Alloys

Hinri-Alloy CoCr

Hinri-Alloy CoCr is a chromium cobalt molybdenum alloy for denture bases. It does not contain nickel or beryllium and complies with the norm for cobaltbased alloys. Hinri-Alloy CoCr is tissue-compatible, highly resistant to corrosion and biocompatible. Its excellent physical and technical properties allow delicate CrCo restorations.

package size:

Hinri-Alloy CoCr, 1.000 g / REF 893040


Technical Data

Hinri-Alloy CB

Hinri-Alloy CB is a non-precious, chromium cobalt-based bonding alloy. It does not contain any nickel, beryllium or gallium. Hinri-Alloy CB provides an economical alternative to precious metal and palladium-based alloys. Its low hardness of only 285 VH 10 allows Hinri-Alloy CB to be easily milled, which is an advantage when fabricating fixed units for fixed/ removable appliances.

package size:

Hinri-Alloy CB, 250 g / REF 893023
Hinri-Alloy CB, 500 g / REF 893022
Hinri-Alloy CB, 1.000 g / REF 893020


Hinri-Alloy N

Hinri-Alloy N is a non-precious, nickel-chrome-based bonding alloy. It does not contain any beryllium or gallium. Hinri-Alloy N provides an economical alternative to precious metal and palladium-based alloys. Its low hardness of only 185 VH 10 allows Hinri-Alloy N to be easily milled, which is an advantage when fabricating fixed units for fixed/removable appliances.

package size:

Hinri-Alloy N, 1.000 g / REF 893030
