I-alloy yokumelana nokuchaneka kwe-MANGANIN iphawuleka ngokukodwa yi-coefficient ephantsi yobushushu phakathi kwama-20 nama-50 °C enesimo se-parabolic se-R(T) curve, uzinzo oluphezulu lokumelana nombane ixesha elide, i-EMF ephantsi kakhulu yobushushu xa ithelekiswa ne-copper kunye neempawu ezilungileyo zokusebenza.
Nangona kunjalo, imithwalo ephezulu yobushushu kwindawo engena-oxidizing inokwenzeka. Xa isetyenziselwa ii-resistors ezichanekileyo ezineemfuno eziphezulu, ii-resistors kufuneka zizinziswe ngononophelo kwaye ubushushu bokusetyenziswa akufuneki budlule kwi-60°C. Ukudlula ubushushu obuphezulu bokusebenza emoyeni kunokubangela ukushukuma kokumelana okubangelwa ziinkqubo ze-oxidizing. Ke ngoko, uzinzo lwexesha elide lunokuchaphazeleka kakubi. Ngenxa yoko, ukuxhathisa kunye ne-coefficient yobushushu bokumelana kombane kunokutshintsha kancinci. Ikwasetyenziswa njengezinto zokutshintsha ezingabizi kakhulu kwi-solder yesilivere yokufakelwa kwesinyithi esiqinileyo.
