Fidget Slider Materials Guide: Ti, Zirconium, Brass (2026)

Why material matters more than you'd think

Two sliders can share the same magnets and the same plates and still feel like different objects. The body material sets how heavy the slider sits in your hand, how the click lands, how it sounds, and what it looks like after a year in a pocket.

The single number that explains most of this is density. Here are the common fidget slider materials, from the reference values on Wikipedia:

Sources: aluminium, Ti-6Al-4V, zirconium, stainless steel, brass and copper on Wikipedia. The sound column follows Kickup's plate guide, which describes stainless as "heavy and affordable with a crisp sound" and titanium as "lightweight with a softer, smoother slide" (Kickup). We found no reliable sound comparison for the other metals, so we left those cells open; design matters as much as material.

Same design, different metal: real weights

Density tables are abstract. Here is what the difference looks like on sliders sold in more than one material:

• Bpmods Nine Palaces: 75.8 g in stainless steel, 48 g in titanium (GEEONE).
• MS EDC Silent Slider: 103.6 g in stainless steel, 85.6 g in zirconium (GEEONE).
• Lautie Choc: around 25 g in PEEK up to over 90 g for a Zircuti limited edition, with everyday metal versions at 55 to 65 g, per retailer TRB Creation (TRB guide).

The weights don't scale exactly with density, because magnets, plates and screws weigh the same in every version. Still, the gap is big enough to notice the moment you pick one up.

Material by material

Titanium

A titanium fidget slider that lists its grade is usually Grade 5 (Ti-6Al-4V); Umburry, for example, specifies Grade 5 for its titanium haptic coins (Umburry). Wikipedia notes that titanium is "60% denser than aluminium, but more than twice as strong as the most commonly used 6061-T6 aluminium alloy" (Titanium). In the hand that means light enough to forget in a pocket, but still solid.

Titanium's party trick is color. Anodizing grows a thin oxide layer whose color comes from light interference, so no dye is involved; the color depends on the oxide thickness, which is set by voltage (Anodizing). Urban EDC notes the color won't fade from UV or heat, but does wear through at high-contact spots, and lower-voltage golds and bronzes hold up better than blues and greens (Urban EDC).

Flame coloring, where the metal is heated with a torch to get gold, blue and purple tones, is simpler than anodizing, but Tiger Titanium says the colors "may be less durable" (Tiger Titanium).

Buy titanium if you carry all day and want low weight with no upkeep.

Zirconium

A zirconium fidget slider is roughly 44% denser than Grade 5 titanium (Urban EDC), so it sits heavier and feels more planted. Raw zirconium has "a silvery shiny look that resembles steel" (Böker). The black look people buy it for comes from heat treatment: as the part cools, the surface oxidizes into a black layer that, as Urban EDC puts it, "becomes part of the zirconium" rather than being applied on top.

That oxide is hard and shrugs off light scuffs, but the metal beneath is soft. Something sharp enough to cut through shows silver. Glossy oxide also shows fingerprints, so a microfiber cloth is part of owning one.

Price is the catch. Urban EDC lists several reasons zirconium costs more than titanium, including tighter supply, flammable machining dust that requires safety precautions, and extra finishing work. For scale, Magnus lists a titanium SweepX at $277 and a zirconium Turtle "Fine Golf" at $297 (SweepX, Turtle).

Buy zirconium if you like a heavy, dark slider and don't mind wiping it down.

Stainless steel

Stainless gets its corrosion resistance from at least 10.5% chromium forming a passive film that "can self-heal when exposed to oxygen" (Stainless steel). It is heavy and crisp-sounding, and Kickup calls it the affordable option among plate metals.

Buy stainless if you want weight and a crisp click on a budget.

Brass and copper

A brass fidget slider is heavy and warm in the hand, and it changes over time. Brass can darken and, with moisture, form "a patina of green-blue copper carbonate," which can also slow further corrosion (Brass). Copper goes brown-black first and can turn green later (Copper).

This is a matter of taste. Some people buy brass for the patina; others polish it back. Cutting material away helps with the weight: Magnus's skeletonized SkellyVerkk weighs 67 g in brass and 70 g in copper (brass, copper).

Buy brass or copper if you want the heaviest feel and like a slider that shows its history.

Aluminum and polymers

An aluminum fidget slider is the lightest metal option at 2.70 g/cm³, "about one-third that of steel" (Aluminium). Anodized aluminum takes almost any dyed color, but the anodized surface has "low to moderate wear resistance" (Anodizing). Lautie offers an aluminum Choc with a micro-arc oxidation finish, a different oxide process (Lautie).

Polymers like PEEK, PEI and G10, all offered as Choc versions, are lighter still. They make sense if you want something you can barely feel in a pocket.

Finishes: what they look like and how they wear

The finish often matters more to how a slider looks after a year than the metal itself.

• Stonewash. Tumbled with abrasive media for a matte, "deliberately worn" texture. New scratches blend in, which makes it the most forgiving finish for pocket carry (Urban EDC).
• Bead blast / matte. The lowest-glare look. Urban EDC warns that on steel the micro-pitted surface can become a starting point for corrosion.
• Satin and polished. Look sharp out of the box and show scratches readily. Satin can be restored with progressively finer sandpaper.
• Anodized (titanium or aluminum). Colors without paint. Titanium's color is interference; aluminum's is dyed. Both wear first at edges.
• Heat-oxidized black (zirconium). Hard, dark, scuff-resistant, but only surface-deep.
• Bluing / black oxide (steel). Wikipedia describes it as a black oxide "typically no thicker than 2.5 micrometres" that gives minimal rust protection unless oiled, and friction removes it over time (Bluing). Expect it to wear to silver at the edges.
• DLC and PVD coatings. Hard, uniform dark coatings. Urban EDC notes that DLC is very hard, and marks that look like scratches are often transferred material that wipes away.

Common mistakes

• Choosing zirconium for weight alone. If you mostly want heft, stainless or brass gets you there for less.
• Picking polished for pocket carry. It will not stay polished. Stonewash or a dark oxide hides wear.
• Blaming the metal for a bad click. The body material shapes the feel, but magnets, plates and tolerances decide the click. We cover that in our haptic fidget slider guide and magnetic vs mechanical comparison.

Where echoPi fits

With echoPi we have focused on the clicks: seven real, programmable clicks as a design target, where you choose how many clicks there are and where they sit. It is still in development, and the images on our site are concept renders, so there is no final material or price to share yet. If you want to hear where it goes, join the list.
