2mm Copper-Aluminum Flux Cored Wire – 300cm Brazing Rod, No Extra Flux Needed For AC & Refrigerator Repair

About This Product

This flux-cored wire makes brazing copper to aluminum super straightforward.

It's 2mm thick and 300cm long – enough for multiple repairs.
The core already contains flux powder, so you don't need to add anything extra.

Just open the package and start welding.
It melts at around 400°C, flows nicely, and creates a strong, smooth joint without pinholes.

Perfect for air conditioner condensers, evaporators, refrigerator lines, radiators, motors, and even battery connections.

To use it, clean the surfaces with sandpaper, heat the joint evenly with a torch, then apply the rod.

It'll melt and spread into the seam.
Once it cools, you're done – no post-cleaning fuss.
The flux residue is non-hygroscopic and stays put.

It's a solid choice for both pros and DIYers working on refrigeration systems, automotive parts, or household appliances.
Good fluidity, solid bonding, and easy handling – exactly what you need for quick fixes.
