What Is The DART Made Of? Why Aerospace Aluminum and Medical-Grade Titanium Outlast Glass

Quick answer: Every DART is machined from metal, not glass. The DART MD, Plus, and Pro are made from aerospace-grade anodized aluminum, and the DART Pro Titanium is made from biomedical-grade titanium. Both metals are prized for the same reasons surgeons and aerospace engineers rely on them: they form a stable, inert, non-reactive oxide surface, they resist corrosion, and they do not shatter. Glass does none of those things.

Those material choices are not just about toughness. They are what make a precise, repeatable dose possible in the first place, because metal can be machined to exact tolerances that hand-formed glass cannot hold. Here is the science.

What is The DART actually made from?

There are two materials across the lineup, both chosen for how they behave under heat and daily wear.

The DART MD, DART Plus, and DART Pro are machined from aerospace-grade anodized aluminum, the same class of aluminum used in aircraft structures for its strength-to-weight ratio. The DART Pro Titanium is machined from biomedical-grade titanium, the same alloy family used in surgical and dental implants.

Neither is bare metal by the time it reaches you. Both wear a thin, hard, chemically stable oxide layer, and that layer is the key to why they are safe to draw through.

Are these metals safe to smoke from?

Yes, and the reason is surface chemistry. Both metals are protected by an oxide layer that is inert, non-porous, and non-reactive.

Anodized aluminum. Anodizing is an electrochemical process that thickens aluminum’s natural oxide skin into a hard layer of aluminum oxide (Al2O3) bonded to the metal itself, not painted on top. That layer is non-reactive and non-porous, which is exactly why anodized aluminum is used for food-contact cookware: it will not leach the underlying metal, even under heat or exposure to acids. It is also extremely hard, scoring roughly 300 to 600 on the Vickers hardness scale, versus about 150 to 200 for stainless steel.

Titanium. Titanium spontaneously forms a passive layer of titanium dioxide (TiO2) just a few nanometers thick the moment it meets air. That film is what gives titanium its famous corrosion resistance and biocompatibility. It is so well tolerated by the body that titanium is the standard material for orthopedic and dental implants, where bone tissue bonds directly to it, a property called osseointegration.

It is also worth retiring an old myth: the idea that aluminum exposure causes Alzheimer’s disease has been investigated in large studies for decades and dismissed by major research organizations. With an anodized, sealed oxide surface, there is no raw aluminum in contact with your smoke to begin with.

How does metal compare to glass?

Glass has one virtue, it is cheap to mold, and several real liabilities. The biggest is obvious to anyone who has dropped a glass piece: it shatters. Metal absorbs impact and keeps its shape. Beyond durability, the difference shows up across every property that matters for a pipe you carry and use daily.

Metal vs glass at a glance

The heat point deserves an honest note. Combustion happens at the burning ember, or “cherry,” of the packed herb, which can reach 900 degrees Celsius or more, hotter than aluminum’s melting point of 660 degrees. That ember never turns the pipe body into molten metal, because aluminum is an excellent thermal conductor and pulls heat away from the burn point, while the hard aluminum-oxide surface is far more heat-stable than the base metal. Titanium removes even that consideration: its melting point is 1,668 degrees Celsius, well above any cherry.

What makes anodized aluminum “aerospace grade”?

Aerospace-grade anodized aluminum is high-strength aluminum alloy that has been anodized, an electrochemical treatment that converts the surface into a thick, hard, corrosion-resistant layer of aluminum oxide. The result is a lightweight material with an exceptional strength-to-weight ratio and a sealed, inert surface, which is why it is used in aircraft and precision hardware.

In a pipe, that translates to thin, strong chamber walls that survive being dropped, a body light enough to carry unnoticed, and a surface that stays chemically stable through heat and repeated cleaning.

Why does the DART Pro Titanium use medical-grade titanium?

Because titanium is the most inert, durable material you can reasonably put in a handheld pipe. The specific alloy family used for implants, Ti-6Al-4V (Grade 5), combines high strength, fatigue resistance, and corrosion stability, and it is the most widely used titanium alloy in the medical industry for exactly those reasons.

For the DART Pro Titanium, that means superior heat dissipation, a premium feel, and effectively lifetime durability. You are drawing through the same class of material trusted inside the human body.

How do these materials make precise dosing possible?

This is the part most people miss. A DART MD holds 0.15 g. The DART Pro holds 0.25 g. The DART Plus holds 0.30 g. Those are not rough estimates, they are machined specifications, and they are only achievable because the pipes are made of metal.

Metal can be CNC-machined to tight, repeatable tolerances, which means every chamber of a given model is the same size, down to fractions of a millimeter. A fixed chamber volume is what turns “a pinch” into an actual, repeatable dose. Hand-blown and molded glass simply cannot hold those internal dimensions consistently, nor can it be made into the thin-walled, narrow, deep chamber a precise micro-dose requires without becoming dangerously fragile.

In other words, the material and the measurement are the same design decision. You cannot machine a reliable 0.15 g chamber out of glass. You can out of aerospace aluminum and titanium.

Frequently asked questions

Is it safe to smoke out of anodized aluminum?
Yes. Anodizing seals the aluminum under a hard, non-porous, non-reactive layer of aluminum oxide, the same reason the material is used for food-contact cookware. There is no raw aluminum in contact with the smoke, and it does not leach under heat.

Is titanium safe to smoke from?
Titanium is biocompatible and forms a stable, inert titanium-dioxide surface, which is why it is the standard material for surgical and dental implants. The DART Pro Titanium uses this same class of material.

Is a metal pipe better than glass?
For durability, portability, and dosing precision, yes. Metal does not shatter when dropped, can be machined to exact chamber tolerances, and lasts for years, while glass is brittle and inconsistent in its internal dimensions.

Does aluminum cause Alzheimer’s disease?
No. The aluminum-Alzheimer’s theory has been examined in large studies for decades and dismissed by major research organizations. An anodized surface also keeps raw aluminum out of contact entirely.

Why can’t glass pipes offer the same precise dosing?
Because glass is hand-blown or molded and cannot hold tight, repeatable internal dimensions. A precise chamber, such as the 0.15 g DART MD, requires CNC machining, which is only possible in metal.
