1. Hordhac maaddo
Silverwaa curiye kiimiko ah oo sumad lehAgiyo nambarka atomiga 47. Bir jilicsan, cad, dhalaalaysa birta kala guurka ah, waxa ay muujisaa korantada ugu saraysa, socodka kulaylka, iyo milicsiga birta kasta. Birta waxa laga helaa qolofka dhulka ee saafiga ah, qaabka aasaasiga ah ee bilaashka ah ("slver hooyo"), sida daawaha leh dahab iyo biraha kale, iyo macdanta sida argentite iyo chlorargyrite. Lacagta inteeda badan waxaa loo soo saaraa wax soo saar ka samaysan naxaasta, dahabka, rasaasta, iyo sifaynta zinc.
Silver ayaa muddo dheer lagu qiimeeyay birta qaaliga ah.

2. Sharaxaada dahaarka
Siliga magnetka ee dahaaran ee Polyimide wuxuu awoodaa inuu shaqeeyo ilaa 250 °C. Daboolida silig labajibbaaran oo dhumuc weyn ama leydi leh ayaa inta badan lagu kordhiyaa iyadoo lagu duuduubo heerkul sare oo polyimide ah ama cajalad fiberglass ah, iyo dabaysha la dhamaystiray ayaa inta badan faakuum lagu dhex daraa varnish dahamiya si loo hagaajiyo xoogga dahaarka iyo kalsoonida muddada dheer ee dabaysha.
Gariiradaha iskood isu taageera ayaa lagu dhaawacay silig lagu dahaadhay ugu yaraan laba lakab, kan ugu dambeeyana waa heerkulbeeg isku xidha wareegyada marka la kululeeyo.
Noocyada kale ee dahaarka sida fiberglass dun ah oo leh varnish, warqad aramid, kraft papaer, mica, iyopolyesterFilimka ayaa sidoo kale si weyn loogu isticmaalaa adduunka oo dhan codsiyada kala duwan sida transformers iyo reactors. Qeybta maqalka, silig ah dhismo qalin ah, iyo dahaadhyo kale oo kala duwan, sida suufka (mararka qaarkood waxaa lagu dhex dahaadhay nooc ka mid ah wakiilka xinjirowga/dhoobo, sida beeswax) iyo polytetrafluoroethylene (PTFE) ayaa laga heli karaa. Alaabta dahaadhka qadiimka ah waxaa ka mid ah suuf, warqad, ama xariir, laakiin kuwani waxay kaliya faa'iido u leeyihiin codsiyada heerkulka hooseeya (ilaa 105 ° C).
Si loo fududeeyo wax soo saarka, qaar ka mid ah siligga magnet heerkul hooseeya ayaa leh dahaar laga saari karo kulaylka alxanka. Tani waxay ka dhigan tahay in isku xirka korantada ee cidhifyada la samayn karo iyada oo aan marka hore la saarin dahaarka.
