Mesa Magnum Clarum Dental Alloy
Mesa’s alloys for ceramics comply with standards ISO 9693-1:2012 and ISO 22674:2016. They do not contain any toxic elements and, in the case of cobalt-based alloys, they are absolutely nickel-free.
Mesa’s alloys for ceramics are all highly resistant to corrosion and heat with a low conductivity.
Those alloys are characterized by their flexibility (the double if compared to noble metals) and by a good fluidity, enabling to obtain castings of a thickness as low as two tenths of a millimeter. Furthermore, thanks to their thermal expansion coefficient, they are ideal to be used with all last-generation ceramics.
