When body jewelry in made of high quality materials for use in studios, retailers or private label collections, the choice of materials is everything. We are a body piercing jewelry factory wholesale supply piercing jewelry, jewellery manufacturing OEM/ODM) and we have worked with many buyers who specifically demanding G23 titanium for it is strong, corrosion resistant and well known in the piercing industry when grade is made to implant grade standards.
This guide explains what G23 titanium is, how it behaves in actual use, and what the average buyer should know about this material when considering “titanium” options for piercings.
1) What is G23 titanium?
G23 titanium commonly refers to Titanium Grade 23, also known as Ti-6Al-4V ELI.
- G23 titanium is a common name that refers to Titanium Grade 23 (i.e. Ti-6Al-4V ELI). It means the alloy is composed primarily of titanium with aluminum (Al) and vanadium (V) as the main alloying elements.
- ELI is an acronym for ”Extra Low Interstitials” which means the alloy is made with reduced limits for certain minor elements that affect performance (such as oxygen and carbon), thus increasing toughness and ductility and making it suitable for more demanding applications.
G23 is Implant grade Titanium and recognized that quality of titanium for use in the body, but giant should always be rail then leave, Surgical Steel is good but really not for use.
2) Does G23 titanium tarnish?
In normal jewelry use, titanium is highly resistant to tarnish-like discoloration.
Why? Titanium is the only metal that also naturally forms a stable oxide layer on surface, a layer made from titanium TheSeries dioxide (TiO₂) acting as a protective film, which contributes to the high corrosion resistance of titanium alloys.
Nevertheless, buyers should keep their expectations in check:
- While titanium can certainly become dull with skin oils, soap film, and product residue (that’s not “tarnish,” that’s just gunk).
- A mild cleaning (mix of soap and water, make sure to dry it well) is generally sufficient to recover shine
3) Is G23 titanium hypoallergenic?
For sensitive individuals, titanium is a popular choice since it is considered less allergenic and a go to option when people’s skin reacts to metals that contain nickel.
But the safest way to say this is (especially in B2B):
- Hypoallergenic is dependent on the specific alloy + the finishing + the potential contamination.
- In guidelines for professional piercing, implant grade titanium classified to industry recognized standards is regarded as the material of choice for initial piercings
So yes-G23 titanium is frequently used for hypoallergenic status etc, but the real “trust signal” when wholesale is: certified standard compliance , and standardised manufacturing controls.
4) Is G23 titanium waterproof?
For all intense-and-use purposes, g23 titanium is pretty water friendly. The same corrosion-resisting surface film (TiO₂) allow titanium to be exposed to sweat, shower water and high humidity with the rare occurrence of rusting and accelerated discoloration
But “waterproof” for jewelry does have limits:
- Pool chlorine and other harsh cleaning solutions will eat away at any metal.
- After strenuous activity in the ocean or pool, or if perspiring heavily, polishing, cleaning, and drying does wonders in keeping the finish looking good.
5) Is G23 titanium safe for piercings?
Safety of materials in piercings is not determined by “titanium vs. not titanium” – it’s about whether the titanium is certified for implant applications and is made appropriately.
The Association of Professional Piercers (APP) recommends to check if your titanium is certified to meet ASTM or ISO standards for surgical implant use (including ASTM F136 and ISO 5832-3, among others).
That’s why many studios and distributors opt for implant-certified Ti-6Al-4V ELI as the preferred initial piercing material: it’s a recognized standard with defined chemical/mechanical properties opposed to the nebulous “titanium” label.
Note: This is not medical advice — what’s suitable for piercing depends on the individual and the professional aftercare. But from a supply perspective, adhering to implant-certified standards is the most defensible stance the industry can take.
6) What is the difference between regular titanium and implant grade titanium?
This question is critical for wholesale buyers of body jewelry.
“Regular titanium” (what it means in the market)
In jewelry descriptions, “titanium” may mean one of the following:
- Commercially pure titanium (there are different grades)
- Titanium alloys such as Ti-6Al-4V, sometimes without claiming standard conformance
What is ‘Implant grade titanium’?(basic overview)
Implant grade usually means the material complies with a recognized medical/implant standard, such as:
- ASTM F136: a specification for wrought annealed Ti-6Al-4V ELI for surgical implant applications
- ISO 5832-3: an international standard describing characteristics and test methods for wrought Ti-6Al-4V alloy used for surgical implants
In other words, implant grade is not a “marketing vibe” it’s a standards + documentation + traceability story.
7) The Difference Between G23 Titanium and ASTM F136 Titanium
This is where a lot of people get confused about terms:
- G23 (Grade 23) is the popular alloy grade name for Ti-6Al-4V ELI.
- ASTM F136 is a standard specification that establishes the chemical and mechanical properties for the wrought annealed Ti–6Al–4V ELI intended for surgical implants.
So, in practice:
- You can have a product touted as “G23 titanium,” but if it’s not F136-certified (or ISO equivalent) with full material traceability, it might not live up to the expectations of those who professionally purchase piercings for “implant grade.”
Additional topics that are influential for B2B buyers
Surface finish and machining quality
Even the best titanium can be disappointing if:
- edges are sharp
- polishing inconsistent
- threads are rough
- tolerances are sloppy
Finish quality is an important influence on comfort and healing with piercing jewelry, and not just the base metal
Color options: anodizing vs. coatings
Many titanium colors in piercing jewellery are due to anodizing (altering oxide thickness), not paint. Anodizing is preferred because it does not depend on a separate coating layer that can peel off.
What to request from a supplier
If you’re sourcing at scale, ask for:
- What to ask for from a supplier If you’re buying in bulk, request: material grade and standard (e.g., Ti-6Al-4V ELI / ASTM F136 or ISO 5832-3)
- mill test reports / certification paperwork
- production QC standards (tolerances, polish level, thread inspection)
- studio retail-friendly packaging options
Closure: Why the G23 Titanium for Wholesale Piercing Jewelry?
G23 titanium has gained its reputation for strength and corrosion resistance and is considered to be the standard for professional piercing especially when provided as implant certified Ti-6Al-4V ELI under specifications similar to ASTM F136.
If you want a long time production partner, we are body piercing jewelry manufacturer serving wholesale piercing jewellery production and OEM/ODM service for g23 titanium piercing lines – including customized designs, finishing, anodizing options and scalable manufacturing for brands and distributors.
