2 Facts
2.1 Interesting Facts
- Manganese is an essential trace element in all forms of life.
- Manganese metal oxidizes very easily, but it does not fuse that easily.
- Vanadium is a highly reactive metal, hence it is not found free in nature.
- Vanadium can be found in almost 65 different types of minerals.

3 Uses
3.1 Uses & Benefits
- This metal is very brittle hence it mostly not used as a pure metal, but its alloys are very useful
- Its alloy Manganese steel is extremely strong and used in railway tracks, safes, prison bars and riffle barrels.
- Its ally with steel is used very tough and hence it is used in armor plates, axles, piston rods, tools and crankshafts.
-
Its oxide is used as pigments for glass and ceramics.
