    Alternative brazing

    Hey guys is there any other ways of brazing that do not involve the rising cost of the 15% silver rods and oxyacetylene gases. As you all know the cost of the brazing rods themselves have doubled in the past year. I've heard of using propane and oxygen or even map gas. I personally would like to find a cheaper brazing rod.

    Better still get dynaflow at half the price and very close to the same performance characteristics. I also like to use an acetylene air torch in lieu of an oxyacetylene torch kit. Thank you very much

    Dynaflow®
    Description: PhosCopper Brazing Alloy
    Dynaflow melts and flows at temperatures very close to Stay Silv 15, and provides comparable brazed mechanical properties. This makes Dynaflow an excellent cost effective alternative to the 15% silver alloys. This premium, medium range silver alloy has been meticulously formulated to even tighter specifications than our standard copper-to-copper alloys.

    Consumables

    Just wait till you price the 45% stuff ! It is sold by the Troy Ounce and was already 4 times more expensive than 15% rod.

    I say stick with 15% and Oxy/Acet and simply pass the increase on as "Consumables".

    Just like a savy Bar Tender can pour 32 "Shots" from a Fifth of whiskey (26 oz.) you should be able to cover the cost of the rod/gases + 20% on each Brazing job. That's not dishonest that plain business sense. A wise man once told me "Everyone has a right to make a FAIR profit" (emphasis on FAIR here) !

    I was working in the shop on Friday. My daughter ran past me with about $300.00 of 15 in her hands.

    I traded her for some cut up coat hangers. I think I'm good for a while.

    Like fuel you have to pass the cost on to the customer.

    Common sense isn't very common anymore.

    My turbo torch with #14 tip will braze up to 2 inch copper. I have oxy-acetylene on the truck for bigger pipe. Dynaflow is probably the best low cost alternative to 15%. I have used oxy-mapp and it works well. I have also tried the 0% silver (silvabraze) it doesn't flow like 15% dynaflow is much better and less brittle because of the silver content.
