Alloy 47-6 (Pernifer 4706): Engineering guide to properties and applications

Engineering specifications and standards for Alloy 47-6

Alloy 47-6, also known as Pernifer 4706, is a precision nickel-iron-chromium alloy designed for electrical engineering and instrumentation applications. Its unique physical properties make it indispensable for components requiring stable thermoelectric behavior. EV Group China supplies this material in the form of strips and wires, fully compliant with DIN 17745 and SEW 385 standards.

Component analysis of the precision alloy Alloy 47-6

The precise stoichiometry of components is key to the alloy's performance characteristics. The balance of nickel (47%), iron (46%), and chromium (6%) ensures predictability and stability of magnetic and electrical properties over a wide operating temperature range, which is critical for high-precision instruments.

Mechanical properties of Alloy 47-6 at 20°C

The alloy possesses a balanced complex of mechanical properties: a tensile strength of ~540 MPa is combined with high ductility (elongation at break not less than 35%). This allows for the manufacturing of complex configuration parts using cold plastic deformation methods, such as deep drawing and stamping.

Key physical and thermal constants of Alloy 47-6

The physical constants of the material determine its functional purpose. With a density of 8.20 g/cm³, the alloy is characterized by stable electrical resistivity (85 μOhm·cm at 20°C) and a Curie temperature of about 350°C. These parameters make it ideal for the production of cores and shields operating under conditions of alternating magnetic fields and thermal cycles.
