- Ferrous-Metals containing Carbon and Iron
- Non-Ferrous-Metals not containing Iron
- Alloys-Mixture of two or more metals
- Non Alloys-One metal
Ferrous Alloys-A mix of two or more metals. At least one of which contains Iron or Carbon.
Non-Ferrous Alloys-Mixture of two or more metals not containing Iron.
Ferrous:
Mild Steel-Quite strong/Cheap but rusts easily and can't be hardened or tempered.
High Carbon Steel-Harder than Mild Steel. Can be hardened and tempered.
Non-Ferrous:
Aluminium-Light weight/corrosion resistant. Expensive, Not nearly as strong as Steel.
Brass-Quite strong/corrosion resistant, Malleable, Ductile/Looks good
Copper-Relatively soft, Malleable, Ductile, Good conductor of electricity.
25% of the Earths crust is Metal Ore
- Aluminium is most common, followed by iron
- In general, the more rare it is the more expensive it is
- Iron(Ferrite) is converted from its ore by heating. The resulting impurities(Slag) are removed from the furnace leaving a soft, grayish metal once it has cooled. It is rarely used without combining it with Carbon thus giving it a greater strength(Steel)
- Non-Ferrous Metals-This group of metals contains-Aluminium, Copper, Tin, Lead, Zinc as precious metals such as Silver, Gold and Platinum.
