Metals - Coggle Diagram
Metals
Non- Ferrous Metals (No Iron)
Aluminium
Properties
Soft and malleable
Conducts heat and electricity
Light
Recycleable
Uses
Cans
Ladders
Windows
Aircraft
Foil
Zinc
Used to coat steel (galvanizing)
highly protecting on steel - resists rust / oxidisation
Tin
Used for alloys
Low melting point
Pewter is made from tin
Good for casting / Soldering
Lead
Soft and Malleable
Used for car batteries, old plumbing, and roof flashing
can be poisonous so not used so much for plumbing anymore
Copper
properties
excellent conductor of electricity
resists corrosion
ductile
malleable
Uses
Electrical Cables
Because it conducts electricity so well
Ferrous Metals
Cast Iron
High Carbon 4%
Very hard wearing - but brittle
Mild Steel
Welds Very Easily
Alloy of Iron and Carbon (99.7% Iron 0.3% Carbon)
Ductile, tough, malleable
Need protection to stop rust - paint
Other Steel
Stainless Steel
Resistant to Rust
Cutlery, Sinks, Surgical Equipment
Contains Chromium (18%)
Carbon Steel
Much Harder - so can be use for tools
Higher % of carbon (0.7 - 1.4% )
Prone to rusting
Contains Iron
All ferrous metals rust (Oxidation)
Metals come from the earth in the form of ORE
Blast Furnace
Molten Iron
Alloys
A mixture of 2 or more metals
Improves the properties of metals
Durable
Appearance
resistant to corrosion
Duralumin
Aluminum, Copper, Manganese
Light
Durable
Strong
Brass
Mixture of copper - 60% and zinc - 40%
Properties
Resistant to Corrosion
Conducts electricity
Uses
Plumbing Fittings
Boat Fittings
Musical instruments
strength
strength in tension/ tensile
strength in compression
