1. Starter 1– Metals and alloys test
Match up the metal with the correct properties and examples
A Low carbon steel –
B High carbon/tool steel
C Stainless steel-
1.) Hard – Cutting tools
2.) Easily shaped – Car body panels
3.) Resistant to erosion – Cutlery and Sinks A B c

2. Answers – Question 1 type of steel iron alloyed with properties
typical use
low carbon steel
about 0.25 per cent carbon
easily shaped
car body panels
high carbon steel
up to 2.5 per cent carbon
hard
cutting tools
stainless steel
chromium and nickel
resistant to corrosion
cutlery and sinks A 2 B 1 C 3

3. Starter 2 –Non Ferrous metals do not contain ironB A
Match up the metal with the correct properties and examples • A) Aluminium • B) Copper • C) Tin • D) Zinc
1.) Resistant to corrosion, fairly hard, good conductor of heat and electricity. Examples: Ornaments, cast items such as water taps
2.) Good strength-to-weight ratio, light, soft, ductile, good conductor of heat and electricity - Examples: Kitchen equipment, window frames, general cast components
3.) Soft, weak, malleable, ductile and resistant to corrosion. Examples: Usually used for coating steel to form tin-plate, soft solder.
4.) Malleable and ductile, good conductor of heat and electricity, resistant to corrosion. Examples: Water pipes, electrical wire, decorative goods C D

4. Answer – Question 2
ZINC
A Aluminium 2
B Copper 4
C Zinc 1
D Tin 3

5. Starter 3 - Ferrous Metals – Contain iron
A.) Cast Iron
B.) Stainless
C.) Mild Steel
D.) Carbon
1.) Hard skin, softer underneath, but brittle, corrodes by rusting. Example: Parts with complex shapes which can be made by casting.
2.) Hard and tough, resistant to wear and corrosion. Example: Cutlery, kitchen equipment
3.) Even harder than medium carbon steel and more brittle, can be heat-treated to make it harder and tougher. Example: Cutting tools, ball bearings
4.) Tough, Ductile, Malleable, poor resistance to corrosion. Example: General purpose engineering material B C D A
