Mkuwa ndi mkuwa wangwiro, nthawi zambiri ukhoza kuyerekezedwa ngati mkuwa wangwiro.Ndi bwino madulidwe ndi pulasitiki, koma mphamvu ndi kuuma ndi abwino.
Malinga ndi kapangidwe kake, zida zaku China zopangira mkuwa zitha kugawidwa m'magulu anayi: mkuwa wamba, mkuwa wopanda okosijeni, mkuwa wokhala ndi okosijeni ndi mkuwa wapadera womwe umawonjezera zinthu zingapo zophatikiza (monga mkuwa wa arsenic, mkuwa wa tellurium, mkuwa wasiliva).Mkuwa wa magetsi ndi matenthedwe conductivity ndi yachiwiri kwa siliva, ndipo chimagwiritsidwa ntchito popanga zipangizo zamagetsi ndi thermally conductive.
Ndodo ya mkuwa ndi chinthu chooneka ngati ndodo chopangidwa ndi mkuwa ndi aloyi ya zinki, yomwe imatchedwa mtundu wake wachikasu.Ndodo yamkuwa imakhala ndi zida zabwino zamakina komanso kukana kuvala.Amagwiritsidwa ntchito kwambiri popanga zida zolondola, zida za sitima, zida zamagalimoto, zida zamankhwala, zida zamagetsi ndi mitundu yonse ya zida zothandizira zamakina, mphete zamano zama synchronizer zamagalimoto.
