SUITABLE APPLICATIONS & PERFORMANCE
- Rich Red Gold Investment Casting
Metallurgical Characteristics & Casting Behavior
LEGA 18RC is meticulously engineered by Legamelt Alloys S.r.l. using high-purity virgin raw metals and advanced de-oxidation agents. It is specially designed to eliminate oxide inclusions, enhance molten metal flowability, and ensure zero porosity during lost-wax investment casting.
Whether used in automated continuous casting lines, closed vacuum induction machines, or open torch melting, LEGA 18RC provides exceptional color consistency across multi-batch productions and preserves mechanical ductility for post-casting stone setting and sizing operations.
