C&B:Cu-Al
nized worldwide as the gold alterna- tive—and has been for 25 years. NPG and NPG+2 are unique
alloys; formally the only formulations of their type to be Accepted by the American Dental Association's Council on Dental Materials, in 1989 and 1998 respectively. NPG offers the appearance and handling characteris- tics of precious Type III yellow-gold alloys, but at a fraction of the cost. Your laboratory will benefit from smooth and accurate NPG castings, providing reliable quality and fit. NPG
is simple to finish, and soldering is trouble-free with our specially formulated Aalba Gold Solder and Aalba Flux.
The bio-compatibility of NPG has been established through extensive in-vitro corrosion and biological
studies. With over 25 years of clinical service, NPG has been proven to offer patients reliability, durability, comfort and safety.
