NiCr 80/20matenthedwe kupopera wayandi zinthu zapamwamba kwambiri zopangira kupopera mbewu kwa arc. Wayayu amapangidwa ndi 80% nickel ndi 20% chromium, zomwe zimapangitsa kukhala chisankho chabwino kwambiri popanga zokutira zomwe zimafunikira kukana kutentha kwambiri, kukana dzimbiri, komanso kukana kwa okosijeni. NiCr 80/20 imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza zakuthambo, kupanga magetsi, petrochemical, ndi kupanga, kuteteza ndi kubwezeretsanso malo, kukulitsa kukana kuvala, ndikukulitsa moyo wazinthu zofunikira kwambiri. Kuchita kwake kwapamwamba m'malo ovuta kumapangitsa kukhala yankho lodalirika lazofuna zambiri.
Kukonzekera koyenera pamwamba ndikofunikira kuti mupeze zotsatira zabwino ndi NiCr 80/20matenthedwe kupopera waya. Pamwamba pake payenera kutsukidwa bwino kuti muchotse zonyansa monga mafuta, mafuta, dothi, ndi ma oxides. Kuphulika kwa grit ndi aluminium oxide kapena silicon carbide tikulimbikitsidwa kuti tikwaniritse roughness ya 50-75 microns. Kuonetsetsa kuti pamakhala poyera komanso movutikira kumawonjezera kumamatira kwa zokutira zopopera zotentha, zomwe zimapangitsa kuti ntchitoyo ikhale yabwino komanso moyo wautali.

Waya wa NiCr 80/20 wopopera wotentha amapereka njira yolimba komanso yothandiza popititsa patsogolo mawonekedwe azinthu zomwe zimawonekera kwambiri. Mawonekedwe ake apadera amakina komanso kukana kutsekemera kwa okosijeni ndi kuvala kumapangitsa kuti ikhale yamtengo wapatali pamafakitale osiyanasiyana. Pogwiritsa ntchito waya wopopera mafuta wa NiCr 80/20, mafakitale amatha kusintha kwambiri magwiridwe antchito ndi moyo wautumiki wa zida ndi zida zawo.
