What are ferrous metals
Metals that contain iron
Is iron relatively soft
Yes
How can ferrous metals, or steels be made harder
By adding carbon
What are properties of cast iron
Cost effective
Heavy
Rigid and strong in compression
Casts and machines well
Maintains shapes and properties well
brittle core
What are non ferrous metals
Metals that do not contain iron
What is the most widely used non ferrous metal
Aluminium
Give some properties or aluminium
Lightweight
Ductile
Malleable
Conducitve
Corrzive Resitant
Used in weding
Higj eneegry to extract
What are some pros of mild steel(4)
Tough
Ductile
Malleable
Good tensile strength
What are some cons or mild steel
Poor corrosion resistance
Cannot be hardened except for case hardening
Where would mild steel be used
nuts, botls, screws, car bodies
What are some pros of high carbon steel
High resistance to wear
What are some cons of high carbon steel
Poor resistance to corrosion
Brittle
Where would high carbon steels be used
Hand and machine cutting tools due the their ability to retain sharp edges
What are some properties of stainless steels
Tough hard, corrzive resiatnt
Talk about zinc
Zinc is used genurally to protect other things, done by galvanising
Talk about copper
Ductile
Malleable
Tough
corrsoive resiatnt
condiuvite
can eb sodliered and brased
Talk about tin
Tin is generally used for protections of things like foods, it is used in soldering
Talk about tungsten
Tough
Very dense
Extremely durale
Corrosive resitant
High melting point
Give some properties of tungsetn
corrosive resiatnt
very dense
Very high tensile strength,
Very strong when made into alloys or compounds
What are some non ferrous metal alloys
Brass
Bronze
Talk about brass
good conductor
Made of copper and zinc
It is bright gold - making it suitable for metal work
It can be easily ast
Low melting point
It is good for jobs where low friction is required
Talk about bronze
Tough
corrosion resitant
can be cast
Give some ways of measuring the mechanical proeprties of ferrous and non ferrous metals
Strength
Hardness
Toughness
elasticity
Plasticity
Brittleness
Ducility
Mallabilility
where woudl aluminium be sued
drinks cans
biek frames
plan bodies
cookign shit
foil
