Metals Flashcards
What is a common property of ferrous metals?
High tensile strength and durability
This property makes ferrous metals suitable for various structural applications.
True or False: Most ferrous metals are magnetic.
True
Magnetism is a key characteristic of ferrous metals due to their iron content.
What protects stainless steel from rust?
The presence of chromium
Chromium forms a protective layer that prevents corrosion.
What are the properties of cast iron?
Hard but brittle, resists deformation and rust
Cast iron is known for its strength and resistance to wear.
List three uses of cast iron.
- Kitchen pans
- Machine bases
- Manhole covers
These applications take advantage of cast iron’s durability.
What is a property of low carbon/mild steel?
Tough and ductile
This type of steel is versatile and used in various applications.
List three uses of low carbon/mild steel.
- Car bodies
- Steel building frames
- Pipelines
These uses highlight the material’s strength and flexibility.
What is a property of high carbon steel?
Hard but brittle
This steel is known for its hardness, which affects its brittleness.
List two uses of high carbon steel.
- Tools
- Blades
High carbon steel is ideal for making items that require a sharp edge.
What is an alloy?
A mixture of metals
Alloys combine properties of different metals to enhance performance.
What is one advantage of alloys?
Can take on specific tasks
Alloys can be tailored for specific applications, improving their functionality.
What are the properties of high speed steel?

What are non-ferrous metals?
A group of pure metals that do not contain iron
Non-ferrous metals have distinct physical and chemical properties.
List two properties of non-ferrous metals.
- Non-magnetic
- Higher resistance to rust
These properties make non-ferrous metals useful in various applications.
What is a common use of aluminium?
Bike frames
Aluminium’s lightweight nature makes it ideal for bicycle manufacturing.
What are the properties of zinc?
Brittle yet malleable, high corrosion resistance
Zinc is often used for protective coatings.
What are two uses of copper?
- Plumbing supplies
- Electrical cables
Copper’s excellent conductivity makes it essential in electrical applications.
What is a property of tin?
Malleable and ductile
These properties allow tin to be easily shaped and formed.
