Zirconium is considered quite sensitive due to the application in nuclear reactors. However, Zr is highly corrosion resistance with its dense oxidized surface, the same as Ti but even better. There are about 2% of Hf in Zirconium by nature, and its considered harmless for most of applications except for the 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.
