Overview
A hobbyist or repair tech joining aluminum parts gets a matched solder alloy and STAY CLEAN flux in one kit. It works with a torch or iron, forms corrosion resistant joints and gives a good color match on aluminum and zinc die-cast.
Joining hard to solder aluminum is the reason to buy, with strong, color matched joints. Magnesium is excluded, and the process needs careful indirect heating to avoid burning the flux.
Who it's for
Fabricators and hobbyists fixing aluminum castings, trim and fittings. Those working on magnesium parts need a different process.
Pros and cons
- Joins tough aluminum alloys
- Works with torch or iron
- Good color match on aluminum
- Corrosion resistant joints
- Not for magnesium
- Flux residue needs scrubbing
- Small quantity of solder
Performance notes
Joint strength depends on preparation and heat: the flux cleans the aluminum, indirect heat brings it to the right point, and the alloy flows between its solidus and liquidus. Stopping heat once it flows prevents overheating.
