I-alloy 290/C17200 ucingo lwe-nickel-copper alloy lwe-potentiometers/shunts

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.

Iinkcukacha
Intambo yemanganin/CuMn12Ni2 Intambo esetyenziswa kwiirheostats, iiresistor, iishunt njl.njl. Intambo yemanganin 0.08mm ukuya kwi-10mm 6J13, 6J12, 6J11 6J8
Ucingo lweManganin (i-cupro-ucingo lwe-manganese) ligama elinophawu lwentengiso lwe-alloy edla ngokuba yi-86% yobhedu, i-12% yemanganese, kunye ne-2-5% ye-nickel.
Ucingo lweManganin kunye nefoyile zisetyenziswa ekwenziweni kweresistor, ingakumbi ii-ammeter shunts, ngenxa yokuba azinawo ubushushu obufanelekileyo be-resintent value kunye nozinzo lwexesha elide.

Ukusetyenziswa kweManganin

Ifoyile yeManganin kunye nocingo zisetyenziswa ekwenziweni kweresistor, ingakumbi i-ammeter shunt, ngenxa yokuba ayilingani nobushushu obupheleleyo kunye nozinzo lwexesha elide.
I-alloy yokufudumeza esekwe kubhedu engaphantsi kokumelana isetyenziswa kakhulu kwi-low-voltage circuit breaker, i-thermal overload relay, kunye neminye imveliso yombane ene-low-voltage. Yenye yezinto eziphambili kwiimveliso zombane ezine-low-voltage. Izinto eziveliswa yinkampani yethu zineempawu zokungaguquguquki okuhle kunye nozinzo oluphezulu. Singabonelela ngazo zonke iintlobo zeengcingo ezingqukuva, ezithe tyaba kunye nezixhobo zeshiti.
