Ferrosilicon ni umusemburo w'ingenzi ukoreshwa mu gukora ibyuma n'ibindi byuma. Igizwe nicyuma na silikoni, hamwe nibindi bintu bitandukanye nka manganese na karubone. Uburyo bwo gukora ferrosilicon burimo kugabanya quartz (dioxyde de silicon) hamwe na kokiya (karubone) imbere yicyuma. Iyi nzira isaba ubushyuhe bwinshi kandi ikoresha ingufu nyinshi, bigatuma ibiciro byibikoresho fatizo bigira uruhare runini muguhitamo igiciro rusange cya ferrosilicon.

Nitride ya Ferrosilicon na nitride ya silicon yumvikana nkibicuruzwa bibiri bisa cyane, ariko mubyukuri, biratandukanye cyane. Iyi ngingo izasobanura itandukaniro riri hagati yibi bitandukanye.

Ferromolybdenum ni ferroalloy igizwe nicyuma na molybdenum. Ihingurwa no gushonga imvange ya molybdenum hamwe na fer yibanze mu itanura. Ferromolybdenum nuruvange rwinshi rushobora gukoreshwa mubikorwa bitandukanye mubikorwa bitandukanye.

Amavuta ya Tungsten-fer asanzwe yerekeza ku mavuta agizwe na tungsten (W) n'icyuma (Fe). Muri rusange, tungsten-fer alloys ntabwo ari magnetique.Ibi ni ukubera ko tungsten ubwayo ari icyuma kitari magnetique, kandi ibyuma biri muri tungsten-fer bivanze mubisanzwe ni bike, bidashobora guha amavuta magnetisme ikomeye.

Titanium ntabwo ari magnetique.Ibi ni ukubera ko titanium ifite imiterere ya kirisiti idafite electroni zidakorewe, zikenewe kugirango ibikoresho bigaragaze magnetism. Ibi bivuze ko titanium idakorana na magnetique kandi ifatwa nkibikoresho bya diamagnetic.
