High-precision alloy provides 90µΩcm resistivity

Noventin offers the benefits of resistivity with a low temperature dependence (±20ppm/K in the temperature range from +20 to +50°C), high long-term stability and a low EMF against copper of ±0.3µV/K. Due to the frequent use of copper as a contact material, the latter benefit plays an important role in avoiding fault current caused by temperature differences. Noventin can be used in a wide range of applications, such as in the making of wire-wound resistors and heating resistors or as hard-soldering or construction material. 

Copper-manganese alloys have been used for years in a variety of applications on account of their good technological features, such as low melting points, good malleability, mechanical stability and corrosion resistance. Isabellenhütte developed the Manganin alloy, which is also based on copper and manganese, in the late 19th century. To this day, it remains the state of the art for high-precision resistance alloys.

Isabellenhütte will unveil this innovation at Wire 2014, the global trade fair for the wire and cable industry, in Dusseldorf, 7-11 April. Find out more about using the material at booth 11B33 in hall 11.
