Working characteristics of materials Flashcards
1
Q
Conductivity
A
A material’s ability to transmit heat or electricity.
2
Q
Relative hardness
A
This compares the hardness of one material to another. There are standardized hardness tests, but a simple test is scratch resistance. A harder material can scratch a softer one.
3
Q
Density
A
The mass of a material per unit volume.
4
Q
Toughness
A
A material’s ability to absorb energy before breaking.
5
Q
Ductility
A
A material’s ability to be stretched into thin wires without breaking.
6
Q
Tensile Strength
A
The maximum stress a material can withstand before pulling apart.
7
Q
Compressive Strength
A
The maximum stress a material can withstand before crushing
8
Q
Malleability
A
A material’s ability to be hammered or pressed into thin sheets without breaking.
