Bayani: T107 wani lantarki ne mai tsabta na jan ƙarfe wanda ke da jan ƙarfe mai tsabta a matsayin tsakiya kuma an rufe shi da ƙarancin hydrogen sodium irin flux. Yi amfani da DCEP (mai kyau ga lantarki kai tsaye). Kyakkyawan halayen injiniya, kyakkyawan juriya ga tsatsa ga yanayi da ruwan teku, ba ya dace da walda jan ƙarfe mai ɗauke da iskar oxygen da jan ƙarfe mai electrolytic ba.
Aikace-aikace: Ana amfani da shi galibi don walda sassan tagulla kamar sandunan jan ƙarfe masu sarrafawa, na'urorin musanya zafi na jan ƙarfe, da hanyoyin ruwa na teku ga jiragen ruwa. Hakanan ana iya amfani da shi don walda saman sassan ƙarfe masu jure wa tsatsa na ruwan teku.
