Noocyo kala duwan oo naxaas sare ah & Alloys-ka ka kooban nikkel oo leh iska caabin gaar ah oo sarreeya ama hooseeya ayaa caan ku ah isku-dhafka heerkulka hooseeya ee iska caabbinta. Haysashada iska caabbinta sare ee oksaydhka iyo daxalka kiimikaad, Alloys-yadan waxa loo isticmaalaa iska caabiyeyaasha saxda ah ee xadhig-boogaha, potentiometers, qalabka xakamaynta mugga, dabaysha culus ee rheostats warshadaha iyo iska caabbinta korantada. Noocyo kala duwan ayaa loo isticmaalaa kululaynta fiilooyinka leh heerkulka kirishbooyada iyo sida tuubada alxanka "qalabka alxanka korontada".Copper manganese daawahawaxaa loo isticmaalaa walxaha caadiga ah ee saxda ah, caadiga ah iyo iska caabinta shunt.
