1. Mtedza wa chitsulo chosapanga dzimbiri-
Mtedza wa chitsulo chosapanga dzimbiri-umapereka mphamvu zolimba kuti zisamachite dzimbiri, kulimba kwambiri, kusamva bwino, komanso kulimba kwambiri. Chifukwa chake, ndizoyenera kugwiritsa ntchito zomwe zimafunikira mphamvu zambiri, kuuma, komanso kukana dzimbiri, monga kugwiritsidwa ntchito m'malo am'madzi ndi nyengo yachinyontho.
2. Copper self-mtedza wothira
Copper self- mtedza wa clinching umapereka mphamvu yabwino kwambiri ya magetsi, kukana corrosion, resistance kuti oxidation, ndi thermal conductivity. Chifukwa chake, ndizoyenera kugwiritsa ntchito zomwe zimafunikira madulidwe amagetsi komanso kukana kwa dzimbiri, monga m'minda yamagetsi ndi zida zamagetsi.
Aluminiyamu mbale self- mtedza wophikira uyenera kupangidwa ndi chitsulo chosapanga dzimbiri kapena mkuwa. Ngati mphamvu zapamwamba ndi kukana dzimbiri zikufunika, chitsulo chosapanga dzimbiri chikulimbikitsidwa; ngati ma conductivity abwino ndi kukana dzimbiri akufuna, mkuwa ndi woyenera kwambiri. Kusankha nokha-zinthu za mtedza wothira kuyenera kutengera momwe mungagwiritsire ntchito komanso zofunikira.
