1. Karma alloy

Ko te koranu Karma he parahi, he nickel, he konumohe me te rino hei waahanga matua. Ko te parenga he 2~3 wa teitei ake i te MENTONG. He iti ake te whakarea pāmahana o te ātete (TCR), te iti o te EMF waiariki ki te parahi, he pai te pumau o te aukati mo te wa roa me te kaha anti-oxidation. Ko tana awhe pāmahana mahi he whanui ake i te MENTONG (-60~300ºC). He pai mo te hanga i nga huānga parenga me te riaka.

2. Rahi Karma

Waea: 0.01mm-10mm
Ripene: 0.05*0.2mm-2.0*6.0mm
Wehe: 0.5*5.0mm-5.0*250mm
3. Nga ahuatanga motuhake o te waea aukati Karma

1) Ka timata me te Nickel Chromium waea wera hiko Class 1, i whakakapihia e matou etahi o te Ni
Al me etahi atu huānga, a na reira i tutuki i te rauemi ātete pū me te pai ake
whakarea pāmahana ātete me te kaha hiko hiko ki te parahi.
Na te taapiri o Al, kua angitu matou ki te hanga i te parenga rōrahi kia 1.2 te rahi ake
atu i te Nickel Chromium waea wera hiko Class 1 me te kaha tensile 1.3 wa nui ake.

2) He iti rawa te whakarea pāmahana tuarua β o te waea Karmalloy KMW, - 0.03 × 10-6/ K2,

a, ko te anau pāmahana parenga ka huri tata ki te raina tika i roto i te whanui
awhe pāmahana.

No reira, kua whakaritea te whakarea pāmahana ki te whakarea pāmahana toharite i waenga
23 ~ 53 °C, engari 1 × 10-6/K, te whakarea pāmahana toharite i waenga i te 0 ~ 100 °C, ka taea hoki
kia tangohia mo te whakarea pāmahana.

3) He iti ano te kaha hiko ki te parahi i waenga i te 1 ~ 100 °C, kei raro + 2 μV/K, me

ka whakaatu i te tino pumau i roto i nga tau maha.

4) Mena ka whakamahia tenei hei rauemi tuuturu, he maimoatanga wera wera iti
e hiahiatia ana ki te whakakore i nga huringa tukatuka pera i te keehi o te waea Manganin CMW.
