Kurapa kwekupisa kwemariveti nekunze kwekukiya core kunogona kukamurwa kuita nzira ina: kudzima lead, normalizing, spheroidal annealing uye kurapwa kwe solid solution. Mushure mekupisa, kudhirowa kunopfuura kamwe chete kunodiwa, uye mamiriro ekutumira ndeekudhirowa kwakareruka kana kutonhora. Kuburikidza nenzira dzakasiyana dzekupisa uye kudzora huwandu hwekumanikidzwa kwekunze kwekukiya core kudhonza riveti, kuti isangane nezvinodiwa zvehunyanzvi zvezvigadzirwa zvakasiyana.
