PFM:Ni-Cr-Nb
free alloys, unparalleled homogeneity, and precise alloy chemistry. Comandium II's 14.3 CTE is optimized for major porcelain brands such as Ceramco, Noritake, as well as other medium-grain porcelains. Comandium II's CTE conforms to many
major porcelain brands; after firing, the porcelain remains in favorable compres- sion, not over stressed.
common to all porcelains. Titanium also improves anti-greening effects for more esthetic restorations. For further economy, Comandium II is also available in a non-branded 200 gram package.
Use Comandium II with confidence.
With its small, efficient ingot design (4.90g), Comandium II melts fast, minimizing gas and oxide formation.
