Nickel Chromium Alloy 40 Resistance Ribbon Ni40cr20 Uea Pumehana Uila
ʻO Nickel Chromium Resistance Alloy Resistohm 40 Resistance Ribbon Ni40cr20 uila wela uila
Ni40Cr20he austenitic nickel-chromium alloy (NiCr alloy) no ka hoʻohana ʻana i nā mahana a hiki i 1100°C (2010°F). Hōʻike ʻia ka alloy e ka resistivity kiʻekiʻe a me ke kūpaʻa oxidation maikaʻi. He ductility maikaʻi ma hope o ka hoʻohana ʻana a me ka weldability maikaʻi loa.
Nā noi maʻamau noNi40Cr20ʻO nā mea hoʻomehana mālama pō, nā mea hoʻoheheʻe convection, nā rheostats kaumaha a me nā mea hoʻomehana pā. Hoʻohana pū ʻia ka alloy no ka hoʻomehana ʻana i nā kaula a me nā mea hoʻoheheʻe kaula i ka defrosting a me ka de-icing element, nā pākeke uila a me nā pads, nā noho kaʻa, nā mea wela baseboard a me nā mea hoʻomehana papahele, nā mea pale.
