Ubume bentsimbi obukumgangatho ophezulu, umphezulu owenziwe igalvanized, ipeyinti yepiyano kwipleyiti esezantsi, eyomelele kwaye eyomeleleyo yokuthwala umthamo.
Ivili elitsha le-Fuma elihlengahlengiswayo lidityanisiwe, liguquguqukayo kwi-deformation, i-high in wear resistance, inkulu kumthwalo, iphezulu ekuzinzeni, iyunifomu yokuthwala umthamo kunye nobubanzi boluhlu lwesicelo.
Ukusetyenziswa: La mavili alungele izixhobo zoomatshini, izixhobo ze-semiconductor, oomatshini bezonyango, iirakhi zekhompyuter, ifenitshala, izixhobo zoomatshini, njl.
