A precipitation hardenable Nickel-Iron-Chromium
alloy having an outstanding controllable thermoelastic coefficient
characteristics and excellent strength and oxidation resistance
in high temperature atmospheres. The alloy can be processed
to have a constant modulus of elasticity at temperatures -45°C
to +65°C. Applications include springs in precise applications,
such as watches and weighing machines.
For minimum hysterisis & low
thermo-elastic coefficient
Stress equalise : 400
oC – 2 Hrs – A/C
(Very high precision
applications will require each batch to be pilot tested, to
determine the specific heat treatment necessary to produce
the required thermo-elastic
coefficient).
