What are ferrous metals?
They are metals containing iron
Common features for ferrous metals.
-They are inexpensive to extract
-They need to be processed to produce
pure iron and used to make alloys.
What is an alloy?
It is a mixture of two or more chemical elements- the primary element is a metal
Iron alloys are created by adding...
What is Pure iron?
It is an iron alloy in which the concentration of carbon is between 0,008% and 0,03%.
What is steel?
It is an iron alloy in which the concentration of carbon is between 0,03% and 1,76%.
What is Cast iron?
It is an iron alloy in which the concentration of carbon is between 1,76% and 6,67%.
Advantages for Pure Iron
It has very high magnetic properties, so it is attracted by magnets
Disadvantages for Pure Iron
- it corrodes easily
- it has a high melting point
- it is brittle
- it is difficult to machine.
What is Pure Iron used for?
It is used for electrical and electronic components.
Advantages for Cast Iron
-It is extremely hard , so does not scratch
- It is extremely resistant, so does not distort on heat
- It doesn't rust
What are the disadvantages of Cast Iron?
It's very brittle
What is Cast Iron used for?
It is used for machinery parts, pistons,
street lamps, drain covers...
Advantages for Steel
-It has better mechanical properties than pure or cast iron because it is very hard and strong.
- By adding chemical elements it is possible to improve or obtain certain properties for steel
Alloy: Steel plus manganese
It makes the alloy harder and heat-resistant.
Alloy Chrome plus Nickel plus Steel
They are used to make stainless-steel.
What is the main advantage of stainless steel?
It doesn't rust
What is a non-ferrous metal?
A metal that does not contain iron
Brass is an alloy of which 2 metals?
Copper and zinc
What are some of the advantages of non-ferrous metals over ferrous metals?
They are lighter and they don't rust.
What are some disadvantages of non-ferrous metals over ferrous metals?
They aren't as strong and are usually more expensive.
Classification of non-ferrous metals according to its density
Ultralight, light and heavy metals.
Exemples of heavy metals

What is tin used for?
It is used for food packaging
What is copper used for?
It is used for electrical wires, pipes, radiators
What is bronze used for?
It is used for church bells, boat propellers, gears
What is brass used for?
It is used for plumbing, turbines...
What is lead used for?
It is used for batteries
What is aluminium used for?
It is used for planes, cars, high voltage power lines, kitchen tools and drink cans.
What is titanium used for?
