Alloy dental material PROALLOY

for dental restorationsfor root canal filling

PROALLOY is a dental silver alloy, rich in silver (70%), free of the corrosive gamma–2 (γ-2) phase (Sn8Hg) and does not contain zinc. It is characterized by its high resistance to corrosion and therefore reduces the risk of marginal fracture. PROALLOY is a single composition alloy, which guarantees that each individual particle is an alloy of exactly the same composition.It consists of fine and ultra fine particles giving a strikingly smooth paste when amalgamated with mercury. Its handling characteristics and resistance to corrosion have included it amongst the best amalgams in the world market. Chemical Composition Silver (Ag) 70%, Tin (Sn) 18%, Copper (Cu) 12% Particle Shape-Spherical Ratio – Alloy : Hg = 1 : 1.01 Characteristics - Advantages Excellent handling characteristics High resistance to corrosion Long lasting luster Excellent marginal adaptation High resistance to wear Indications Posterior restorations Technical Data Compressive strength 1 hour (MPa) - 220 Compressive strength 24 hour (MPa) - 500 Static creep (%) - 0.14 Dimensional change (%) - 0.015 Working time - 4'30"- 5'00" Trituration time - Silamat mixer - 8"
