Without proper magnetic annealing, a magnetic shield operates at approximately
15 % efficiency. As supplied by material manufacturer, nickel-iron alloys have
received only a softening anneal intended for general forming purposes. During standard fabrication
which include shearing, punching,
forming, and welding, the material is work hardened which further reduces the
material's magnetic properties.
Eagle Magnetic has developed a Magnetic Annealing
Heat Treat cycle that optimizes shielding properties.
Unless a special cycle is required by the customer, Eagle's standard cycle
has proven to be a cost-effective choice.
Eagle Magnetic can provide special cycles to meet your Heat Treat
specifications.
