Jure yanayin zafi har zuwa 1800 ℃ ba tare da laushi ko nakasawa ba
Yi tsayayya da narkakkar karfe da zaizayar kasa, yana tsawaita rayuwar sabis na tanderun da kashi 30%+.
Rage mitar kulawa da farashin samarwa ga abokan ciniki .
Muna ba da mafita na musamman bisa ga nau'in tanderun ku, girman ku, da yanayin aiki. Tuntube mu a yau don ƙarin koyo game da tsarin samar da bulo na magnesium carbon ko don samun fa'ida kyauta!
