Use picture to understand the strength, hardness, elasticity, toughness and ductility of materials!

Strength

The material shall be able to withstand the test of force in the application scene without bending, continuous, breaking and deformation

Hardness

Harder materials are generally more scratch resistant, durable, and resistant to tearing and indentation.

Elastic

The ability of material to absorb stress, bend in different directions and return to its original state.

Formability

Whether it is convenient to process into a permanent shape. Although the persimmon is soft, it can be pinched at will, but it will be finished after pinching. Another extreme example is that diamonds are too hard to be processed. Diamonds can be used to process other.

Ductility

Force and deformation capacity in the length direction. The rubber band has good elasticity. In terms of materials, thermoplastic elastomers generally have good ductility.

Tensile strength

The deformation capacity before or without fracture.

Ductility

The ability of a material to change its shape in all directions before cracks appear tests the ability of the material to plastic again.

Toughness

The impact resistance of the material will not break or break if it is knocked suddenly.

Conductivity

This doesn't need to be said by Xiaobian. Under normal circumstances, materials with good conductivity also have good thermal conductivity.
