2 Uses
2.1 Uses & Benefits
- Its alloys with copper or nickel are used in manufacturing Gyroscopes, springs, electrical contact and non sparking tools.
- Beryllium Alloys are used as a material for aircraft, missiles, spacecraft and satellite.
- Thallium is a toxic metal and hence it has limited uses. Thallium metal is mostly used for producing photoelectric cells.
- In thermometer’s mercury alloy has 8% of thallium, as it has a melting point lower than 20°C.
