In the electrotechnical industry only electrolytic copper (electrolytically refined) having a purityof 99.60-99.90% is used. Characteristics specific to electrolytic copper:
- density, = 8.9 kg /C
- electrical conductivity, = 58 (at 20 C )
- electrical resistivity,= 0,01724 (at 20 C )
- thermal conductivity = 0,938.
Can send samples if interested.
