Rapid soliditied Alloys systems (Bulk amorphous alloys)

Preparation of bulk amorphous

Compact and economical design suitable for research and development
Best suitable for preparing high-strength and corrosion- resistant materials
Suitable for preparing cylindrical and plate-form amorphous alloy
By switching of a mold, this apparatus can be used for melting button-like alloy.

This systems is used for preparing bulk amorphous alloy by first melting metal materials with arc, drawing it down, and then inject it into a mold instantaneously.
