DESCRIPTION
Type 4 in accordance with ISO 22674
Excellent flowability, allowing dental technicians to cast even large quantities of alloy with maximum precision in every part of the restoration
Low melting point and very low solidus-liquidus temperature compared to standard cobalt-chromium alloys
Clear oxidation, good workability, easy polishing.
Can also be used for creating bars and counter bars.
