Casting | JoiningThe safe NiCrMo bonding alloy.Girobond ® CBSA carbon- and beryllium-free NiCrMo bonding alloy for crowns and bridges (Type 3)corresponding to ISO 16744 and ISO 9693.HOMOGENEOUSThe optimized production process guarantees high homogeneity and reproducibility of theindividual alloy batches - and thus completely homogeneous finished dental restorations.GOOD-NATUREDGirobond ® CBS can be melted by any standard method used in dental technology. The alloyis distinguished by a melting and casting behavior which is easy to control. Furthermore, thelow slag formation during casting ensures neat castings and crucibles.SOFTWith a Vickers hardness of 185 (HV10) Girobond ® CBS is soft and therefore easy to mill.Thanks to the admixture of niobium, the dense surface can easily attain a high polish shine.SAFE... for the dental technician and for the patient!Girobond ® CBS convinces by optimum mechanical values. This alloy does not contain carbonand therefore is excellently suitable for laser welding.Due to the specific coefficient of thermal expansion, the use of facing porcelains is safe andwill not cause problems.The biocompatibility is comparable with non-corroding CoCrMo-alloys.

The ideal denture base alloy for the complete range of removable dental restorations.It was quite challenging to create a bonding alloy for the model casting technique that offers outstanding rigidity that issuitable for laser welding and is also easy to process. Here is the solution: Girocrom ® FH, an innovative alloy with idealmechanical properties but without carbon; thus, no cracks due to carbide precipitation will occur.With the laser welding technique, the dental technician maybenefit from the advantages of the most modern joiningtechnique which ensures a high degree of biocompatibility forthe patient. During laser welding, conventional alloys revealedthe dilemma of carbide precipitation in the weld due to theircarbon content.Carbon increases the stability of alloys. However, carbideprecipitation in laser welds mean a big problem regarding thematerial quality which often resulted in undesired cracks andfractures. AmannGirrbach now confronts these materials withthe new denture base alloy Girocrom ® FH with the new optimizedcompound. The result is extra-hard quality with minimal fracturerisk in clasped dentures.Girocrom ® FH is distinguished by the excellent biocompatibilityand corrosion resitance due to its unique compound. This alloyoffers a fine-grain structure resulting from the niobium content.Despite the high mechanical values, Girocrom ® FH offers anextremely low Vickers hardness. Therefore, it is easier toprocess and to polish.Proof stress Proof stress Rp 0,2% (MPa) - different CoCr-alloys for partical denture750700650600550500710< 0,02GirocromFHCarbon free688< 0,02610< 0,05CompetitorA B701< 0,2Containing carbonCompetitorC D720< 0,8580< 0,04CompetitorE F679< 1,0SUMMARY_ Extra-hard denture base alloy_ Improved stability_ Suitable for all kinds of removable restorations, e.g. metaldenture bases, combined fixed-removable restorations,telescopic cases, dentures with slide attachmentsor clasps_ Easily activated clasps at model casting dentures, withminimized fracture risk_ Carbon-free and, thus, ideal for laser welding_ Easy processing and polishing; relatively low Vickershardness HV10 of 350_ Excellent biocompatibility and corrosion resistance
