Description of Zirconium Wire
Zirconium, represented by the symbol Zr and atomic number 40, is a lustrous, gray-white metal known for its high strength, corrosion resistance, and low thermal conductivity. It is highly valued in various industries, including nuclear energy, chemical processing, and aerospace, due to its ability to withstand extreme conditions. Zirconium is often found in the form of zirconium alloys, which enhance its mechanical properties, making it suitable for applications such as reactor cores, heat exchangers, and dental implants.
