It is suitable for use at temperatures up to 600°C (1110°F). As a very malleable, very ductile alloy, it has a very good resistance to oxidation. The alloy is non-magnetic. It is suitable for electrical resistors, potentiometers, heating wires, heating cables and mats. Ribbons are used for heating of bimetals. Another field of application is manufacturing of thermocouples because it develops a high electromotive force (EMF) in association with others metals.Manufactured according to international quality. System (ISO9001).Stable resistance and long-life span.High-quality,short delivery and well after-sell service. Alloy Ni% Mn% Fe% Cu% CuNi44 43 Max0.5 __ Balance Density 8.9 Resistivity 0.49 Tensile strenght ≥420 Max.working temperature 400 Melting point 1280 Elongation ≥25
