material qualities

ive seen a page that had this before but cant seem to find it now,
does anyone know of a page which describes the basic material properties of plastic, marble, metal etc.
thanks

I know the red book has a list referenced in the color plates.

excellant thanks for the link, certainly a lot more places after the decimal point than what ive been using. then again thats an old trick of mine (gives the impression that youve researched it thoroughly)
