Non Gamma-2, Zinc free,
spherical dental amalgam
PROPERTIES
Silver Alloy is a non gamma-2,
Zinc free, single spherical
composition Silver alloy.
It consists of fine and ultra fine
particles which give a strikingly
smooth and adaptable alloy when
amalgamated with Mercury.
Alloy / Mercury ratio 1:1
The composition of Silver Alloy
avoids the corrosive gamma-2
phase (Sn8 Hg) formed with
conventional Silver amalgams.
