ʻO Nickel Chromium NiCr Alloy
Hoʻohana nui ʻia nā mea Nickel-chromium i nā umu uila ʻoihana, nā mea hana hale, nā mea mamao-infrared a me nā mea hana ʻē aʻe ma muli o ko lākou ikaika wela kiʻekiʻe a me ka plasticity ikaika. Hiki ke hana ʻia ʻo Nickel-chromium a me ka hao, aluminika, silikoni, kalapona, sulfur a me nā mea ʻē aʻe i ka nickel-chromium alloy wire, nona ka resistivity kiʻekiʻe a me ka pale wela a ʻo ia ka mea hoʻomehana uila o ka umu uila, hao hao, hao uila a nā huahana ʻē aʻe.
Eia kekahi, hoʻohana pinepine ʻia ka uea NiCr i loko o ka coil o ka sliding rheostat e pale i ke kaapuni a hoʻololi i ke ʻano o ke kaapuni ma o ka hoʻololi ʻana i ke kūpaʻa o ka ʻāpana kaapuni komo, a laila hoʻololi i ka volta ma waena o ka conductor (mea uila) i hoʻopili ʻia me ka moʻo. ia, Hoʻohana nui ʻia i ka nui o nā mea hana hale.
NiCr Alloy Series
ʻO Ni90Cr10 strip ke ʻano o nā huahana nickel-chromium alloy, kūpono ia no nā noi wela a hiki i 1250 ° C. Hāʻawi ka ʻike Chromium i ka manawa ola maikaʻi loa, hoʻohana maʻamau ia ma ke ʻano he mea hoʻomehana vape.
Hōʻike ʻia ʻo Ni90Cr10 e ka resistivity kiʻekiʻe, ke kūpaʻa oxidation maikaʻi, ka ductility maikaʻi ma hope o ka hoʻohana ʻana a me ka weldability maikaʻi loa. ʻO NiCr Alloy kahi mea maikaʻi no ka ʻoihana hoʻomehana.
