Why TA1, Not Ti-6Al-4V
Titanium for industrial use comes in many grades. The two relevant ones for jewelry are TA1 (Commercially Pure Grade 1) and Ti-6Al-4V (Grade 5).
TA1 is 99.5%+ pure titanium with no alloying additions. Maximum biocompatibility. The standard for surgical implants, dental implants, and pacemaker housings. Slightly softer than alloys, but more than strong enough for chains.
Ti-6Al-4V (Grade 5) is 90% titanium + 6% aluminum + 4% vanadium. Used in aerospace airframes and high-stress structural applications because of higher tensile strength. The aluminum content makes it less ideal for continuous skin contact in jewelry.
For chains, the strength advantage of Ti-6Al-4V is irrelevant, a chain is not subjected to aerospace stress loads, and the biocompatibility tradeoff matters. Maison AERO uses TA1 exclusively.
What Makes Titanium Different
The defining property of titanium is the TiO₂ oxide layer. When titanium meets oxygen (any time it is exposed to air), it instantly forms a microscopic layer of titanium dioxide on its surface. This layer is what prevents corrosion, blocks ion migration to skin, and resists chemical attack from sweat, chlorine, and saltwater.
The layer is also self-healing. If you scratch the surface, the freshly exposed titanium meets air and reforms the oxide layer within nanoseconds. This is the same property that allows titanium to remain stable inside the human body for decades as a surgical implant, it does not degrade, ever.
Compare to silver (tarnishes when copper reacts with sulfur), gold-plated (the plating wears off the base metal), and stainless steel (can pit in saltwater over years). Titanium does not have an analogous failure mode.

FREQUENTLY ASKED QUESTIONS
What is pure titanium jewelry?
Jewelry made from Commercially Pure Titanium (TA1, also called Grade 1), 99.5%+ pure titanium with no alloying additions. This is distinct from titanium alloys like Ti-6Al-4V (Grade 5), which contain aluminum and vanadium for added strength but compromise full biocompatibility. Pure titanium is the standard for skin-contact applications because it is hypoallergenic, lightweight, and biologically inert.
Why is titanium used for men’s jewelry?
Three reasons: weight, skin safety, and durability. Titanium is 45% lighter than stainless steel, meaning a substantial 22-inch Cuban chain feels almost weightless on the neck. It contains zero nickel, eliminating the most common cause of jewelry skin reactions. And it forms a self-healing oxide layer (TiO₂) that prevents corrosion, tarnish, and wear, the chain looks identical in year ten as on day one.
Is pure titanium expensive?
Raw titanium is roughly 10–15x cheaper per gram than gold but more expensive than stainless steel. The cost premium over steel comes from machining: titanium work-hardens under cutting tools and requires slower feeds and specialized tooling. A typical TA1 men’s chain at MAISON AERO ranges from $90 to $400 depending on width and style.
How can I verify a chain is pure titanium?
Three quick tests: weight (real titanium is ~45% lighter than steel for the same dimensions), magnet test (titanium is paramagnetic and will not stick to a strong neodymium magnet), and color (cool brushed gunmetal, not chrome-bright like steel, not yellow like gold). Reputable brands also publish their grade specification (look for TA1 or Grade 1 explicitly).
What is the difference between TA1 and Ti-6Al-4V?
TA1 is 99.5%+ pure titanium, maximum biocompatibility, used in jewelry and surgical implants. Ti-6Al-4V (Grade 5) is an alloy: 90% titanium + 6% aluminum + 4% vanadium. It is stronger than TA1 (used in aerospace and high-stress applications) but the aluminum content makes it less ideal for continuous skin contact. For chains, TA1 is the right grade because the strength advantage of Ti-6Al-4V is irrelevant for jewelry wear and the biocompatibility tradeoff matters.
Is pure titanium the same material used in implants?
Yes. TA1 titanium (Commercially Pure Grade 1) is the standard material for surgical implants, dental implants, and pacemaker housings. The body accepts pure titanium without rejection, bone tissue can actually bond directly to its surface (a property called osseointegration). When you wear a TA1 chain, you are wearing the same material a surgeon would place inside the body for life.
