| Environmental remarks | Tungsten is mainly mined from underground resources. Main producing countries are China with 48% and CIS with 21%. The remaining sites are distributed al over the world. The average metal content is 0.6%. In the US 20-30% is recycled. Tungsten has a resource index of 143 year. | |
General
| Remarks | Strongest metal with the highest melting temperature of all metals. High hardness and corrosion resistance. At elevated temperatures the metal must be protected against oxidation by air. Pure tungsten can be forced, drawn and extruded. The thermal expansion is almost the same as for glass. | |

Last november was a memorable month for us at Matbase, we passed the milestone of 1000 visitors per day. So I guess we were not that far of when we thought it would be a good idea to make the material database we used as students during our stay at the Delft University of Technology accessable to other people. Apparently, people appreciate the easy way they can lookup the material properties and how we present the data.
