Where to find material properties data for metals and non-metals

[Skyeagle]

Hi,

Anyone can recommend any website that shows the material properties (such as reflectivity, heat capacity, density, heat conductivity) of both non metals and metals?

Thanks in advance.

Some properties for many materials can be found at MatWeb.com

reflectivity is rather special and one might need a special resource, such as a supplier, for that.
