Design Principles

"Material selection for high-temperature reactive metal processing requires a multi-factorial analysis of chemical, thermal, and mechanical stability."

In advanced manufacturing, particularly with reactive metals like titanium, the crucible is not merely a container but an active participant in the melting process. Understanding crucible-melt interactions and material stability is essential for achieving desired alloy properties and avoiding costly defects.

06

What This Means for Your Design

Choosing the right container (crucible) is super important when melting titanium alloys with induction heaters, because the wrong one can melt into the metal, break from heat changes, or make the final product impure.
