Dental Alloy ceramic Ni and Cr based.Free from Beryllium,Aallium and Cadmium
This alloy is Ni-based dental alloy, combained with Kinetic active elements Cr and Mo for the perfect passivation in corrosive enviorment.It is absoloutley free from Berylium,Gallium,Lantan,Cadmium,Lead.it is chareceterized by excellent corrosion resistance mechanical workability and solderability.It is well knew that perfect polishing allows supreme luster obtained with Ni base alloys.This alloy has a very wide applicability.The properties are very convenient for gold construction in model casting.Combined work and especially are adjusted to properties of modern ceramics for use in PFM(Porcelain Fused Metal) restoration
