go to www.handyharmancanada.com and you'll find a huge web page on all the alloys they produce plus the applications table for them. Brazing covers a huge range of metals and even some types of glass. This page is really full of information. The only advertisement is the suggested alloys are handy/harman products. That covers a huge range though. Good luck.

You might even be able to use Mapp gas instead of OA. This would be a super-cheap rig to set up.

Evel,

Oxy-Fuel brazing of Titanium for bike frames is not gonna work. At temps above 500 degrees C. Titanium (Alpha-beta alloys such as 6Al4V) has an affinity for (will absorb) oxygen, nitrogen, hydrogen out of the atmosphere or any contaminant on the surface of the metal. If the afore mentioned elements are absorbed the material will become embrittled and unusable. This stuff requires a vacume furnace.

Ti does make great bike frames, as does 4130, however, I don't think its a good idea to join the two of them together via a hot process.
