Isabellenhütte ISOTAN®

Admin — Mon, 23 Nov 2020 20:58:50 +0000

ISOTAN® thermocouple alloy is a versatile Copper-Nickel alloy (CuNi44Mn1), offering a low-temperature coefficient and high resistance to oxidation and chemical corrosion. While it can be used for electrical resistors and potentiometers, it is not suitable for precision components due to its high EMF compared to Copper. ISOTAN® can be supplied in a wide range of grades, qualities and versions depending on the application and customer’s requirements (such as custom standardised temperature range). Most commonly it is used as a negative leg of thermocouple types J, L, T, U or E, extension and compensation leads. ISOTAN® is available in form of round wires from 0.03 to 10mm² which can be bare or enamelled (between 0.05-1.5mm²), flat wire, ribbons or rods.

Please see the datasheet for an outline guide of properties. When submitting an enquiry for ISOTAN®, please provide information about the application and/or any specific requirement for the alloy properties – this allows us to judge the best grade/version of ISOTAN® and offer the best possible price.

Isabellenhütte MANGANIN®

Admin — Mon, 23 Nov 2020 20:57:51 +0000

MANGANIN® resistance alloy is a Copper-Manganese-Nickel alloy (CuMn12Ni) invented by Isabellenhütte in 1889 and perfected over the years to excellent quality and long term stability of electrical resistance. It features a very low-temperature coefficient between +20°C and +50°C with a parabolic shape of the R(T) curve, extremely low EMF (vs. Copper), average specific resistance and good working properties. MANGANIN® is used by Isabellenhütte for their own components, particularly the ISA-WELD and ISA-PLAN resistors. It offers a maximum working temperature in the air of +140°C, with higher thermal loads in a non-oxidising atmosphere available. MANGANIN® is available in form of round wires from 0.02 to 8.00 mm² which can be bare or enamelled to the highest standard, stranded wires, flat wires, ribbons or rods.

As with all Isabellenhütte alloys, all manufacturing from the raw material is done at their German plant with state-of-the-art equipment and under continuous testing to achieve a fully tracked manufacturing process. This allows Isabellenhütte to make slight adjustments in order to melt an alloy tailored to a customer’s requirement. Please see the datasheet in the Technical library, however, do not hesitate to contact us if what you require is not exactly matched.

Resistance alloy CuMn12Ni
Industry-standard material for precision, standard and shunt resistors
Temperature coefficient of electrical resistance of ±10 ppm/°C between +20°C and +50°C
Temperature range of up to +140°C in air
Extremely low thermal EMF compared to Copper
Suitable for soldering, brazing, welding and dip-tinning

Typical applications for MANGANIN® resistance alloy include:

Precision, standard and shunt resistors for a range of industries (note to achieve highest quality component, resistors should be carefully stabilised, aged to relieve mechanical stress and the application temperature should not exceed 60°C)
Low-cost replacement for silver solder for hard metal mounting

Isabellenhütte is one of the world’s leading manufacturers of precision alloys, offering the highest quality on the market. They produce precision resistance and thermocouple alloys for a variety of applications such as the ones listed above for their MANGANIN® alloy.

Isabellenhütte ISAOHM®

Admin — Mon, 23 Nov 2020 20:57:51 +0000

ISAOHM® resistance alloy is a Nickel-Chromium alloy (NiCr20AlSi) offering high resistivity, low-temperature coefficient, low thermal EMF compared to Copper and high tensile strength. It is also resistant to oxidation and chemical corrosion, allowing the working temperature of up to +250°C for precision resistors/current measurement applications (when used for heat generation it can be used for much higher temperatures). ISAOHM® is available in form of round wires from 0.01 to 0.6 mm² which can be bare, oxidised or enamelled to the highest standard, stranded wires and flat wires.
As with all Isabellenhütte alloys, all manufacturing from the raw material is done at their German plant with state-of-the-art equipment and under continuous testing to achieve a fully tracked manufacturing process. This allows Isabellenhütte to make slight adjustments in order to melt an alloy tailored to a customer’s requirement, such as adjusting the resistivity by special heat treatment. Please see the datasheet in the Technical library, however, do not hesitate to contact us if what you require is not exactly matched.

Resistance alloy NiCr20AlSi
Low-temperature coefficient of electrical resistance
Temperature range of up to +250°C when used for current measurement/resistor applications (higher is used for heat generation)
Low thermal EMF compared to Copper
Suitable for brazing, welding and can be soldered under certain conditions

Typical applications for ISAOHM® resistance alloy include:

High-value resistors
Potentiometers
Automotive industry
Consumer electronics
Heating cords and cables
