Magnedur 20-4
MagneDur 20-4 is a cobalt-free alloy with semihard magnetic properties. It is malleable and ductile, lending itself to the manufacture of strip, foil, and wire. It is primarily used in the industrial and consumer industries with its key properties including:
- Cobalt-free
- Semi-hard magnetic properties
- Malleable and ductile

Protection You Can Count On
The strength of MagneDur 20-4 depends on the processing. Yield strength can range from 100 to 225 kpsi (689 to 1550 MPa) and ultimate strength from 180 to 250 kpsi (1240 to 1723 MPa). The alloy is reasonably tough and workable in all conditions. MagneDur 20-4 has been used in theft detection tags. This alloy could also be considered for applications in instruments and hysteresis motors.
