The units withstand 500 kg / m2. according to studies carried out by laboratories certified by the DF government.
This metal has a combination of properties that make it very useful in mechanical engineering, such as its low density (2,700 kg / m3) and its high resistance to corrosion.

Suitable alloys can significantly increase its mechanical strength (up to 690 MPa). It is a good conductor of electricity and heat, easily mechanized and relatively inexpensive. For all this, it became the most used metal after steel, since the middle of the XX century.
