Description of key information

A number of articles in the public domain, published papers and Safety Data Sheets record the melting point of tin as 231.9°C (equivalent to 505K).  One published paper records the melting point value as 520 K but there is no reason to think this is the correct value considering the weight of evidence that 505 K is correct

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
505 K

Additional information

The melting point of metallic tin is 231.9 °C (505 K)
