Izincomo

Uma usebenzisa endaweni enomswakama, sincoma izinto ze-NiCr 80 (grade A) ozikhethela zona.
Zakhiwe yi-80% ye-Nickel kanye ne-20% ye-Chrome (ayinayo insimbi).
Lokhu kuzovumela izinga lokushisa lokusebenza eliphezulu elingu-2,100o F (1,150o C) kanye nokufakwa lapho ukujiya kungase kube khona emgudwini womoya.

Izinto zekhoyili evulekile ziwuhlobo olusebenza kahle kakhulu lwento yokushisa kagesi kanti futhi zisebenza kahle kakhulu ekusetshenzisweni okuningi kokushisa. Ezisetshenziswa kakhulu embonini yokushisa yemibhobho, izinto zekhoyili evulekile zinezisekethe ezivulekile ezifudumeza umoya ngqo kusuka kumakhoyili aqinile aqinile. Lezi zinto zokushisa zezimboni zinezikhathi zokushisa ezisheshayo ezithuthukisa ukusebenza kahle futhi zenzelwe ukugcinwa okuphansi kanye nezingxenye ezishibhe kalula.
