- Metals
- Ferrous metals
- containing mostly iron and carbon
- magnetic and will rust
- examples
- low carbon steel
- ductile
- high tensile strength
- malleable
- poor resistance to corrosion
- high melting point
- nuts, bolts and screws
- car bodies
- washers
- medium carbon steel
- hard
- less ductile than low carbon steel
- malleable
- tough
- springs
- garden tools
- cast iron
- hard outer skin
- brittle core
