In a previous post I mentioned some non-solder uses for low melting point alloys – meaning that they are used for purposes other than simply “joining two surfaces with a filler metal”. There is a second category of materials which do not mechanically join two surfaces – although they do provide electrical and thermal coupling. I’m talking about metal that is liquid at room temperature!
- As a static thermal interface material for electronics components (ex. CPU processor cooling).
- As a dynamic thermal interface material for heat exchangers (ex. nuclear reactors).
- As a thermometer material
- As a captive electrical conductor
- In mirror fabrication
I’m always interested in new liquid metal applications. If you have one in mind, let me know!
