Since Isabellenhütte invented Manganin® resistance alloy in 1889, the company name has been synonymous to quality and top-of-the-range precision alloys on the market. Over the years they were able to make and perfect other resistance alloys such as Zeranin®, Isaohm® and Noventin®. Their common denominator is an excellent long term stability, achieved by good corrosion resistance and permanent microstructure of homogeneous mixed crystals. Closely toleranced conductivity, low thermal stress and very low temperature coefficient mean these products are not just resistance alloys - they are precision resistance alloys.
Isaohm® 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 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.

Isotan® is a versatile Copper-Nickel alloy (CuNi44Mn1), 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 wide range of grades, qualities and versions depending on the application and customer's requirements (such as custom standardised temperature range). The 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 in the Technical library for 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.

Manganin® 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 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.
