»   TEK-1


Non precious casting alloy based on cobalt for metal-ceramic accord. DIN EN ISO 22674, type 4.

TEK-1 LEG is an universal alloy for all kinds of crown and bridge frameworks. The low hardness allows an easy preparation, milling and polishing. This exceptional alloy is optimal for primary crowns and the secondary constructions according to the SILADENT TEK-1 one-piece-casting technology.
TEK-1 LEG can be used with all standard high-sintering bonding porcelains.
