Dental alloy for ceramic Cr and Co based.Absoloutely free from Nickel and Beryllium

This is a Cr-Co alloy for dntal use,Absolutely free from Nickel and Beryllium is perfectly bio-compatible with ceramics .By the use of this alloy it is obtained an optimal casting of great fluency.Easiness of working and the physical-chemical bond with dental ceramics today on the market are exceptional.Perfect corrosion resistance and high-quality soldering,Compared with BIOMATE K BEST.It introsuces greater Vickers hardness and support heavier yiels strength.Compared with BIOMAT K BEST,oxidation is lighter
