Metals and alloys

Question 1

Metallurgy

Answer 1

The study of metals

Question 2

Ferrous

Answer 2

Ferrous metals are metals that contain iron so most are magnetic which is useful in recycling but they are prone to corrosion due to their carbon

Question 3

Carbon content

Answer 3

The more carbon the less malleable the metal is

Question 4

Cast iron

Answer 4

Hard surface, soft core, strong under compression and cheap- used in vices, breaks, discs and manhole covers

Question 5

Low carbon steel

Answer 5

Tensile, tough, malleable, prone to corrosion- used in car bodies, screws, nuts + bolts

Question 6

High carbon steel

Answer 6

Hard, brittle, less malleable/ductile- used in screwdrivers, chisels, taps and drives

Question 7

Non-ferrous

Answer 7

Metals that don’t contain iron, because they are not magnetic they are widely used in electronic devices and wiring

Question 8

Aluminium

Answer 8

Lightweight, soft, ductile, malleable, conductive- used in aircraft bodies, cans, pans and bike frames

Question 9

Copper

Answer 9

Extremely ductile and malleable, very conductive, easily soldered, corrosion resistant- used in wire, plumbing fittings and hot water tanks

Question 10

Zinc

Answer 10

Weak in pure state, resistant to corrosion, low melting point- used in galvanised coating and corrugated roofing

Question 11

Tin

Answer 11

Soft, ductile, malleable, low melting point- used in coating drink cans and solder

Question 12

Alloys

Answer 12

Alloys are made by combining two or more elements and they can be categorised into ferrous and non ferrous based on their metals

Question 13

Brass

Answer 13

Non ferrous- strong, ductile, casts well, conductor- used in castings, forgings and taps

Question 14

Stainless steel

Answer 14

Ferrous- hard, tough, corrosion resistant- used in sinks, cutlery and surgical equipment

Question 15

Duralumin

Answer 15

Non ferrous- strong, soft, malleable, lightweight- used in aircraft structures and fuel tanks
