Me Yasa Za Mu Zabi Tubalan Carbon Magnesium Mu?
Tsarin samar da kayayyaki mai tsauri (daga zaɓin kayan aiki zuwa bayan sarrafawa) yana tabbatar da cewa tubalin carbon na magnesium ɗinmu yana da kyakkyawan aiki a cikin tanderun masana'antu masu zafi. Ko don masu canza ƙarfe, ladle, ko wasu kayan aiki masu zafi, samfuranmu na iya:
Jure yanayin zafi har zuwa 1800℃ ba tare da tausasawa ko nakasa ba.
Jure wa narkakken ƙarfe da zaizayar ƙasa, wanda hakan ke ƙara tsawon rayuwar wutar tanderun da kashi 30% ko fiye.
Rage yawan gyaran da farashin samarwa ga abokan ciniki.
Muna samar da mafita na musamman bisa ga nau'in tandar ku, girman ku, da yanayin aiki. Tuntuɓe mu a yau don ƙarin koyo game da tsarin samar da tubalin carbon na magnesium ɗinmu ko don samun ƙiyasin kyauta!
