Normal Metal (Crystalline)

Amorphous Metal
Amorphous Metal (AM) has typical liquid-like atomic structure even after solidification, and it provides superior characteristics including mechanical, cosmetic and chemical properties. By having this atomic structure, Amorphous Metal has enough fluidity to fill the mold at relatively low temperature, to provide the great formability and productivity.
PrometalTech has achieved the best and matured technical capabilities to fully utilize the benefits of Amorphous Metals developed over past decades. We serve several AM materials into products to meet customer’s preference ; Zr-base alloys, Cu-base alloys, etc..
