Excellent properties

High resistivity (specific resistance)

LEONI Histral® R53 is an ideal material for heating elements.

Low temperature coefficient

This shows the relative change of resistance as the temperature rises or falls. Almost all metals have a positive temperature coefficient, meaning that as the temperature increases so does the resistance. This is of particular significance in heating cables and elements. The lower the temperature coefficient of a heating cable, the more uniform the heating power as temperature increases.

The temperature coefficient of LEONI Histral® R53 is 0.00072.

Special applications

  • Heating cables
