Ferrotungstènese sitou itilize nan asye ak Distribisyon. Ferrotungsten se youn nan alyaj ki pi enpòtan pou pwodiksyon asye espesyal. Ferrotungsten pa sèlman ka diminye elongasyon an asye, men tou, ogmante limit fòs la ak pwen sede nan asye, osi byen ke amelyore dite a ak rezistans mete nan asye. Dezyèmman, ferrotungstène tou gen yon bon enpak sou pwopriyete segondè-tanperati mekanik asye. Li ka amelyore rezistans chalè ak tanperaman estabilite asye.
