Copel - copper-nickel alloy containing 43% Ni and 0,5% Mn, else Cu. In chemical composition, physical and mechanical properties similar to Konstantan, Kopel melting point of about 1290 ° C. Of all copper-nickel alloys Kopel has a maximum thermoelectric power in conjunction with Chromel (about 6.95 mV at 100 °C, 49.0 mV at 600 °C). Mainly used as a negative pyrometry thermoelectrodes thermocouple measured temperatures up to 600 °C, as compensating cable as well.
Density of the alloy - 8900 kg/m3, the melting point of 1220-1290 ° C, the temperature coefficient of linear expansion of 14.10 -6 ° C-1, the electrical resistivity of 0.5 mO · m It has a high thermoelectric power paired with many metals and is used for the manufacture of electrodes thermocouples.
