Usually, this list contains:  Alloy steel  Aluminum  Brass  Copper  Plastic  Wood  The material properties are fairly accurate and are good for determining center of mass, overall weight, and estimating stresses and deflections.  These material properties can be imported with the geometry into an FEA package and can be used for analysis purposes.

Thus, virtually any metal, polymer, or wood can be created based on actual material properties.  Materials can also be defined entirely from scratch, where the user inputs every parameter by hand.
