Simbi yekucheka yemahara inoreva simbi yealloy iyo inowedzera imwe chiyero cheimwe kana kupfuura yakasununguka yekucheka zvinhu senge sulfur, phosphorus, lead, calcium, selenium, tellurium, nezvimwewo kuvandudza machinability yayo.Neyo otomatiki, kukurumidza-kumhanya uye kurongeka kwekucheka, zvakakosha kuti simbi ive yakanaka machinability, iyo inonyanya kushandiswa kugadzira pamichina yekucheka otomatiki.Izvi zvinotevera zvinotarisa mutsauko uripo pakati pe1215 yemahara yekucheka simbi uye 11SMn30 yemahara yekucheka simbi.
1215 imhando yesimbi iri nyore yekucheka muAmerican ASTM/AISIBI standard series.1215 yemahara yekucheka simbi ndeye zvakatipoteredza ine hushamwari zvinhu izvo zvisina lead kana zvinokuvadza zvinhu kune zvakatipoteredza.Iyo ine yakanaka yekucheka zvivakwa uye inokodzera general electroplating shafts, yekucheka zvinhu, uye zvakajairika zvikamu.
