ʻO Cr30Ni70 Nichrome Alloy Eletrothermal Coil Strip, Sable Resistance no ka mea wela,
NiCr70/30
Nickel chromium alloy me ka hao pale electrothermal resistivity kiʻekiʻe, kino kino kino maikai. I ka wela kiʻekiʻe a me ka ikaika kiʻekiʻe,
a me ka hana maikaʻi a me ka hana ʻana, hiki ke wiliwili i ke ʻano i hoʻohana nui ʻia me ka metallurgical, uila, ʻāpana mechanical a me ka uila
ʻoihana hana no ka hana ʻana i nā mea pale wela.
ʻAno NiCr: Cr20Ni80, Cr15Ni60, Cr20Ni35, Cr20Ni30, Cr25Ni20 etc.Series uila palahalaha kāʻei, uila ahi uila.
