What are the twelve key properties of materials?

  1. Strength
  2. Elasticity
  3. Plasticity
  4. Ductility
  5. Tensile Strength
  6. Malleability
  7. Toughness
  8. Hardness
  9. Conductivity
  10. Durability
  11. Compressive Strength
  12. Torsional Strength

2

What is meant by the strength of a material?

Strength is the ability of a material to stand up to forces being applied without it bending, breaking, shattering or deforming in any way

3

What is meant by the elasticity of a material?

Elasticity is the ability of a material to absorb force and flex in different directions, returning to its original position.

4

What is meant by the plasticity of materials?

Plasticity is the ability of a material to be change in shape permanently. For instance aluminium can be melted and poured into a mould. When it has cooled it's shape will retain the mould's shape.

5

What is meant by the ductility of materials?

Ductility is the ability of a material to change shape (deform) usually by stretching along its length. Lead is a metal that can be deformed in this way.
 

6

What is meant by the tensile strength of a material?

Tensile strength is the ability of a material to stretch without breaking or snapping.

7

What is meant by the malleability of a material?

Malleability is the ability of a material to be reshaped in all directions without cracking. By heating a piece of steel until it is red hot, it becomes malleable and can be reshaped with a forging hammer.

8

What is meant by the toughness of a material?

Toughness is the characteristic of a material that does not break or shatter when receiving a blow, impact or under a sudden shock. The opposite of toughness is brittleness.

9

What is meant by the hardness of a material?

Hardness is the ability of a material to resist scratching, wear and tear and indentation

10

What is meant by the conductivity of a material?

Conductivity is the ability of a material to conduct electricity and heat.

11

What is meant by the durability of a material?

Durability is the ability to withstand wear and tear. Rubber is a very tough and durable material. We can put it under extreme stress by clamping it into a vice. When we open the vice we find the rubber returns to its original shape and is unmarked.

12

What is meant by the compressive strength of a material?

Compressive strength is the ability of a material to withstand being crushed.

13

What is meant by the torsional strength of a material?

Torsional strength is the ability to withstand twisting.
