**This Powerpoint specifically uses the Cambridge iGCSE Chemistry Syllabus and covers all criteria for – Unit 9.3 Alloys and their properties
**

Students will be able to -

CORE
1 Describe an alloy as a mixture of a metal with
other elements, including:
(a) brass as a mixture of copper and zinc
(b) stainless steel as a mixture of iron and other
elements such as chromium, nickel and
carbon

2 State that alloys can be harder and stronger
than the pure metals and are more useful

3 Describe the uses of alloys in terms of their
physical properties, including stainless steel in
cutlery because of its hardness and resistance
to rusting

4 Identify representations of alloys from diagrams
of structure

Supplement

5 Explain in terms of structure how alloys can
be harder and stronger than the pure metals
because the different sized atoms in alloys
mean the layers can no longer slide over each
other

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a FREE pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
