Lomiga 3D Nickel Based Alloy Inconel 718 Pa'u
Fa'amatalaga o oloa
Inconel 718 paʻu o loʻo i ai le sphericity lelei, faʻafefe, maualalo le faʻafefeteina, maualuga le vevela o le faʻamaʻiina o le faʻamaʻiina, faʻamaʻi faʻamaʻi ma le ofuina.E ala i le tufaina o lapopo'a eseese.E mafai ona vaevaeina le pa'u fa'avae nikeli 718 i totonu o le pa'u fa'ameamea, le pa'u fa'apipi'i leisa, le pa'u pa'u, le pa'u vevela isostatic ma isi.

Faiga pulea lelei
Huarui o loʻo i ai faiga faʻapitoa tau pulega.Matou te suʻesuʻeina muamua a matou oloa pe a maeʻa a matou gaosiga, ma matou toe faʻataʻitaʻi aʻo leʻi tuʻuina atu uma, e oʻo lava i faʻataʻitaʻiga.Ma afai e te manaʻomia, matou te manaʻo e talia isi vaega e suʻe.Ioe pe afai e te fiafia i ai, e mafai ona matou tuʻuina atu faʻataʻitaʻiga ia oe e suʻe ai.
O a matou oloa lelei e faʻamaonia e Sichuan Metallurgical Institute ma Guangzhou Institute of Metal Research.O le galulue faʻatasi ma i latou e mafai ona faʻasaoina le tele o taimi suʻega mo tagata faʻatau.
