Detailed below are fourteen questions about metals, divided into two tables. Table A

is a list of metals and you are asked to decide which are ferrous or non-ferrous.

Table B contains questions that require a true or false answer.

Table A Non-Ferrous or Ferrous

1 Mild Steel Non-Ferrous Ferrous

2 Brass Non-Ferrous Ferrous

3 Carbon Steel Non-Ferrous Ferrous

4 Aluminium Non-Ferrous Ferrous

5 Cast Iron Non-Ferrous Ferrous

6 Stainless Steel Non-Ferrous Ferrous

7 Silver Non-Ferrous Ferrous

8 Wrought Iron Non-Ferrous Ferrous

Table B True or False

9 Stainless Steel is an alloy of iron, nickel and

chromium. True False

10 Brass is an alloy of copper and zinc. True False

11

Copper is resistant to corrosion but it changes

colour from the usual reddish orange to reddish

brown

True False

12 Aluminium is toxic and this property makes it

not suitable as a cooking material True False

13 Cast iron is an alloy of iron and carbon True False

14 Silver is a very good conductor of electricity True False
