1 of 4
- Magnetic: Emits a magnetic field that can attract other magnetic materials. Most ferrous materials are magnetic.
- Conductor of heat: Heat encounters little resistance as it goes through the material.
- Conductor of electricity: Electricity encounters little resistance as it travels through the material.
- Resistant to corrosion: The material will not corrode (rust).
- Ductility: The ability of a material to be drawn or stretched into thinner, smaller sections without snapping.
- Elasticity: The ability to return to the original shape after being deformed.

- Compressive Strength: The ability of a material to withstand being squashed.
- Toughness: The ability to withstand sudden shock loading (dropping it).
- Durability: The ability to withstand wear, pressure or damage.
- Shear: The ability of a material to withstand being pulled or slid apart (a joint).
3 of 4
- Malleability: The ability of a material to be changed into a different shape.
- Fluidity: When melted the metal becomes very liquid - good for casting.
