Upgraded 2-in-1 Soldering Combo
Now includes a special 10ml flux for Aluminum! Make clean, firm, and fully filled joints on aluminum, stainless steel, and nickel sheets with ease.
Why Two Bottles?
Aluminum has a highly stubborn oxide layer that normal fluxes can't penetrate. That's why we include a specialized 10ml strong formula JUST for aluminum, while the 50ml bottle safely handles your daily stainless steel, iron, and copper jobs. One combo, zero compromises.
Reliable Soldering on Hard-to-Weld Metals
Specially formulated to overcome the challenges of welding non-cohesive metals. It penetrates and breaks down tough oxide layers quickly, enabling solder tin to flow smoothly and create exceptionally strong bonds.
The Perfect Choice for Battery Pack Assembly
Enables direct soldering on 18650 lithium battery cells and nickel contact plates. Achieves low-resistance connections with solid joints, keeping your DIY or professional multi-cell battery builds secure and clean.
Controlled and Precise Liquid Dropper Nozzle
The compact bottle structure features a fine conical dropper cap, allowing you to dispense single droplets directly onto target seams without polluting surrounding elements or wasting material.
