Pernifer 36
Alloy 36


Material Characteristics

The iron-based alloy with 36 % nickel has a very low coefficient of thermal expansion of up to 250 °C. In addition, the material Invar 36® has a high toughness and ductility. The low thermal expansion leads to a wide range of application possibilities, for example in the field of measuring instruments or in the optoelectronic industry. Thereby, the additive manufacturing technology enables added values through functional integration.

  1. The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
