Metal properties and processes
Lesson details
Learning outcome
I can identify and justify the material and process used for a metal product.
Key learning points
- There are two main stages in the sourcing of metal: mining and extracting.
- There is an environmental impact to extracting and processing metals.
- Stainless steel does not corrode when exposed to liquids.
- Die casting is a suitable manufacturing process for complex metal shapes.
Keywords
Extracting - remove or take out
Ore - rock containing metal
Electrolysis - electricity is passed through a substance which causes a chemical change
Die casting - a method of shaping metal, molten metal is forced into a mould under pressure
Common misconception
Recycling metals reduces their quality.
Most metals, including aluminium and steel, can be repeatedly recycled without negatively impacting their properties.
Teacher tip
Give pupils the opportunity to handle a variety of metal products. Interacting with the products will enrich the learning. A demonstration of casting would be useful.
Equipment
Product examples made using the process of die casting.
