Which of the following is not a brittle material?

Question 1

Which of the following is not a brittle material?
1. Copper
2. Cast iron
3. Concrete
4. Glass

Question 2

Correct Answer - Option 1 : Copper

Explanation:

Brittleness

Brittleness is the opposite of ductility.
Brittle materials show little deformation before fracture and failure occurs suddenly without any warning i.e. it is the property of breaking without much permanent distortion.
Normally if the elongation is less than 5% the material is brittle. E.g. cast iron, glass, ceramics are typical brittle materials.
Brittle materials have the following characteristics:
- High compressive strength [compressive strength > tensile strength]
- Low tensile strength
- Very low impact and impact strength and toughness

Copper is a ductile material.
