What Is Tix Flux? The Science Behind a Superior Liquid Flux

Tix Flux is a specialized liquid de-oxidizing agent formulated to clean metals and allow solder to flow smoothly and evenly—an absolute must when dealing with tiny, precise model parts or delicate metal alloys.

Key Features of Tix Flux

• Resists corrosion when neutralized with baking soda (bicarbonate of soda)

• Works on nearly all metals and alloys

• Perfect for brass, nickel silver, copper, stainless steel, and photo-etch

• Enables superior solder flow even at low temperatures

• Compatible with all soft solders—though optimized for Tix Solder

Unlike thick paste fluxes that can burn, char, or leave residue, Tix Flux applies as a thin liquid film, offering high precision and allowing capillary action to work at its best.
This is critical when soldering:

• Brass model train kits

• Etched metal locomotive details

• Photo-etch (PE) ship and armor parts

• Scratch-built metal components

• Fine wire work

• Micro-electronics additions to models (lights, decoders, LEDs)

Its thin viscosity gives the hobbyist total control—no globs, no excess, just clean, sharp solder joints.

Why Model Railroaders & Scale Modelers Love Tix Products

Tix products have long been a favorite among builders of brass locomotives, rolling stock, structure kits, and fine railroad details. The low melting point of Tix Solder and the high-performance cleaning action of Tix Flux make them uniquely suited for:

1. Brass Locomotive Kits

Whether assembling brass boilers, cabs, tenders, or adding aftermarket details, the goal is always the same: strong joints that don’t warp.
Because Tix Solder melts at just 275°F, far lower than most solders, it helps prevent:

• Warping thin brass

• Melting delicate detail castings

• Burning off factory plating

• Distorting alignment

2. Photo-Etch Add-Ons

Ships, tanks, aircraft, and trains all use photo-etched parts—often fragile and extremely thin.
Tix allows joints to form instantly without overheating or damaging the PE fret.

3. Repairs & Restorations

Vintage trains, die-cast locomotives, and classic metal structures often require repairs that can’t be trusted to superglue alone.
Tix Flux + Tix Solder create metal-to-metal joints that last decades.

4. Diorama & Scenic Structures

Metal signage, light posts, railings, ladders, trusses, and detail parts benefit from solder rather than glue—especially for transport, gaming, or show displays.

How Tix Flux Works: Step-By-Step for the Best Possible Joint

Using Tix Flux correctly makes the difference between a perfect fillet joint and a messy blob. Here’s a precise workflow:

Step 1 — Clean the Metal

A polished metal surface wets better. Use:

• 600–1200 grit sandpaper

• A fiberglass pen

• A brass brush

Remove oxidation, oils, fingerprints.

Step 2 — Apply Tix Flux Sparingly

A small brush or micro-applicator is ideal.
The flux’s surface-wetting ability means you don’t need a lot—a thin film is enough.

Step 3 — Heat the Metal, Not the Flux

For stainless steel applications, heat the metal first, then apply the flux.
You want the metal to draw in the solder through capillary action.

Step 4 — Introduce Tix Solder

Tix Solder melts at 275°F, the lowest of any commonly available soft solder.
It flows cleanly and forms extremely strong joints.

Step 5 — Neutralize Residue

Once finished, wipe the area with a bicarbonate of soda (baking soda) solution to neutralize any remaining flux.
This prevents corrosion and keeps your models looking flawless for decades.

Why Tix Solder Has One of the Lowest Melting Points in the Industry

The chemistry of Tix Solder is built for delicate work. Many common solders melt near 400°F or higher, risking damage to heat-sensitive materials.
By contrast, Tix Solder melts at just 275°F, providing:

Precision

It only flows where you want it.

Safety for thin metals

Avoid buckling and distortion.

Improved control

You can tack, reposition, and final-fit parts without overheating.

Better for painted or pre-finished surfaces

(Masking still recommended.)

This is a big reason why professional brass locomotive builders prefer Tix products.

Tix Anti-Flux: An Underrated Tool for Perfect Joints

One of the unique offerings from Tix is Anti-Flux, a chemical that prevents solder from flowing into unwanted areas.

Why Modelers Use Anti-Flux

• Keeps solder away from detail rivets

• Prevents solder from creeping up handrails

• Helps maintain crisp lines on brass kits

• Essential for gearboxes, joints, and articulation points

When working with tight mechanical tolerances, Tix Anti-Flux can save you hours of cleanup.

Tix Solder + Tix Flux vs. Traditional Soldering Methods

For hobbyists, the Tix system isn’t just easier—it’s safer on your models and more reliable long-term.

As a dedicated hobby store with deep roots in the model railroading community, Fusion Scale Hobbies sees firsthand why Tix remains a top choice among O, HO, N, G, and S scale builders.

1. Fixing Handrails, Steps & Grab Irons

Tix Flux helps create clean, invisible joints on brass or nickel-silver handrails.

2. Locomotive Brass Kit Assembly

Many professional builders use Tix exclusively for assembling entire locomotives.

3. Re-Soldering Electrical Pickups

Tix works incredibly well for delicate electrical parts due to its low heat requirements.

4. Attaching Detail Castings

Precision parts attach cleanly without melting nearby components.

5. Scratch-Building Structures

Metal trusses, rafters, jigs, fixtures, and frames benefit greatly from Tix’s clean joints.

Tix Flux in Miniatures, Wargaming & Figure Modeling

While many modelers know Tix from the railroad world, these products are exceptional for:

• Miniature figure repairs

• Metallic weapon sprues

• Pinning resin models

• Brass or metal reinforcement

• Diorama lighting builds

• Electronics for LEDs in figures and bases

• Armor turret detail repairs

• Ship model PE railings

Tabletop gamers and scale modelers can confidently solder pieces that glue alone won’t hold.

Expert Tips for Getting the Most from Tix Soldering Solutions

Use a Fine-Tip Iron

A 15–25W iron or a temperature-controlled station set to low heat is ideal.

Use Minimal Solder

Tix flows so efficiently that very little solder is needed.

Use Capillary Action to Your Advantage

Place parts together tightly and let the solder wick between them.

Avoid Over-Fluxing

More flux doesn’t mean better joints—the chemistry is strong enough without excess.

Neutralize and Rinse After Soldering

This ensures decades-long corrosion-free results.
