Ancorsteel phosphorus alloys are ferrous base<br />
powders for P/M parts requiring superior<br />
electromagnetic performance. Compared with<br />
parts made from pure, high compressibility iron<br />
powders, those made from the phosphorus alloys<br />
have higher resistivity, permeability and<br />
induction, and reduced coercive force. The<br />
presence of phosphorus also decreases the<br />
susceptibility of a P/M component to nitrogen<br />
aging. Ancorsteel phosphorus alloys are produced<br />
by making ferrophosphorus additions to the highly<br />
compressible iron powders Ancorsteel 1000B or<br />
Ancorsteel 1000C.<br />

<strong>Phosphorus</strong> <strong>Alloys</strong><br />
Components made from the phosphorus alloys<br />
exhibit a good combination of tensile strength,<br />
ductility, and impact absorption energy. The<br />
particle size of the added ferrophosphorus is<br />
important as it has a significant effect on these<br />
properties. The ferrophosphorus powder should<br />
be finer than 20 micrometers and preferably<br />
should have a median particle size close to<br />
10 micrometers.<br />
The Hoeganaes Corporation products<br />
Ancorsteel 45P and Ancorsteel 80P contain<br />
0.45 and 0.80 weight % (w/o) phosphorus<br />
respectively.<br />
Typical applications for parts made from<br />
Ancorsteel phosphorus alloys include speed<br />
sensors, magnetic solenoids and plungers.<br />
