Metals and Alloys Flashcards
What are the three metal categories?
Ferrous, Non-Ferrous and Alloys
Give three examples of a Ferrous metal:
Iron, Mild Steel and High Speed Steel
What are the properties of Mild Steel?
Twice the price of oil
Tough, Can withstand stress
Can be worked whilst cold
Suitable for machining and welding
What are the properties of High-Carbon Steel?
Less Ductile than Mild Steel
Good Strength and Wear properties
Not Tough, will shatter if excessive stress is applied
What are the properties of Cast Iron?
Rougher texture than Steel
Cheaper to process than Steel
Easy to form shapes from
Machines easily
What are the Advantages of Aluminium?
Lightweight
Easy to cut
Resists corrosion
What are the Disadvantages of Aluminium?
Low Strength
Hard to weld
What are the uses of Aluminium?
Bike Frames
Food Packaging
What are the Advantages of Copper?
Very Ductile
High Heat and Electrical Conductivity
What are the Disadvantages of Copper?
Turns Green when subjected to moisture
Expensive
What are the uses of Copper?
Electrical Wiring
Plumbing pipes
What are the Advantages of Zinc?
Malleable
Resistant to Corrosion
What are the Disadvantages of Zinc?
Unsightly grains
Very weak
Poor Strength
What are the uses of Zinc?
Very simple cast products
Coating metal - Galvanising
Give three Non-Ferrous metals:
Aluminium
Copper
Zinc
