Uea Alloy Nickel Chromium NiCr
0.03mm Uea NiCr Alloy, 637 MPA Nickel Chromium Pumehana Uea, Ni90Cr10 NiCr Alloy
ʻO Ni90Cr10 kahi austenitic nickel-chromium alloy kūpono no nā noi wela a hiki i 1250 ° C. ʻO ka maʻiʻo chromium kiʻekiʻe (30% i ka awelika) hāʻawi i ka manawa ola maikaʻi loa, ʻoi aku hoʻi i nā noi umu, hoʻohana nui ʻia i ka vape, ma ke ʻano he mea hoʻomehana.
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. ʻAʻole pili ka Alloy i ka "'ōmaʻomaʻo'ōmaʻomaʻo" a ua kūpono loa ia no ka hoʻohaʻahaʻa a me ka hoʻoheheʻe ʻana i nā ea.
Hoʻohana ʻia ʻo Ni70Cr30 no nā mea hoʻomehana uila i nā umu ahi. ʻO nā noi maʻamau: nā umu uila a me nā enamelling, nā mea wela mālama, nā kapuahi a me nā kiln me kahi ea hoʻololi.
Noi o NiCr Alloy Uea:
Loaʻa i nā mea Nickel-chromium ka ikaika wela kiʻekiʻe a me ka plasticity ikaika.
Hoʻohana nui ʻia i loko o nā umu uila ʻenehana, nā mea hana hale, nā ʻenehana mamao-infrared.
Hiki ke hana ʻia ka nickel-chromium a me ka hao, aluminika, silika, kalapona, sulfur a me nā mea ʻē aʻe i ka uwea nickel-chromium alloy me ka pale kiʻekiʻe a me ka pale wela. ʻO ia ka mea hoʻomehana uila o ka umu uila, hao hao, hao uila, etc.
ʻO nā pono o ka uea Nickel-Chromium:
ʻOi aku ka kiʻekiʻe o ke kūpaʻa, ʻoi aku ka maikaʻi o ka pale ʻana o ka ʻili, a ʻoi aku ka maikaʻi o ka compressive ikaika ma mua o ka uea hao-chromium-aluminum ma lalo o ke kiʻekiʻe wela o ke kaiapuni kūlohelohe, a ʻaʻole maʻalahi ka hana ʻana i ka deformation. ʻO ka uea nickel-chromium maikaʻi ka deformation plastic, maikaʻi loa ka hana ʻana a me ka forge-hiki, maʻalahi e hana a hana, maʻalahi e hoʻoponopono a paʻakikī hoʻi e hoʻololi i ke ʻano. Eia hou, nickel-chromium uea i kiʻekiʻe emissivity, maikaʻi corrosion kū'ē a me ka lōʻihi noi manawa.
