AD-MU-Alloys
1. MIL N 14411
C
and ASTM A753-02 certified.
2. AD-MU Alloys
protect permanently.
3. AD-MU alloys will not saturate when properly used.
4. No excessive loss of permeability from shock.
5. Relatively stable permeability characteristics are
exhibited
after final anneal avoiding the expense and inconvenience of
regularly repeated annealing.
6. Minimal retentivity is displayed by AD-MU alloy for any
alloy of
a given permeability.
All
AD-MU
Material is compliant with EU-RoHS Directive 2002/95/EC and certified full compliance with DFARS clause
252.255-7014 (Alt).
