WORLD OF TOOLS
creating better alloys
t
Technology department ensures metallurgical consistency
he Technology group at Stuller is a support group specializing
in alloy development, alloy processing and support of these
products after the sale. Two well staffed labs give us the capacity
to develop, maintain and support a large series of alloys used
by both internal and external customers. As a member of the
Technology Group at Stuller, I would like to share with you
a story that demonstrates how the Technology Group helps support the
Stuller promise to get you what you want, when you want it and how
you want it.
In the past year the cost of gold and platinum has forced consumers
to consider jewelry made from alternative metals. Since sterling silver
jewelry cost much less and is already established in the jewelry market
it became a natural choice. Stuller business units responded to the trend
and selected styles from an existing line to be offered in sterling silver. At
this point the Technology Group gets involved because of their expertise
of alloys and related process requirements.
Two requirements given to us were; the alloy had to 92.5% silver
and had to be more resistant to tarnish than standard sterling. Other
requirements we established were the mechanical properties had to meet
or exceed that of standard sterling silver and the alloy had be a match
to production equipment. Based on these requirements the Technology
Group selected two sterling alloys with increased tarnish resistance to be
tested along with standard sterling silver as a reference. Test patterns were
investment cast, visually inspected and alloy
properties such as color, hardness, ductility and
melt range were determined using an arsenal of
analytical gear found in the metallurgical lab.
Based upon the previously listed requirements
a #914 sterling silver alloy was chosen for
further testing.
The next stage of product development is
what I consider a maintenance stage, once an
alloy has been chosen parameters for melting
Randy Welch
stuller expert and casting the alloy need to be established. The
#914 sterling silver contains volatile elemental
additions that give it greater resistance to tarnishing, therefore special
melt practices were required to control the chemistry. A combination of
chemical analysis and inspection of cast parts were used to develop melt
procedures. Casting parameters and post treatment for the 914 sterling
silver were established by casting parts at various temperatures, surface
quality was evaluated and parts inspected for casting defects.
We stringently prepare and test new alloys, so you can work with
confidence. This means you receive the best performing alloy available
in the metal quality of your choice, when you need it, the way that you
want it, every time.

orking with Sterling Silver still
frustrates the average person to
no end from having to pull soft
delicate stones for a simple sizing,
to having to deal with heavilyplated silver the torch burns off. Then you have to
re-plate, risking rhodium contamination or chipping
or breaking the stone while re-setting. It is all too time
consuming for what is typically charged.
Using your laser can be the trick for this troubled but
popular metal. First cut or prep metal, then re-align the
pieces. Then use 3M Scotch Brite wheel (11-8280)
or Radial Bristle Brush (10-101) to remove the
shine from the desired welding area. (Using a marker to
darken the area can work, but it does not consistent draw
the energy into the metal as a roughed up surface will.)
Parameters on your Rofin laser, depending on thickness
of metal, should range from 280-300V, 4.5ms, focus
8-18 (very narrow focus can create a hole straight through
the metal). While prepping the piece, if the metal seems
spongy or overly porous, use a ramp-down pulse shape.
This will allow the metal to cool more slowly and form
a greater bond. When filling in the seam with wire,
using sterling weld hard wire instead of 925 Sterling.
As the 925 Sterling is very reflective, you would have
to use higher and higher voltage to flow the metal. This
leads to pitting and cracking in the piece. The slightly
lower silver content of the silver weld hard will flow at
lower voltage and with less splashing. Polishing should
leave your sterling ring nearly seamless.
With sterling, like costume jewelry, I always start
with a test shot at a lower voltage and work up from
there. This may take an extra two or three seconds of
my time but finding the exact temperature for each
piece will make stronger joints in the long run.
Welding plated rings should not be a problem.
Because the heat is isolated, you will not burn off the
plating. After finishing your weld, sand and prep the
seam as normal. But when polishing, only use red
rouge to prevent removing any other plating. This
should leave you with only a small area to pen plate
at the end.
