Xun Shi New Materials Co Ltd supplies 3J21 alloy for elastic
components, 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.
Density:8.3g/cm3
