Nīkeli Chromium Alloy Ni80cr20 Pāpā Wela Wela
Nikela Chromium AlloyUea Paa Ni80cr20 Mea Wela
ʻO Ni80Cr20 kahi nickel-chromium alloy (NiCr alloy) Hiki iā ia ke hana i nā uhi paʻa paʻa maikaʻi me ka mīkini maikaʻi maikaʻi, conductivity uila a me ke kūpaʻa o ka wela wela a hiki i 1800 degere F (980 degere C), a paʻa i ke ola lawelawe ʻoi aku ka maikaʻi ma mua o ka hao. chromium alumium alloys. Hōʻike ia i ka wela exothermic i ka wā hoʻohana
Noi:
ʻO nā noi maʻamau no Ni80Cr20 he uilamea hoʻomehanas i nā mea hana hale, nā kapuahi ʻoihana a me nā mea pale (nā mea pale uea, nā mea pale kiʻi metala), nā hao pālahalaha, nā mīkini hao, nā mea hoʻomehana wai, nā mea hoʻoheheʻe plastik, nā hao hao, nā mea tubular metala a me nā mea pahu pahu.
