international presentations and exhibitions. Due to the fact that zirconium is able to delay radiation, and has a narrow capture cross section for thermal neutrons and resistance to aggressive environments, which is used in nuclear power.

Zirconium wire serves as a filler element for welding tubular parts in the fuel channels of the fuel rod. It should be remembered that up to 300 °C the zirconium is not included in the reaction with superheated steam, however, at temperatures above 700 °C may occur paraseraya exothermic reaction, is fraught with a nuclear reactor water coolant accident.

Transport and storage

Bay of zirconium wire Packed with paper and placed in a wooden box which is lined with 3 layers of polyethylene film. It is necessary that the packaging is excluded during transport, movement within the container. Her marking is made according to GOST 14192−96 with indication of manufacturer, gross weight, net weight, alloy types ' of customer and heat number. Bars and wire may be transported by any means of transport. It is stored indoors, protected against moisture, dust, chemically active substances.
