Different types of materials and their working properties. (metals)

Question 1

What are Ferrous metals?

Answer 1

Ferrous metals contain iron and are magnetic. They are prone to rust, except for stainless steel and wrought iron.

Question 2

What are non-Ferous metals?

Answer 2

Non-ferrous metals do not contain iron and are not magnetic. They do not rust.

Question 3

What types of metal are Mild steel, stainless steel, and cast iron?

Answer 3

ferrous metal

Question 4

What types of metal are aluminum, copper, and brass?

Answer 4

non-ferrous metal

Question 5

What does ductile mean?

Answer 5

A ductile metal can be bent or stretched easily.

Question 6

What are the properties and common uses of Mild steel?

Answer 6

tough, ductile, malleable, high tensile strength, easily joined. poor corrosion resistants

used for:screws, nails, bolts, girders

Question 7

What are the properties and common uses of Stainless steel?

Answer 7

corrosion resistant, hard, tough, sometimes magnetic, resists wear, difficult to cut

used for: kitchenware, sinks, cutlery, medical equipment

Question 8

What are the properties and common uses of Cast iron?

Answer 8

Hard skin, brittle, softcore, good in compression, self-lubricating, magnetic

used for:Machine parts, vices, brake disc, manhole covers

Question 9

What are the properties and common uses of aluminum?

Answer 9

corrosion resistant, malleable, ductile, easily machined, polishes well

used for: aircraft, foil, window frames, engine parts, drink cans

Question 10
