Nickel Chromium Heat Resistance Alloy Electrical Wire 2080/3070
HNickel Chromium kupisa kupikisa alloy yemagetsi waya 2080/3070
Iwo maNickel-Chrome waya anoshandiswa zvakanyanya seyakanyanya kupikisa alloy yekudziya magetsi uye waya-maronda resistors muindasitiri yesimbi, indasitiri yemakemikari uye indasitiri yemagetsi, nezvimwe.
Iyi alloy waya ine yakakwirira yemagetsi kuramba coefficient, yakanaka anti-oxidation uye anti-corrosion performance, uye zvakare ine yakanaka mechanic workability uye weldability, ine simba rakakura pakupisa kwakanyanya.
Hunhu hunokosha hweNi-Cr uye Ni-Cr-Fe magetsi ekudziya alloys
