摘要
Dental alloy comprises by wt.% 9-37 Ni, 18-25 Cr; max. 11 Mo, max. 22 W; max. 1 Ti; max. 3 Nb, max. 20 Fe; max. 2 Mn; max. 1.5 Al; max.1 Si; bal Co plus usual impurities. The Mo content (a) and W content (b) also fulfill the conditions 2a+b is between 12 and 22. Pref. it contains less than 0.1 wt.% C and has a termal expansion coefft. at 20-600 deg.C of 14 x 10 power -6/deg K- 14.6 x 10 power -6/deg.K. ADVANTAGE - For blending with ceramic to produce false teeth crowns and bridges. Free from noble metals. e.g. Au but has comparable corrosion resistance to high Au alloys. Is workable and is chemically compatible with the body.
