1. Solids: Metals, alloys, Ceramics, Plastics, Composites

2. Liquids: Metals(mercury, Gallium), Inorganics, Organics

3. Gases: Air, Hydrogen, carbon dioxide and a host of others

Any handbook like Perry’s Chemical Engineering Handbook, Lange’s Handbook of Chemistry and others will give a lot of data. Data is also available from sites like

One can draw up a composite table showing all values of electrical and thermal conductivities.

Relative Conductivity

Temperature Coefficient of Resistance

Tensile Strength

I hope these links give you some usefull info:
