Principal applications

 
     
 

These powders have very high hardness and outstanding abrasion resistance. These are used to manufacture diamond tools for cutting of very abrasive materials.

 
     
 

F.T.C. is also useful to :

 
 
  1. Manufacture self lubricating sintered bearing.
  2. Manufacture contact material of current flow performance in arc resistance, adhesion resistance & contact resistance.
  3. Manufacture brushes application in electric motors & generators.
  4. Friction material for brakes.
