Features and Application Notes
A-COPPER 11 is used as negative leg for the compensating lead
for thermocouple types Pt10Rh-Pt and Pt13Rh-Pt. A-COPPER 11 is
standardized in the temperature range between 0 and +200 °C.
Form of Delivery
A-COPPER 11 is supplied in the form of wires with dimensions from
0.05 to 13.50 mm Ø in bare condition. Enamelled wires are available
in dimensions between 0.05 and 1.50 mm Ø. A-COPPER 11 can also
be supplied in form of stranded wire, ribbon, at wire and rods.
Please contact us for the range of dimensions.
1) The exact EMF values can be calculated with a “EMF-Software”, which can be downloaded from our homepage.
2) Reference at 0 °C.
3) The mechanical values considerably depend on dimension. The indicated values refer to a dimension of 1.0 mm diameter.
Notes on Treatment // A-COPPER 11 is easy to process.
Copper-nickel alloys can be soft and hard soldered as well as
welded by the known processes. On request we supply material
tested according to DIN EN 60068-2-20.
