Using a combination of online and paper resources, find out as much as you can about the seven materials listed below.  In particular, consider the QUANTITATIVE values for their properties of:

o  Strength

(the stress that can be withstood before permanent deformation or breakage  occurs)

o  Stiffness

(the strain that results from applied stress)

o  Ductility

(the willingness of a solid material to deform predictably, rather than shatter, under applied stress)

o  Electrical resistivity

(the reluctance of a given area to let electricity flow)

o  Thermal conductivity

(the amount of thermal power needed to create a temperature rise across a   given piece of material)

o  Density

(the mass of a specific volume of the material)
