Comparing Titanium And
Tungsten Wedding RingsBoth
titanium and tungsten are considered “model metals” in the
jewelry industry because they were not available to the
consumer market as commodities until ten years ago. They
have gained tremendous popularity since the introduction
and become an integral part of the jewelry material
spectrum.
Due to the rather little exposure, many questions arise
concerning titanium and tungsten when it comes to choosing
jewelry. The followings are some points of consideration if you
are seriously thinking about buying a titanium or tungsten
wedding ring.
1. Hardness
Titanium and tungsten are both known for the superior hardness
over traditional metals such as gold, silver and platinum. One
thing worth noting is that it is not the metals themselves in a
pure form that possess the hardness, it is their alloys that
do. Roughly speaking, the hardest form of tungsten carbide is
harder than titanium alloys, and only under extreme
circumstances, such as abrasion from diamonds, can it be
damaged.
2. Ductility
Titanium is more ductile than tungsten in the common alloys
used in jewelry. In other words, when a wedding ring is under
high pressure, such as hit by a car door, a titanium ring would
be bend out-of-round whereas a tungsten carbide ring would
fracture into several pieces. Hence, in terms of safety, a
tungsten carbide ring is “safer” to wear.
3. Hypoallergenic
This is the very same concern as buying silver jewelry to some
people: Will I be allergic to the jewelry? In general, titanium
jewelry is virtually safe to wear for everybody. Yet, some
tungsten carbide jewelry contains the element cobalt that some
people are allergic to. Interesting, another form of tungsten
alloy using nickel as a binder metal is hypoallergenic, even to
people who are allergic to nickel.
4. Weight
Titanium is lighter than tungsten, or more precisely, has a
lower density. Titanium alloys are about 43% lighter than
stainless steel and tungsten carbide is about 90% heavier than
stainless steel.
5. Coloring
Titanium reacts with different chemicals and produces alloys of
different colors. Jewelry makers use anodization to coat
colored patterns on titanium rings. Black titanium is another
form of titanium alloy that has a different color than the
commonly used grey color. On the other hand, tungsten carbide
is usually offered on in black color only.
6. Pricing
Titanium jewelry is in general cheaper than tungsten jewelry
primarily due to the difference in equipment and environment
control need to produce them. The temperature for forming a
tungsten carbide is about 6000 Fahrenheit, which has to be in
either a vacuum or hydrogen environment.
7. Engraving and resizing
Titanium wedding rings can be engraved and resized. However, a
tungsten carbide ring is too hard to be engraved or resized.
Although engraving can be done, the letters will be very faint
and difficult to read. So if you are buying to ring to engrave,
get titanium rings.
