Chemical Properties

  •  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.

Mechanical Strengths

  • 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).

Mechanical Properties

  • Malleability:  The ability of a material to be changed into a different shape.
  • Fluidity: When melted the metal becomes very liquid - good for casting.
