Cupronickel CuNi44 mhangura-nickel alloy resistance wire ine yepakati-yakaderera resistivity
Iyi yemhangura-nickel resistance alloy, inozivikanwawo sekuti constantan, inoratidzwa nekupokana kwemagetsi kwakabatana nekadikidiki tembiricha coefficient yekupikisa.Iyi alloy inoratidzawo yakakwira tensile simba uye kuramba kune corrosion.Inogona kushandiswa pakupisa kusvika ku600 ° C mumhepo.
CuNi44 imhangura-nickel alloy (CuNi alloy) inepakati-pasi resistivitykuti ishandiswe patembiricha inosvika 400°C (750°F).
CuNi44 inowanzo shandiswa pakushandisa senge tambo dzekudziya, fuse, shunts, resistors uye akasiyana marudzi evatongi.
