Metalic Materials

Metalic Materials

1. Contain iron (Fe)

   • Ferrous
     • Pure iron
       • Properties
         • Properties: It has good magnetic properties, it is soft and fragile. It is difficult to make and it rusts really easily. It is really expensive and difficult to obtain
       • Applications
         • It is rarely used. Its main uses are electronics and electronical components
     • Steel
       • Properties
         • It has a strong mechanical resistance, especially traction. It is tough, malleable ductile and easy to weld. It is not very resistant to corrosion and it alloys with chrome and nickel to make stainless steel. It has a moderate price
       • Applications
         • It has a lot of applications. It's used for structures in constructions and vehicles. It's also used for tools, especialy kitchen tools, and for chairs and tables
     • Cast iron
       • Properties
         • It's not malleable nor ductile and it isn't possible to weld. It's brittle and it doesn't have much mechanical resistance, but it's cheaper than steel
       • Applications
         • Applications: It's used for elements with difficult shapes, engines, stands for machines, pistons and steel tramps
