Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: No GLP but other quality assurance
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- no
- Remarks:
- Other quality assutance
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- ca. 1 059 °C
- Decomposition:
- ambiguous
- Remarks:
- decrease in mass observed
- Decomp. temp.:
- > 1 071 °C
- Remarks on result:
- other: mass increase, indicative of oxidation starts at 200°C
- Conclusions:
- The report is key to the characterisation of copper
- Executive summary:
During the melting test, the copper powder sample was heated in Al2O3crucible using nitrogen atmosphere. The TG/DSC curves of the tests demonstrated an endothermic peak in the curve is at the temperature ranges 1059 – 1069 °C. This peak indicates melting. The mass of the sample starts to decrease at the temperature 1170 °C.
