Alloy 294/Cuprothal/Constantan Copper Nickel 40 Wire / Flat Waya yekupisa
Constantan Strip (CuNi44Mn) Copper Nickel Magetsi Resistance Heating Ribhoni
Constantan Wire Tsanangudzo
Resistance alloy ine mwero resistivity uye yakaderera tembiricha coefficent yekupikisa ine flat kuramba/tembiricha curve pamusoro pehupamhi hwakakura kupfuura "manganins". CuNi44 Alloy wire inoratidzawo zvirinani kusagadzika kwecorrosion kupfuura murume anins. Mashandisirwo anowanzo kuve akaganhurirwa kune ac maseketi. CuNi44/ CuNi40 /CuNi45 Constantan Copper Nickel Alloy Wire zvakare chinhu chisina kunaka chemhando J thermocouple ine Iron iri iyo yakanaka; Type J thermocouples inoshandiswa mukupisa kurapa maapplication. Zvakare, ndicho chinhu chisina kunaka cherudzi rweT thermocouple ine OFHC Mhangura iyo yakanaka; mhando T thermocouples anoshandiswa pane cryogenic tembiricha.
