Cina OEM custom ductile matak castings beusi kuprosés casting investasi lilin leungit. Beusi ulet, anu ogé katelah beusi tuang ductil, beusi nodular, beusi grafit spheroidal, beusi tuang grafit spheroidal, atanapi ngan ukur beusi SG.Lamun grafit hadir salaku partikel leutik, buleud, jeung well-disebarkeun, pangaruh weakening na leutik tur beusi tuang sapertos bakal boga ductility luhur. Jenis beusi tuang ieu disebut beusi ductile atanapi nodular atanapi grafit spheroidal atanapi ngan saukur beusi SG. Bentuk grafit ieu tiasa dihontal ku cara nambihan unsur magnésium atanapi cerium atanapi kombinasi dua unsur éta kana beusi tuang. Magnésium ditambahkeun dina jumlah 0,07 mun 0. 10% dituturkeun ku tambahan ferro-silikon pikeun ngamajukeun graphitization. Salila solidifikasi, magnésium mantuan dina distribusi grafit sakuliah logam.
Beusi ulet boga rasio kakuatan-to-beurat hadé, machinability hadé tur nilai dampak luhur. Leuwih ti éta, komponén beusi ductile dihasilkeun ku prosés casting wherein kontrol hadé bentuk komponén bisa dihontal dibandingkeun teundeun forging. Ku kituna, loba komponén kayaning shafts engkol jeung rod nyambungkeun dijieun biasana ku serelek forging beuki diganti ku castings beusi ductile.
