Product Description

3J21 Superelastic Alloy Wire Diameter 0.10-6.0mm Shock Resistance


3J21 is a deformation reinforced cobalt-based alloy, with good plastic properties and easy to process in the solid solution state. After high strain rate cold processing and time limit treatment, 3J21 can obtain high mechanical and elastic properties, but after the solid solution treatment, the alloy can no longer be strengthened by time limit treatment.

The 3J21 alloy strip materials we supplied have been successfully exported to a seal manufacturer in Italy, replaced the elastic materials previously produced in France.



High strength

High hardness

High elasticity limit

High energy storage ratio

High fatigue strength

Small elasticity lag and rear effect

Non magnetic

Good wear resistance

Shock resistance

Excellent Corrosion Resistance


Working at high and low temperature condition, high temperature up to 400 °C


3J21 is mainly used for elastic element for aviation required wear resistance, corrosion resistance, seismic, no magnetic, thin wire, strip, spring, and film elements below 400℃, but also for making special bearings with highcorrosion resistance and non magnetic, and 3j21 also used for making small shaft, ball, stamping mold and blade tools.
