Magnetica proprietas ferri grisei fusi late variatur, ab humilitatis permeabilitate et alta vi coactiva ad altam permeabilitatem et vim coactivam humilis.Hae mutationes maxime dependent a microstructura ferrea cinerea iacta.Additis elementis immixtis ad obtinendas proprietates magneticae requisitas obtinetur mutando structuram ferri cineris fusi.

Ferritas altam permeabilitatem magneticam et humilem hysteresim amittit;Margarita est contrarium, humilis magneticam permeabilitatem habet et magnam hysteresim amittit.Pearlite in ferrite formatur per curationem furnum caloris, qui magneticam permeabilitatem quater augere potest.Grana ferrite dilatare potest reducere damnum hysteresis.Praesentia cementitici magneticam fluxum densitatis, permeabilitatis et remanentiae reducet, dum permeabilitas et hysteresis damnum auget.Praesentia crassa graphite remanentiam reducet.Mutatio ab A-typo graphite (lacuta graphite formata sine directione uniformiter distributa) ad D-typum graphitum (graphi subtiliter crispatum cum distributione non-directionali inter dendrites) magneticam inductionem et vim coactivam signanter augere potest. .

Antequam ad criticam caliditatem non magneticam perveniat, siccus ortus insigniter auget magneticam permeabilitatem ferri cinerei missi.Punctum Curie ferrei puri est α-γ temperatura transitus 770°C.Cum massa recipis siliconis sit 5%, punctum Curiae 730°C perveniet.Punctum Curie temperamentum cementi sine siliconibus est 205-220°C.

Matrix structura graduum ferri grisei communiter adhibiti praecipue est margarita, et eorum maxima permeabilitas inter 309-400 μH/m est.
