TYPES OF ALLOYS
METALS
Metals are found in nature forming minerals or in pure state(gold, silver)
The process of extraction,obtention and transformation is called
METALLURGY
OBTENTION PROCESS
1-Metals are obtained from minerals that are found in mines.
OPEN PIT MINES
2-Minerals are separated into
THE GANGE
THE ORE
3-Finally they go through different transformation to produce metals.
UNDERGROUND MINES
PROPERTIES
- Good conductors.
- They have a characteristic shine.
- They are dense and heavy.
PHYSICAL
CHEMICAL
- Ferrous metals get oxidation(iron, steel).
- Non ferrous (copper, aluminium, gold...)
resist better to oxidation.
- Very ductile.
- Very malleable.
- Very resistant to stresses.
MECHANICALS
- Great duability.
- Reciclable.
- Reusable.
ECOLOGICAL
NON-FERROUS
METALS
ALUMINIUM
- Soft, red colour.
- High electrical and thermal conductivity.
- Resist to corrosion.
COPPER
Applications:
Electrical cables and pipes.
- Soft, white colour.
- Malleable and ductile.
- Resists to corrosion.
TIN
- High electric and thermal conductivity.
Applications:
Tinplate (hojalata)/Soft soldering.
Applications:
ZINC
- Blue-grey colour.
- Protects steel from corrosion by galvanization.
Soda cans, bicycles...
Applications:
Galavanized steel:fences, lamppoosts...
LEAD
- Soft and heavy.
- High thermal conductivity.
- Malleable.
Applications:
Batteries, radiation shield
ENVIRONMENTAL IMPACT OF METALS
Metals have great aurability, negclability and are reusable but mining can cause problems such as pollution, large con sumption of resources and landscape degradation.
FERROUS METALS
They contain Iron in its composition.They are:
IRON
Good magnetic properties and very fragile or brittle.
Applications:
Electrical machines.
STEEL
Good mechanical properties.
Applications:
Beams, tools...
FOUNDRY
- Black colour.
- Very brittle and hard.
- Resistant to corrosion.
Applications:
Lampposts, bollards...
