New ultra-white range of master alloys
The ultra-white range of master alloys by ProGold which can really be called
white gold
Polyhedric:
Blank is a range of universal master alloys planned
for the production of 18ct white gold items.
Precious:
the exclusive composition guarantees a fine grain microstructure
which increases the features and grants perceivable advantages in the production.
Crystalline:
the main feature of this family is to display an intensity
of white colour very close to Rhodium plating.
Main characteristics
- colour close to rhodium
- it allows a higher control of the grain growth during
annealing
- the scraps can be recast several times with very reduced fragility
problems
- reasonable growth of the grain dimension during continuous casting
-
drastic reduction of the shrinkage porosity and easy production of very bright and
smooth surfaces
- high mechanical resistance
- compact and top quality surfaces
