The Difference Between The Zirconium R60705 And The Zirconium R60702
Zirconium (atomic symbol: Zr, atomic number: 40) is a Block D, Group 4, Period 5 element with an atomic weight of 91.224. The number of electrons in each of Zirconium's shells is 2, 8, 18, 10, 2 and its electron configuration is [Kr]4d2 5s2. The zirconium atom has a radius of 160 pm and a Van der Waals radius of 186 pm. Zirconium was discovered by Martin Heinrich Klaproth in 1789 and first isolated by Jöns Jakob Berzelius in 1824. In its elemental form, zirconium has a silvery-white appearance that is similar to titanium. Zirconium's principal mineral is zircon (zirconium silicate). Elemental Zirconium is commercially produced as a byproduct of titanium and tin mining and has many applications as an opacifier and a refractory material. It is not found in nature as a free element. The name zirconium comes from the mineral zircon, the most important source of zirconium, and from the Persian word argue, meaning gold-like.
Zirconium Plate Applications
Zirconium plate provides the strong corrosion resistance needed for tough industrial applications, particularly in specialized chemical environments. Both materials maintain their strength and integrity in organic and mineral acids used in power plants, petroleum production, and subsea environments. Common plate applications include:
Specialty metal fabrication
Chemical storage tanks and towers
Marine environments including hardware for ships and vessels
Heat exchanger tube sheets
Piping, tubing, fittings, and fixtures for extracting and processing plants
Zirconium sheets from LINKUN have a number of advantages over sheets of other metals. For starters, zirconium is quite soft and malleable at room temperature and pressure, making our zirconium sheet easy to work with. Pure elemental zirconium also has a very high melting point, making it ideal for use in high-temperature applications like refractories, furnaces, and cladding on jet engines and nuclear reactors.
Resistant to corrosion by acids, alkalis, and solvents, and even able to resist the corrosion caused by seawater, zirconium sheet is the ideal choice for cladding when caustic environments and high temperatures must be contended with.
The Difference Between the Zirconium R60705 and the Zirconium R60702
1. Chemical Composition
R60705 (Zr702): R60705 is commercially pure zirconium, containing trace amounts of iron (Fe) and chromium (Cr) with minimal alloying elements. Comprising over 99.2% zirconium, this grade offers exceptional corrosion resistance.
R60702 (Zr705): R60702, on the other hand, is a zirconium alloy with niobium (Nb) content typically ranging from 2.0% to 3.0%. The addition of niobium enhances both the strength and corrosion resistance of this alloy.
2. Mechanical Properties
R60705: This grade has lower mechanical strength but demonstrates excellent ductility and toughness, making it suitable for applications where high ductility is required without the need for enhanced strength.
R60702: With the addition of niobium, R60702 has greater strength, particularly at elevated temperatures, providing improved stability and durability under high-temperature conditions. This makes it ideal for applications that require high strength in demanding environments.
3. Corrosion Resistance
Both grades exhibit outstanding corrosion resistance; however, R60702 performs better in more aggressive corrosive environments, thanks to niobium's beneficial effect on corrosion resistance.
4. Application Scenarios
R60705: Given its excellent corrosion resistance and ductility, R60705 is commonly used in environments that demand high corrosion resistance, such as nuclear reactors and chemical processing equipment.
R60702: With its higher strength and improved high-temperature performance, R60702 is better suited for applications with higher mechanical demands, such as certain components in the nuclear industry requiring higher pressure resistance, as well as aerospace applications.
