Are there any other plastic products besides stretch?
The metal bond in different degrees, while the ductility was also different. The nature of metal minerals, such as gold, silver, natural natural natural copper has good ductility. When using a knife scratching the malleable mineral, mineral surface is carved in the light immediately left grooves, without powder or granules. It can be distinguished from brittle.
When the external force (hammer or rolling) function can crush into sheets without rupture is called ductility. Such as ductility of metal, including gold, platinum, copper, silver, tungsten and aluminum are rich in ductility. Quartz, glass and other non-metallic materials have some ductility at high temperature. Ductility is a property of metal minerals, one under external force characteristics of metal mineral is key to produce plastic deformation, which means that the mobile ions can rearrange and lose cohesion, which is the root cause of metal bond minerals with ductility.
Ductility refers to the degree of temper used. Forging material without annealing can be malleable material. Temper rolling, annealing and rolling to temper. Brittle material in the temper rolling after the degree of L is poor. The object under the action of external force can be extended into filaments and properties called ductility fracture;
