What is a Ferrous Metal?

Ferrous metals contain iron and are magnetic. They are also prone to rust and need a protective finish to prevent corrosion.

Name 3 types of ferrous metals?

1. Cast Iron

2. High Carbon Steel

3. Low Carbon Steel

Name some properties of Cast Iron?

1. Brittle if thin

2. Can be cast in a mould

3. Strong compressive strength

4. Good electrical and thermal conductivity

5. Poor resistance to corrosion

Name some uses for Cast Iron?

1. Gates

2. Manhole Covers

3. Drains

Name some properties of High Carbon Steel?

1. Hard

2. Brittle

3. Less malleable than mild steel

4. Effective electrical and thermal conductor

Name some uses for High Carbon Steel?

1. Tools

2. Screwdrivers

3. Chisels

Name some properties of Low Carbon Steel/ Mild Steel?

1. Ductile

2. Tough

3. Easy to shape, braze and weld

4. Good Conductor of heat and electricity

5. Corrodes easily

Name some uses for Low Carbon Steel/ Mild Steel?

1. Nuts and Bolts

2. Screws

3. Bicycle Frames

4. Car Parts

What is a Non-Ferrous Metal?

Non-ferrous metals do not contain iron and are not magnetic. They do not rust.

Name 2 Non-ferrous metals?

1. Aluminium

2. Copper

Name some properties of Aluminium?

1. Lightweight

2. Malleable

3. Strong

4. Good conductor of heat and electricity

Name some uses of Aluminium?

1. Drinks Cans

2. Cycle frames

3. Saucepans

Name some properties of Copper?

1. Malleable

2. Excellent conductor of electricity and heat

Why is that Copper is good for plumbing and Central heating applications?

It is an excellent conductor of electricity and heat
