Menene bambanci?

Haɗuwa

Copper da zinariya abubuwa ne na ƙarfe daban-daban tare da kaddarorin daban-daban.Ƙarfin wutar lantarki na gwal shine 318W / mK, yayin da ƙarfin wutar lantarki na jan ƙarfe ya ɗan fi girma a 401W / mK.Ƙarfin wutar lantarki na jan ƙarfe ya ɗan fi girma a 5.96 x107 S / m fiye da zinariya wanda shine 4.11 × 107 S / m.

Tsawon rayuwa

Mafi mahimmanci shine tsawon rayuwar karafa biyu.Copper yana da babban matakin oxygenation.Don haka, idan an shigar da shi a cikin yanayi mara kyau (kamar waje), zai yi kasawa da wuri fiye da zinariya.Ana iya gyara wannan amma yana buƙatar cire na'urar LED da maye gurbin diode.Idan an shigar dashi a cikin kwanciyar hankali, tsawon rayuwar nunin ya kusan zama iri ɗaya.
