Available Platinum Alloys:
Platinum 95% Ruthenium 5%
Platinum 90%
Iridium 10%
Plat/S+
The first two options are very familiar to the trade, but we think
careful consideration should be given to Plat/S. Traditional
high-purity platinum alloys are soft and difficult to polish.
We offer 95% pure platinum alloy invented by designer and metallurgist
Steven Kretchmer originally for his Tension Set ring design. It is
harder than traditional platinum alloys. This makes it more resistant to
damage and wear. These characteristics also allow it to polish easier,
reducing polishing time by as much as 25%! The finish will last
longer. It‘s hardness and strength allows jewelers to use thinner
material. This significantly saves on material cost.
Plat/S+ can be work-hardened at a 35% faster rate and up to 50% harder
than platinum/iridium. This alloy is also designed to be heat-treated to
increase its hardness up to 50% from its annealed temper.
The superior characteristics of Plat/S allow tools to cut cleanly and
crisply, with much less tool wear. It machines and files without
grabbing. Although harder it can be rolled to one-third its thickness
without annealing.
