Kopel
Copel.
Copel is a copper-Nickel alloy, whose main components are copper (about 55-57 %), Nickel (43-44 %), manganese (0,5 %), additives: iron (2-3 percent), silicon, carbon, sulfur, and other elements in small quantities.
Alloys
Description:
Copel is a copper-Nickel alloy, whose main components are copper (Cu) (base of about 55-57 %), Nickel (Ni) (43-44 %), manganese (Mn) (0,5 %), additives: iron (Fe) (2-3 %), silicon (Si), carbon (C), sulfur (S), and other elements in small quantities.
Used for the manufacture of thermoelectrodes thermocouples of various types, as well as compensation wire to them.
Properties:
– density glory 8 900 kg/m3,
– melting point 1220-1290 °C,
– temperature linear expansion coefficient of 14·10-6 °C−1,
– the specific electric resistance is 0.5 μω·m,
– has a high thermoelectric power paired with many metals.
