Material strength, hardness, elasticity, toughness, ductility
When you choose the right material for a project or product, reasonable choices are very important. Not only is this material not used, but more importantly, what properties are used as a basis. If you don't have a better reference, you may wish to qualify with the following characteristics.
strength
The material must be able to withstand the stress of the application scene, not bent, constant, not broken, not deformed.
hardness
Harder materials are generally more scratch resistant, durable, and resistant to tears and dents.
elasticity
The material absorbs the force, can bend in different directions, and can return to its original state.
Formability
Whether it is convenient to process into a permanent shape. Although the persimmon is soft and can be pinched, it is finished. On the other extreme, diamonds are too hard and are not suitable for processing. Diamonds can be used to process others.
Ductility
Force deformation ability in the length direction. The elasticity of the rubber band is very good. In terms of materials, thermoplastic elastomers generally have good ductility.
tensile strength
The ability to deform before breaking or breaking.
Ductility
Before cracks occur, the material's ability to change shape in all directions tests the ability of the material to plasticize again.
toughness
The material is resistant to impact, and it will not break or break if it is hit suddenly.
Electrical conductivity
Under normal circumstances, materials with good electrical conductivity also perform well.
