1. Lesson objective – to understand the stock forms for metals

2. Name me as many metals and alloys that you can!
Starter -
Name me as many metals and alloys that you can!

3. Every question you answer will get a point for your team and a chocolate bar at the end of the lesson Alloys and alloying
Pure metals have a limited range of properties. By combining two or more metals to produce an alloy, it is possible to produce a material that has a better range of properties and characteristics. This then allows the metals to be used for a range of specific tasks.

4. Remember discussing metals is also science
It's no surprise that if I take a particular metal and 'add' atoms of a second metal that has a lower melting point that the T- melt of the combination is usually lower than that of the pure metal.
Brass is 65%
copper
and 35% zinc

5. How can metals be bought?
Metals can be bought in sheet forms
Are usually sold in imperial sizes (what does this mean?)
But like timber in metric thickness
Many sections such as

6. Task 1 – examination style question complete the material groups the first I have done for you

What is/are alloy metals?
What type of temperatures can they be melted at?
Name me an alloy?
What does the T-melt mean?
What type of stock form shapes do metals come in?
What type of measurements are metals sold in?
What type of thickness measurements?
Why is it a good idea to combine two metals?
What are your marks for the team?
