In the machining world, Nonferrous refers to metals that do not contain any Iron (Fe). Non-ferrous have inferior mechanical properties when compared to steel and usually cost more per Kg. They are used when one of their specific properties are needed.
The main groups of nonferrous metals are:
- Aluminum – Used to reduce weight and chip machining costs.
- Copper – Used due to its high conductivity.
- Brass – High machinability
- Plastics – Low-friction, high-wear resistance, electrical insulation, chemical resistance to solvents.
