Metalic materials

Metalic materials

1. Ferrics

   • steel
     • Very good mechanical resistance, especially to traction.
     • Easy to weld.
     • Moderate price.
     • Tools.
     • Kitchen tools.
     • Chairs and tables.
   • Foundry
     • Not malleable and not ductile.
     • Not possible to weld.
     • Cheaper than steel.
     • Engines
     • stands
     • pistons
   • sweet iron
     • - Good magnetic properties
     • Soft, fragile and difficult to machine.
     • Difficult and expensive to obtain.
     • Rarely used.
     • Used in electronics and electrical components.

2. Non ferrous

   • heavy
     • ≥ 5 kg/dm3
       • Example: Lead (Pb), Copper (Cu), Zinc (Zn), Tin (Sn), Nickel (Ni)
   • ultralight
     • ≤ 2 kg/dm3
       • Examples: Magnesium (Mg), Beryllium (Be)
   • light
     • entre 2 y 5 kg/dm3
       • Examples: Alluminium (Al), Titanium (Ti)
     • light
   • Pure non - ferrous metals are generally soft with a low mechanical resistance. In most applications they are used mixed with other elements, we use them in alloys.
   • Non - ferrous metal alloys examples are Bronze and Brass. Bronze is the alloy of tin and copper. Brass is made of zinc and copper.
