Interesting Facts
- The only metal which burns in Nitrogen is Titanium.
- Titanium is also known as corrosion resistant metal.
  
- 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.
