Nikkel iyo nikkel Alloy alxanka Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Sharaxaad: Ni202 waa Ni70Cu30 Monel alloy electrode leh titanium calcium daahan.Waxa loo isticmaali karaa labada AC iyo DC.Birta la shubo waxay leedahay iska caabin dildilaac ah oo wanaagsan sababtoo ah maadada ku habboon ee manganese iyo niobium.Waxay leedahay wax qabad alxanka oo heersare ah oo leh gubasho qallafsan oo deggen, spatter yar, sifudud alxanka, iyo alxanka quruxda badan.
Codsiga: Waxaa loo isticmaalaa alxanka ee nikkel-naxaas daawaha iyo birta la mid ah, iyo sidoo kale waxaa loo isticmaali karaa sida wax ku meel gaar ah.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % |
| La damaanad qaaday | ≥480 | ≥200 | ≥27 |
Hadda lagu taliyay:
| Dhexroor usheeda (mm) | 2.5 | 3.2 | 4.0 |
| Hadda alxanka (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Ogaysiis:
1. Electrode waa in lagu dubaa 1 saac agagaarka 250 ℃ ka hor alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
