can this be for brazing copper to steel like refrigerator condenser coils,because i read condenser coil are not completely copper.

Condenser coils come in copper, aluminum and stainless. You can use SSWF on stainless and copper condenser coil. You would need an aluminum brazing rod and Albraze flux for aluminum coils. If determined the braze was going to be copper to copper, then a phos copper would be an even better recommendation and no flux needed. Thank you-BuyWelding Team

Does this contain any phosphorus? (Phosphorus is not allowed for propane applications)

I’m quite certain it does not. I use it to join brass, bronze, and copper with silver and I typically use a propane torch, but I use it to build models and other such items not plumbing or refrigeration work. It can be used to join phosphorus bearing metals though with the exception of Aluminium and magnesium.

I am brazing stainless to same stainless. Is white or black flux better?

Either will work. If you're brazing a thick piece of stainless that will take a lot of heat, you should use the black flux.

Will this corrode electrical wire?

I would not recommend using this product on electrical wiring, it is a brazing flux. Use Silver solder.
