se S tib tiyo koule nan fòm ak segondè asye Manganèz. Sifas la fasil-chire si soude ak anti-mete. sifas enteryè nan tib la rantre fèt san pwoblèm epi ki konkrè ka koule libreman nan tib la, pli lwen amelyore pèfòmans nan ponpe. se arbr a kanle te fè nan alyaj epi li se sifas la espesyalman trete, amelyore pèfòmans nan nan anti-mete ak anti-fatig.
