The technical team has been engaged in the preparation of rare metal spherical powders and the production of high-performance powder metallurgy products for a long time.
Saisu uses high-purity argon gas atomization and plasma rotating electrode atomization technology to prepare high-quality spherical rare metal powders, including titanium alloys, Ti Al alloys, Ti2AlNb, Ti Ta alloys, Ti Nb (- Zr) alloys, niobium alloys, tantalum alloys, etc. The powder has low oxygen content, high sphericity, good flowability, and stable performance, which can well meet the different needs of processes such as electron beam powder 3D printing, laser powder 3D printing, and laser coaxial powder feeding 3D printing.
Types of powder that can be produced:
TiAl powder: Ti48Al2Cr2Nb, Ti2AlNb, Ti45Al8Nb
Titanium alloy powder: CP Ti, TC4, TC4ELI, TA7ELI, TC11
Medical powders: TiTaNbZr, TiNbZr, NiTi, CoCrMo
Refractory, high entropy alloy powders: Stellite, Nb521, Ti Ta, Ta, W
