Zirconium is a widely used metal in various applications such as nuclear reactors, chemical processing, and aerospace. There are two common types of zirconium alloys: zirconium 702 and 705.
Zirconium 702 is a commercially pure zirconium alloy that contains 99.2% zirconium, 0.2% hydrogen, 0.1% iron, 0.005% chromium, and other trace elements. It has excellent corrosion resistance, high strength, and good weldability, making it suitable for use in nuclear reactors, chemical processing equipment, and medical devices.
Zirconium 705 is an alloy that contains 95.5% zirconium, 2% niobium, 1% tantalum, and other trace elements. It has better mechanical properties and radiation resistance than zirconium 702, which allows for its use in more demanding environments such as nuclear fuel cladding and fuel assemblies.
In summary, both zirconium 702 and 705 are excellent materials with unique properties suitable for specific applications. While zirconium 702 is suitable for general use in chemical processing and medical devices, zirconium 705 is ideal for more demanding environments such as nuclear fuel cladding and fuel assemblies.
