When you choose the right materials for a project or product, it is very important to make a reasonable choice, not only to choose this material does not use that material, but more importantly to use the material which performance as a basis.If you don't have a better reference, try the following features.Little gifs, fun and useful.
Strength
The material should be able to withstand the test of force in the application scene, not bending, constantly, not broken, not deformed.
Tremble, feel my weight
Hardness
Harder materials are generally more scratch resistant, durable, and resistant to tear and indentation.
Friction. Friction
Elasticity
The material absorbs force, can bend in different directions and can return to its original state.
Spin, jump, I don't stop
Formability
Is it convenient to process into a permanent shape, although soft persimmon can be knead but finished.Another extreme example is diamonds that are too hard to process.Diamonds can be used for other purposes.

Ductility
The force and deformation capacity in the length direction.The elastic of the rubber band is very good.In materials, thermoplastic elastomers generally have good ductility.
Hey, it's a little sticky
Tensile strength
The ability to deform before breaking or breaking.
Oh, no, no
Malleability
Before cracks appear, the ability of the material to change shape in all directions is tested by the ability of the material to be plastic again.
Hammer it with the left hand and weld it with the right. I believe I can
Toughness
Material impact resistance, a sudden knock, will not break or broken.

Electrical conductivity
Normally, materials with good electrical conductivity also have good thermal conductivity.
