FORMALLOY H – Cobalt Chrome Casting Alloy

FORMALLOY H
Cobalt Chrome Casting Alloy

Cobalt based alloys (non-precious) are used in the dental industry for making dental prosthesis. They are economical

alternative to Gold & Silver based alloys (precious) bur petform well due to their mechanical properties and biocompatibility.

President Dental manufactures a range of Non Precious Dental alloys using the continuous cast method. We have all the

relevant certificates such as 93/42/EEC&ISO 13485:2003 in order to manufacture dental base metal casting alloys.

Properties

– High corrosion resistant

– Bio-compability

– Easy processing and shaping due to it is excellent elasticity

– Superior mechanical characteristics with regard to precious metal alloy

– Melting in any kind of induction and centrifuge machine

– Easy fluidity control and hygiene

– Low thermal conductivity

– High purity, due to production is made in continuous casting process

– Permanent metallurgical quality control with modern controlling processes

– Pure alloys
