# Terminology
|
||
|
|
|
||
|
|
- Light alloys --- metals with densities of less than 4.5 gcm$^{-1}$ and typically less than 3
|
||
|
|
characterised by higher strength to weight ratio than typical steel alloys
|
||
|
|
- Cast --- as-cast condition. Cooling rate and grain refiners are key to improve strength and toughness
|
||
|
|
- Wrought --- (rolled, extruded, forged) Properties rely on appropriate heat treatment or working
|
||
|
|
such as precipitation hardening or work hardening
