Sharaxaada Alaabta
Xadhkaha iska caabbinta ee la dahaadhay ayaa si balaadhan loogu isticmaalay iska caabiyeyaasha caadiga ah, baabuurta
Qaybaha, iska caabiyeyaasha dabaysha, iwm. iyadoo la adeegsanayo habka dahaarka ee ugu habboon codsiyadan, iyadoo si buuxda looga faa'iidaysanayo sifooyinka gaarka ah ee dahaadhka dhaldhalaalka.
Intaa waxa dheer, waxaanu samayn doonaa dahaarka dhaldhalaalka ee siligga birta ah ee qaaliga ah sida qalinka iyo siliga platinum marka la dalbado. Fadlan ka faa'iidayso wax-soo-saarkan-dalbashada.
Nooca siliga Alloy qaawan
Daawaha aan samayn karno ee la dahaadhay waa Copper-nickel alloy silig, silig Constantan, silig Manganin. Kama Wire, NiCr Alloy silig, FeCrAl Alloy silig iwm silig daawaha
