Haina Nichrome Waea Whakawera Ni80cr20 mo te Hanga Matapihi Fuse me te Wheketere

Waea Whakawera Nichrome Ni80cr20 mo te Matapihi Fuse

Whakaahuatanga Poto:

Kei a Cr20Ni80 nga waahanga matawhānui pai. Ko nga huānga whakawera-kounga teitei ka whiriwhiri i te Cr20Ni80. Ko te Cr20Ni80 nga painga o te pai o te kaha o te hauora, te kaha nui, te kore-aukume, te teitei o te kaha, te pai o te waikura, te kore o te ngohengohe, te kore o te rereke, me te iti o te elongation pumau.Nickel-chromium, nickel, ferrochrome waea whakarewa me te hiko teitei o te wera o te wera o te waikura, te kaha nui, kaore i te ngohengohe me te raupapa o nga painga. I te wa e whakamahia ana i roto i te wa roa, he iti rawa te momo me te elongation pumau, he nui ake te Cr10Ni90 koranu me nga waahanga matawhānui tino pai, ko te whakaputa i nga momo momo kounga teitei mo nga waahanga hiko.
