BODY JEWELRY MATERIALS
American Society for Testing and Materials
ISO - International Organization of Standardization
The ASTM and ISO are standardization
organizations that are made up of representatives from government,
academia and the private sector. They develop procedures, specifications
and criteria to be applied to materials, the manufacture of products and
the testing and analysis of those materials and products. These
organizations exist to benefit society as a whole and to promote health
316L ASTM F-138-03 -
99% of our jewelry is manufactured using 316L IMPLANT GRADE steel
unless otherwise noted. 316L is the most widely used because it is
affordable, durable and non-corrosive. All of our steel jewelry is
precision machined, gently tapered and mirror polished.
316L(VM) ASTM F-138-03 * ISO:5832-1 - VM stands for Vacuum Melting.
It is not part of the ASTM F-138 specification. Vacuum Melting means that
the metal has been melted or alloyed in a vacuum, thereby limiting outside
contaminants and reducing includions within the metal. This makes the
metal more pure. VM is not required for 316L to pass implant standards.
There isn't a lab test that can be performed to determine whether or not a
metal has been vacuum melted. There is no definitive, ASTM method to test
for vacuum melting.
TITANIUM 6ALV-ELI ASTM F-136-02 (Grade 23) - We use 6AL4V-ELi
IMPLANT GRADE titanium in all of our titanium body jewelry. Titanium
is becoming the metal of choice for most piercers. Because of its superior
machinability and lighter weight (45% lighter than steel) and almost
completely hypo-allergenic, Titanium is most ideal for individuals
sensitive to other materials.
TITANIUM 6AL4V ASTM F-136-02 (Grade 5) The essential difference
between Ti6Al4V ELI (grade 23) and Ti6Al4V (grade 5) is the reduction of
oxygen content to 0.13% (maximum) in grade 23. This confers improved
ductility and fracture toughness, with some reduction in strength.
* Titanium can be
polished to a high luster resembling that of 316L Implant Grade
Stainless Steel. It can also be colored by a process called ANODIZATION.
Anodizing is a process whereby an electrical current is passed through
the metal. Oxides build on the surface of the metal, and as light is
refracted through this film, a wide spectrum of vivid metallic colors
NIOBIUM - Niobium is
a pure element- not an alloy. In this Natural state it is completely
hypoallergenic and easy to bend making it ideal for use in jewelry
STERLING SILVER - Sterling Silvers chemical composition doesn't
allow it to be used for components that are inserted into the body. All of
our sterling silver jewelry has a surgical steel shaft which it is
attached to. Our Silver carries the hallmark .925 stamp which you can
actually see on most of the silver designs. Unlike imposters out there who
only do a silver coating, our Silver designs are truly Sterling Silver.
Teflon (PTFE, polytetrafluoroethylene) - Teflon is an inert
wear-resistant, slippery and flexible plastic, and has been used
extensively as a component of permanent and temporary surgical implants.
Benefits of PTFE:
1) Can be Sterilized with Autoclave
2) Totally Flexible - It will bend with your body tissues unlike all metal
3) Hypo-allergenic - Being one of the least allergic materials, P.T.F.E.
is used in the medical industry to make Heart Valves and other surgical
implants. Should there be a problem of allergic reaction or rejection to
conventional metal jewelry, it is likely that PTFE Body Jewelry is now a
practical choice for that person under any circumstances.
4) Fully Adjustable- A razorblade is all that is needed to adjust the bar
to the exact size of your piercing!
5) Self Threading - PTFE bars will fit all threaded accessories that you
may already own! Simply screw-on your accessory (balls, spikes, etc...) on
to a PTFE bar. It will create a thread on the bar and will hold strongly.
NYLON POLYMIDE MONOFILAMENT - Monofilament is used in medical
applications, in wig making and most commonly known, fishing line.
Monofilament is a single strand (hence... mono) of nylon. There is nothing
to fragment or splinter. The type of monofilament we use is called
monofilament nylon polyamide. It is strong flexible and non-biodegradable
(will not break down even with prolonged wear in the human body). This is
the same material used in non-absorbable suture material. Monofilament
nylon polymide is listed with the FDA as 'non-absorbable suture materials'
under nylon - listing no - A 100568.
