High-purity zirconium wire has very good thermal conductivity, and the response of thermal expansion, cooling, and contraction is small during operation. The good electrical conductivity of zirconium wire has become an important material in the electronic power equipment manufacturing industry, and of course, it is also fully utilized in other industries. Since the molybdenum plate can withstand 2900 degrees in a vacuum, zirconium wire is currently the most widely used heat conduction material in the spacecraft industry.
Zirconium wire is a rare metal with amazing anti-corrosion properties, extremely high melting point, ultra-high hardness, and strength, and is widely used in aerospace, military, nuclear reactions, and nuclear energy fields. The corrosion-resistant and high-temperature-resistant titanium products used in this "Shen 6" are far less resistant to corrosion than zirconium. Above, so zirconium is also resistant to photo flash and corrosion-resistant containers and piping, especially hydrochloric and sulfuric acid. Zirconium chemicals can act as crosslinkers for polymers. As common products of zirconium alloy materials, zirconium wire and zirconium rod have strong corrosion resistance and high-temperature resistance and have the following unique chemical composition and physical properties.
1. The chemical composition of zirconium wire
The chemical composition and room temperature mechanical properties of zirconium wire are shown in Table 1. The elastic modulus of zirconium wire and alloy decreases rapidly with the increase in temperature, and the specific gravity is smaller than that of steel. Represents the average value of longitudinal and transverse properties at room temperature, yield strength and elongation are measured at 0.2% permanent deformation, with elastic-plastic deformation. In addition, some properties are affected by orientation. These properties include thermal expansion, yield strength, ultimate tensile strength, elongation, notch toughness, flexural plasticity, and vary to varying degrees with direction. Ductility increases significantly with increasing temperature.
2. Physical properties of zirconium wire
If the elastic modulus is low, the welding stress is small, the melting point is high, higher welding line energy is required, the linear expansion coefficient is small, the welding deformation is small, and the welding part with high thermal conductivity dissipates heat well, and the specific heat is low, the absorbed heat of the welding part is small. If the surface tension is large, the zirconium wire is an active metal and has a high affinity for oxygen, so a protective oxide film is formed in the air at room temperature. Through the oxide film, the corrosion resistance of zirconium and its alloys is excellent. Zirconium, which has excellent corrosion resistance, is highly resistant to many sheets of etching media, along with good mechanical and heat transfer properties, as well as significant cost advantages.
Industrial zirconium wire is widely used in various types of corrosion-resistant process equipment, mainly used in pressure vessels, heat exchangers, pipes, tanks, shafts, mixers, and other mechanical equipment and valves, pumps, sprayers, trays, mist eliminators, and tars According to statistics, only the left and right objects are processed into the shape of zirconium (or sponge zirconium) and then processed into zirconium alloys, which are used in nuclear fuel assemblies or industrial fields. In terms of processing difficulty, science, and technology, the zirconium industry chain is the most high-end.
