High Elastic Alloy 3j1 Strip for Elastic Elements
3J1 precision alloy is an iron-nickel-chromium austenite
precipitation strengthening type with high elasticity alloy. After
solution treatment, it has good plasticity, low hardness and easy
processing and forming. After aging treatment after solid solution
or cold strain, high mechanical properties and elastic properties
are obtained.
This type of alloy has the characteristics of high strength, high
elastic modulus, small elastic aftereffect and hysteresis, weak
magnetic properties, good corrosion resistance and thermal
stability, and can be used at higher temperature and greater
stress. Or work under corrosive media conditions. 3J1 alloy can
work below 250℃. This type of alloy can also be used at low
temperatures (such as near -200°C).
For 3J1(Ni36CrTiAl),the equivalent in other country is
ЭИ702,36HXTЮ, A286
Product features:
High elasticity, corrosion resistance, weak magnetic or
non-magnetic.
Application:
It is mainly used to make Make precision sensors, mechanical filter
vibrators, tuning forks of frequency resonators, and reeds and
diaphragms in resonant relays.
