Asalkii hore
Ganacsi ahaan saafi ah amanikkel alloy hooseWaxay ka heshaa codsigeeda ugu weyn ee farsamaynta kiimikada iyo elektiroonigga.
Iska caabinta daxalka
Sababtoo ah caabbinta daxalka ee nikkel saafiga ah, gaar ahaan kiimikooyinka kala duwan ee yareeya iyo gaar ahaan alkaliska caustic, nikkel waxa loo isticmaalaa in lagu ilaaliyo tayada wax soo saarka falcelin kiimikaad badan, gaar ahaan habaynta cuntooyinka iyo soosaarka fiber-ka synthetic.
Guryaha Nikkel Ganacsi ahaan Saafi ah
Marka la barbardhigoalwaaxyada nikkel, Nikkel ganacsi ahaan saafi ah ayaa leh koronto-koronto oo sarreeya, heerkul sare oo Curie ah iyo sifooyin magnetostrictive wanaagsan. Nikel waxa loo isticmaalaa fiilooyin elektaroonik ah oo rasaasta rasaasta ah, qaybaha baytariyada, thyratrons iyo electrodes-ka iftiimaya.
Nickel waxa kale oo uu leeyahay kulaylka wanaagsan. Tani waxay ka dhigan tahay in loo isticmaali karo kuleyliyeyaasha kuleyliyaha meelaha daxalka leh.

Farsamaynta nikelka
La xiraynikkelwuxuu leeyahay qallafsanaan hooseeya iyo ductility wanaagsan. Nickel, sida dahabka, qalinka iyo naxaasta, waxa uu leeyahay shaqo adag oo aad u hoosaysa, tusaale ahaan uma eka in uu noqdo mid adag oo jajaban marka uu qalloocan yahay ama si kale u qalloocsan yahay sida inta badan biraha kale. Sifooyinkan, oo ay weheliyaan alxanka wanaagsan, ayaa ka dhigaya birta si fudud in loo sameeyo walxo dhammaatay.
Nickel oo ku jira Plating Chromium
Nickel waxa kale oo inta badan loo isticmaalaa sida jaakad hoose oo lagu qurxiyo chromium. Alaabada ceeriin, sida naxaasta ama shubista zinc ama garaacida birta birta ah ayaa marka hore lagu dahaadhay lakabnikkeldhumucdiisu qiyaastii 20µm. Tani waxay siinaysaa caabbinta daxalka. Jaakada kama dambaysta ah waa 'flash' (1-2µm) chromium ah oo dhuuban si ay u siiso midab iyo caabbinta wasakhaysan taas oo guud ahaan loo arko inay tahay mid aad loogu jecel yahay alaabta dahaadhka ah. Chromium kaligiis ayaa lahaan lahaa iska caabin daxalka ah oo aan la aqbali karin sababtoo ah guud ahaan dabeecadda dalool ee chromium electroplate.
