Hi
I do not think COMSOL has made that simple, as the value of all those material data is high, it would be too simple "just" to copy them all off.
Material data is one of the essential keys for correct model results, and even in the collection of COMSOL Material data base, the values are not all 100% because over time people get better and better in measuring these parameters, and i.e. a steel comes in many formulas, and tempers and each has slightly different material parameters.
You get a lot of material data by searching on the Web with Google or other indexers, you will notice that mostly you get quite some spread in values, for even the "same" material. You have also sites like NIST.gov, and Matweb.com and may other, some free others paying.
The most important is that you can easily import and adapt a material data into COMSOL, either from their material database, or from others, and you can build up your private database with values you have checked and that you trust 100%, just be aware its stored, by default in the your user .../.comsol/... subdirectory so when you upgrade, you need to move it, before you delete all those old files ;)

Good luck

Also, Matweb supports the COMSOL material data format so you can export their material datasheets and read directly into COMSOL Multiphysics without modifications.
