347 ndi chitsulo chosapanga dzimbiri, pomwe 347h ndi mtundu wake waukulu kaboni. Malinga ndi kapangidwe kake,347imatha kuwoneka ngati alloy yochokera ku kuwonjezera kwa niobium kupita ku chitsulo chosapanga dzimbiri. Niobichi ndi chinthu chosowa kwambiri padziko lapansi chomwe chimagwiranso chimodzimodzi ndi Titanium. Mukawonjezeredwa ku chiloloya, itha kukonza zovala za tirigu, kukana kutupa, ndikulimbikitsa kuumitsa zaka.
