  4. Wadanne kafofin watsa labarai na yau da kullun ake amfani da su wajen tauraruwar induction? Kafofin watsa labarai na gama-gari waɗanda ake amfani da su a cikin tauraruwar ƙara sun haɗa da ruwa, mai, da mafita na polymer. Zaɓin matsakaicin kashewa ya dogara da abubuwa kamar kayan abun, girman, da adadin sanyaya da ake so. Tsarukan kashewa na musamman, kamar matsi mai ƙarfi ko quenching cryogenic, ana iya amfani da su don takamaiman aikace-aikace.
  5. Ta yaya hardening induction ya kwatanta da sauran matakan taurare dangane da tasirin muhalli? Ƙarfafa ƙora gabaɗaya ana ɗaukarsa a matsayin tsari mai dacewa da muhalli saboda ƙarfin kuzarinsa da ƙarancin samar da sharar gida. Idan aka kwatanta da tsarin taurare na tushen tanderu na gargajiya, hardening induction yana cinye ƙarancin kuzari kuma yana haifar da ƙananan hayaki, yana mai da shi zaɓi mai dorewa don ayyukan kula da zafi.
