metal - Coggle Diagram
metal
non-ferrous (non-ion
Aluminium
properties
light
recyclable
conducts heat and electricity
soft and malleable
uses
foils
cans
ladders
windows
aircraft
zinc
used to coat steel- galvanzing
highly protective on steel - resists rust oxidisation
copper
properties
ductile
malleable
resists corrosion
excellent conductor of electricity
uses of copper
electrical cables
because it conducts electricity so well
tin
used for alloyed
low melting point
pewter is made from tin
good for casting / solder
lead
soft and malleable
used for car batteries / old plumbing / roof flashing
can be poisonous - so not used so much for plumbing anymore
metals come from the earth in the form of ORE
blast furnace
molten iron
ferrous (ion)
All ferrous metal rust (oxidation)
mild steel
alloy of iron and carbon (99.7% Iron 0.3% carbon)
welds very easily
needs protecting to stop rust - paint
ductile, tough, malleable
high carbon 4%
very hard wearing but brittle
other steel
stainless steel
resistant to rust
cutlery, sink, surgical equipment
contains chromium (18%)
carbon steel
much harder - so can be used for tools
Higher % of carbon (0.4-1.4%)
prone to rusting
Alloys
A mixture of 2 or more metals
Improves the properties of the materials
strength
strength of compression
strength in tension / tensile
resistant to corrosion
Dualumin
aluminium, copper, manganese
strong
durable
light
