Metals

Question 1

Ferrous metal definition and properties

Answer 1

contain iron, have a high tensile strength, most are magnetic, vulnerable to rust if exposed to moisture - except stainless steel

Question 2

Examples of ferrous metals

Answer 2

low carbon steel, high carbon steel, cast iron

Question 3

Properties and uses of low carbon steel

Answer 3

tough and durable, rusts easily, car bodies, steel buildings, frames, pipelines

Question 4

Properties and uses of high carbon steel

Answer 4

hard but brittle, hard wearing, resists abrasion, retains its shape, tools, blades, scissors

Question 5

Properties and uses of cast iron

Answer 5

hard but brittle, resists deformation and rust, kitchen pans, machine bases, manhole covers

Question 6

Non-ferrous metal definition and properties

Answer 6

pure metals that do not contain iron, non magnetic so can be used for wiring, higher resistance to rust but can corrode

Question 7

Properties and uses of zinc

Answer 7

brittle, malleable, high corrosion resistance, used to galvanise steel

Question 8

Properties and uses of copper

Answer 8

ductile, malleable, good electrical conductor, plumbing supplies, electrical cables

Question 9

Properties and uses of tin

Answer 9

malleable, ductile, high corrosion resistance, good electrical conductor, solder, plating surfaces such as cans

Question 10

Properties and uses of aluminium

Answer 10

lightweight, ductile, resists corrosion, bike frames, drink cans, takeaway trays
