Sharaxaadda Badeecada:

Silig daawaha 4J28, oo sidoo kale loo yaqaanSilig daawaha Fe-Ni, waa walxo birlab iyo galaas ah oo jilicsan oo sax ah. Iyada oo leh halabuurka oo inta badan ka kooban bir iyo qiyaastii 28% nikkel, waxay bixisaa isbarbardhig heer sare ah oo ku saabsan ballaarinta kulaylka oo leh galaaska borosilicate, taasoo ka dhigaysa mid si weyn loogu isticmaalo baakadaha elektaroonigga ah iyo codsiyada shaabadaynta galaaska ilaa birta.

Silig 4J28 ahwaxay muujisaa sifooyin shaabad oo heer sare ah, waxqabad birlab oo deggan, iyo astaamo farsamo oo la isku halleyn karo. Waxaa si ballaaran loogu isticmaalaa tuubooyinka elektaroonigga ah, baakadaha hermetic-ga, guryaha semiconductor-ka, iyo qaybaha hawada sare iyo militariga oo lagu kalsoonaan karo.

Astaamaha:

• Shaabad aad u fiican oo ka kooban galaas ilaa bir: Waafaqsanaanta ballaarinta kulaylka ee ugu habboon ee leh galaaska borosilicate ee shaabad adag oo hermetic ah

• Sifooyinka Magnetic-ga ee Wanaagsan: Ku habboon codsiyada magnetic-ga jilicsan iyo jawaabta magnetic-ga ee deggan

• Saxnaanta Cabbirka Sare: Waxaa laga heli karaa dhexroor aad u fiican, oo si sax ah loogu sawiray qaybaha elektaroonigga ah ee xasaasiga ah

• Iska caabbinta Oxidation-ka: Dusha sare oo dhalaalaya, aan oksaydh lahayn, oo ku habboon faakiyuumka iyo shaabadeynta kalsoonida sare leh

• La habeyn karo: Cabbirrada, baakadaha, iyo xaaladaha dusha sare waxaa loo habeyn karaa baahiyaha macaamiisha gaarka ah

Codsiyada:

• Tuubooyinka elektaroonigga ah iyo aaladaha faakuumka

• Relaysyada iyo dareemayaasha shaabadaysan ee galaas-ilaa-birta ah

• Xirmooyinka Semiconductor iyo Hermetic

• Qalabka elektaroonigga ah ee hawada sare iyo kuwa militariga

• Qaybaha indhaha iyo microwave-ka ee u baahan isbarbardhigga ballaarinta kulaylka saxda ah
