Entuthukweni ebalulekile,904l imigoqo yensimbi engenasiciKuvele njengokuqukethwe okuthandwayo ezimbonini zokushisa okuphezulu, ukuguqula indlela imikhakha ehlukahlukene ebhekana ngayo nokusingatha ngayo izindawo zokushisa ngokweqile. Ngokuqina kwayo okuvikelekile okuhlukile kanye nokuqina kokugqwala, insimbi engenacala engu-904l isisungule ngokwayo njengendlela yokuya kwizicelo ezibucayi lapho amazinga okushisa aphakeme abe yinselele.
Ukudluliswa kwesikhalazo se-904l yensimbi engenacala ekwakhiweni kwayo okuyingqayizivele nezakhiwo. Le allioy inamathela okuqukethwe okuphakeme kwe-chromium ka-23-28%, okuhambisana nekhabhoni ephansi kanye nokuqukethwe okuphezulu kwe-nickel (19-23%). Lezi zimfanelo zinikela ngekhono lazo elihlaba umxhwele lokugcina ubuqotho bezinhlekelele futhi bamelane ne-opidation ngisho nakwimibandela ebingadala ukonakala kwezinye izinto.
