6j22 solution state, mechanical properties of the alloy at room temperature:

Alloy statetensile strengthσb (Mpa)ElongationA5 %
6J22≥690≥18

This alloy has the following properties:

80ni-20cr is mainly composed of nickel, chromium, aluminum and iron. The resistivity is about three times higher than that of manganin, and it has a lower temperature coefficient of resistance and a lower thermal potential for copper. It has a good long-term stability of resistance and oxidation resistance, and a wide use temperature

Metallographic structure of 6j22:

6j22 alloy is single-phase austenite structure

The application fields of 6j22 include:

1. It is suitable for making precise resistance elements in various measuring instruments and meters

2. Suitable for making precise micro resistance elements and strain gauges
