Zirconium is considered quite sensitive due to its application in nuclear reactors. However, Zr is highly corrosion resistant with its dense oxidized surface, the same as Ti but even better. There are about 2% of Hf in Zirconium by nature, and it's considered harmless for most of the applications except for nuclear projects. Separation of Zr and Hf is quite difficult and usually, people don't conduct the separation for commercial use.

The high purity 99.95% zirconium crystal bar with low hafnium can be used in nuclear reactors. The zirconium crystal bar is the raw materials of high purity of zirconium sheet, zirconium wire, and zirconium sputtering target.
