The properties of the metal

The metals are chemical elements that are obtained from metallic minerals and are solid to temperature ambience (except the mercury). This type of material has a big importance in the industry, since it is very useful. 

The properties of the metal: 

Thickness: There is a big thickness difference according to the type of metal. The high thickness of a lot of metals it stems from the crystalline layer that has the metallic structure. 

Conductivity: The value of the thermal and electrical conductivity is usually very high. 

Melting point: It is the temperature in which an element goes on from the solid state to liquid. The tin is the metal with the lowest melting point (232°C). 

Determination: In general, the metals are resistant to the impacts and blows. 

Elasticity: The metals do not recover the initial form as soon as an effort was done. 

Hardness: The hardness changes very much according to the type of metal. There is of soft like the lead and five-peseta coins like the tungsté.
