Alumite
Repair Almost Any Metal With Just a Propane
TorchKapp Alumite is the original low-temperature fluxless
soldering & brazing rod for the fabrication, maintenance and repair of
Aluminum and Zinc alloys. Alumite has been used and endorsed by leading
manufacturers for over 40 years!!!
Actual field applications result in joints that are permanent,
non-corrosive and, in many cases, stronger than the parent metal. Alumite
will join most aluminum alloys, zinc based alloys, pot metal, and white
metal. It can also be used as a general purpose high strength solder.
