Metal & Alloy Properties Flashcards
To learn the different uses of metals and alloys
1
Q
What are the properties of low-carbon steel (ferrous metal)?
A
- Malleable and reasonably tough
- Cannot be hardened and tempered
- Inexpensive but rusts easily
2
Q
What are the properties of high-carbon steel (ferrous metal)?
A
- Very hard but brittle
- Difficult to cut and work
- Can be hardened and tempered
- Prone to rust
3
Q
What are the properties of cast iron (ferrous metal)?
A
- Hard but brittle so cannot be bent or forged
- Resistant to deformation, wear and rust
- Strong under compression but not under tension
4
Q
What are the properties of aluminium (non-ferrous metal)?
A
- Durable, lightweight and resistant to corrosion
* A good conductor of heat and electricity
5
Q
What are the properties of copper (non-ferrous metal)?
A
- Relatively soft, malleable and ductile
* A great conductor of heat and electricity
6
Q
What are the properties of tin (non-ferrous metal)?
A
- Soft, malleable and ductile
- High resistance to corrosion
- Has a low melting point
7
Q
What are the properties of zinc (non-ferrous metal)?
A
- Weak but malleable once heated
- High resistance to corrosion
- Has a low melting point
8
Q
What are the properties of brass (alloy)?
A
- Copper and zinc
- Combined to increase hardness
- A good conductor of electricity
- Resistant to corrosion
9
Q
What are the properties of stainless steel (alloy)?
A
- Iron, carbon and a minimum of 10.5% chromium
- Tough, hard, strong and difficult to cut
- High resistance to corrosion if chromium and nickel are added
10
Q
What are the properties of high-speed steel (alloy)?
A
- Various elements such as carbon, tungsten and chromium
- Strong and remains hard even when heated
- Can cut at high speeds and high temperatures
