Description of Standard Eagle AAA

 

Eagle AAA alloy is a soft magnetic alloy containing approximately 80 % nickel, 4.20 % molybdenum, and 15 % iron which develops extremely high permeabilities with minimum hysteresis loss. The material is provided with the correct temper to permit users to perform a variety of cold forming operations. It can be fabricated into shields by roll forming, spinning, deep drawing, hydroforming and other conventional sheet metal operations. Where joining is required, spot welding or tungsten inert gas welding can be used.

 

Magnetic Properties of Standard Eagle AAA

 

Eagle AAA is capable of displaying a minimum DC permeability of 60,000 at a flux density of 40 gausses when heat treated.

 

Typical DC Permeability Range:

 

 

60 Hz Impedance Permeability (µz) vs. Flux Density

E-I Sine Test Method, ring specimens. Heat treated- H2 2150° F (1177° C) for 4 hrs., cooled at a rate of 600° F (333° C) per hr.
