Daxalkani si fiican ayuu ugu shaqeeyaa jawi oksaydhaynta ilaa 815°C wuxuuna iska caabiyaa warbaahinta kala duwan ee daxalka.

Roobab adag– Inconel 660 waxaa lagu adkeyn karaa roobka iyadoo la adeegsanayo daaweynta kulaylka gabowga. Wareegga gabowga ee caadiga ah (675-705°C, 12-16 saacadood) wuxuu horumariyaa sifooyin farsamo oo ugu fiican wuxuuna bixiyaa iska caabin nasasho walaac oo aad u fiican, taas oo muhiim u ah codsiyada bolting.

Iska caabinta Daalka Wanaagsan– Daawadu waxay bixisaa iska caabin aad u fiican oo ku wajahan daalka iyo daalka kulaylka, taasoo ka dhigaysa mid ku habboon qaybaha ku xiran rarista wareegga heerkulka sare. Tani waxay si gaar ah muhiim ugu tahay codsiyada marawaxadaha iyo qaybaha matoorka.

Shaqo-karti iyo Machinability Aad u Fiican– Inconel 660 wuxuu leeyahay mashiin ka wanaagsan kuwa kale ee superalloys. Si fudud ayaa loo farsameyn karaa, si kulul ayaa loo shaqayn karaa, qabowna waa loo shaqayn karaa. Daloolada waxaa lagu alxan karaa iyadoo la isticmaalayo TIG, MIG, iyo alxanka iska caabbinta iyadoo la adeegsanayo biraha buuxinta ee ku habboon.
