| A | B |
| Brittleness | The property of breaking without much perminent distortion. |
| Ductility | When a material can be drawn out in tention without rupture. |
| Elasticity | The power of metal returning to its original shape after deformation by force. |
| Elongation | The ability of stetching without returning to its origonal length. |
| Hardness | The ability to with-stand scratching, wear and abrasion, indentation by harder bodies. |
| Malleability | The property of permanently extending in all directions, without rupture by pressing, hammering, rolling etc. |
| Plasticity | Similar to malleability, exactly the opposite to elasticity, involves permanent deformation without rupture. |
| Strength | The ability to resist the application of force without rupture. |
| Toughness | The ammount of energy a material can absorb before it fractures. |
