Le alloy yi-air melted nickel-base alloy, yaphuhliswa nguRolls Royce (1971) Ltd. ukuze ibonelele ngemathiriyeli yeshiti enokuthi yenziwe lula kwaye iya kubonelela ngeductility ephuculweyo kwiindibano ezidityanisiweyo ukuze zithathe indawo ye-NIMONIC ialloy 80A. ukuhlangabezana neekhrayitheriya zoyilo oluthile ngokwemiqathango yobungqina boxinzelelo kunye namandla okurhubuluza.Ngoku ifumaneka kuzo zonke iifom eziqhelekileyo.Ubuchule be-welding yale ngxube ifana nezo zisetyenziswayo kwezinye ii-alloys ze-nickel base-age-hardable.uring salvage imisebenzi welding, i-pre weld heat-treatment ayiyomfuneko kwiindibano zobunzima obudala kodwa unyango olulandelayo lwe-age-hardening luyanqweneleka emva kokuba yonke i-welding salvage igqityiwe.

•I-alloy yamandla aphezulu, ukuqina kwemvula.
•Ukuqulunqwa kwe-alloy kwintsimi yesicelo se-welding kulungile
•I-ductility egqwesileyo.
Nimonic 263 Applications :
Ilungele ukwenziwa kwesakhiwo sentsimbi kunye neenjini zenqwelomoya kunye namacandelo e-injini yegesi.
