METALS
-A solid material which is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity .
-Ferrous:
- Vehicle scrap metal
- Demolition Site scrap metal
- Metal offcuts from manufacturing industries
-Non-ferrous:
- Aluminium & Aluminium Alloys
- Copper
- Brass
Metals: | |
Strong | |
Malleable and ductile | |
React with oxygen to form basic oxides | |
Sonorous | |
High melting and boiling points | |
Good conductors of electricity | |
Good conductors of heat | |
Mainly solids at room temp. Exception mercury - liquid at room temp. | |
Shiny when polished | |
When they form ions, the ions are positive | |
High densit |
-Alloys:
·Steel, a combination of iron (metal) and carbon (non-metal)
·Bronze, a combination of cooper (metal) and tin (metal)
·Brass, a mixture of copper (metal) and zinc (metal)
-New materials:
A superalloy, or high-performance alloy, is an alloy that exhibits several key characteristics: excellent mechanical strength, resistance to thermal creep deformation, good surface stability, and resistance to corrosion or oxidation
