Non-precious dental alloy for ceramics for crowns and bridges. System KN is optimally suited for the inductive melting and can be used with any commercial, phosphate-bonded investments. Good flowability is a feature of the highly-noncorrosive and soft alloy.
System KN is characterized by a very good metal-ceramics compound (WAK 14,1 * 10 -6).
System KN is easy to polish, solder and laser. System KN can be blinded with any high-melting ceramic compounds.
