SYSTEM Duro is a nickel- and beryllium-free dental alloy on cobalt base for ceramics.SYSTEM Duro is easy to polish, good to solder and can be lasered without restrictions. SYSTEM Duro can be used with any commercial, phosphate-bonded investments (our recommendation: Adenta®-Vest CB) and is optimally suited for the inductive melting. SYSTEM Duro can be blinded with any high-melting ceramic compound.
