Njengamanye ama-alloys amaninzi, i-alloys yobhedu kunye ne-copper-based alloys inokubunjwa ibe ngamacandelo anzima kakhulu, ezenza zibe zilungele inkqubo yokutshala imali. Ukuguquguquka rhoqo kweendleko kunokwenza ezi mathiriyeli zibe nexabiso kakhulu, zenze inkcitho ibe yindleko enkulu, ngakumbi xa kuqwalaselwaCNC machiningkunye/okanye ukwenza njengenkqubo yokuvelisa ukuvelisa inxalenye yakho yemveliso. Ubhedu olucocekileyo aluqhelekanga ukuphoswa.
