Facts
Interesting Facts
  • Bohrium metal is also known as Unnilseptium (Uns) and Nielsbohrium (Ns).
  
  • The main source of Cobalt is as a by-product of copper and nickel metal mining.
  • Cobalt metal can be obtained from other elements like Oxygen, Sulfur and Arsenic.
  • It s also used in electroplating process as it exhibits anti cession properties.

Uses
Uses & Benefits
  • Currently known uses of Bohrium metal are limited to research purpose only.
  
  • Its alloys with aluminum and nickel are used to make powerful magnets.
  • Few other alloys exhibit high-temperature strength and hence they are used in Turbines of Jet and Gas engine.
