It’s gotten very expensive to silver solder, even with alloy rods. What are the parts for? An old friend remembered pulling silver dollars out of his pocket to silver solder.

Does anyone have experience with this product
Never saw fluxed rod in this alloy before - thanks for the link - so no experience.

56% silver is pretty common rod but the other metals in the alloy can significantly change the 'personality' of the process. I've never used it on stainless and it's liquidius temp is a little to close to the critical temp of 4130 to make it comfortable to use without some skill if you are trying to avoid HAZ. Also keep in mind that the high strength numbers quoted are for a very narrow range of gap in the joint.

If you don't need the convenience of the coated rod plain old BAg-7 should be cheaper and the local weld shop probably has it in stock. With the spot price of silver rising so much recently you might find a good deal on some old stock.

I've only used silvaloy, which is used for brazing refrigeration tubing, copper, steel to copper. Never tried it on stainless, and never used flux with it. Honestly don't know much about it other than it works good.
