Standard Specification for 50 Nickel-50 Iron Powder Metallurgy Soft Magnetic Parts
STANDARD published on 1.6.2020
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers the magnetic property requirements of 50 nickel-50 iron soft magnetic parts fabricated by powder metallurgy techniques in the sintered or annealed conditions, intended for parts that require high magnetic permeability, high electrical resistivity, low coercive field strength, and low hysteresis loss. Magnetic parts shall be tested and adhere to chemical composition and sintered density requirements, to which magnetic and residual induction strongly depends on. Parts shall also be tested for their conformance to coercive field strength requirements. The user and producer shall agree upon a representative number of specimens for testing.
