Harris Safety-Silv 56% 1/16 Silver Solder Brazing Alloy 1 Troy Ounce, 75310 5631

Have used this Harris silver solder for years. Perfect results every time

Harris is a known brand: dependable quality--no surprises--it is what it says it is. With a little practice almost anyone can learn to silver solder. The secret is metal preparation, the use of the right flux, and rapid rise in temperature to red glowing hot. Propane is hot enough--the technique is to get the proper amount of heat to the metal to be soldered and not to use oxy-acetylene which will likely burn up the flux before soldering temperature is reached. Use white flux for small jobs and black flux for larger jobs which will take longer to heat up.

Used to braze a stainless line to a hard copper elbow. Used with black flux, worked perfectly. I used oxy-acetylene with a reducing flame. Focused on the stainless but the copper was red. Flowed easily uphill into an imperfect joint and sealed on the first attempt.

Fantastic price

Good stuff. Expensive. But its silver so thats the way it is.

You get what they say. Others will cheat you on amount of silver in the silver braze.

This is the problem solve braze filler for joining many metals. It flows like water, almost being eutectic. And wets easily thanks to the 56% Ag. Yes, pricey but this isnt for making fillets, it is for flowing into tiny joints and acting as a solder. Been using this type and brand for 25+ years. Just cannot justify the gamble with off brands. I dont go through much, this troy ounce will last at least 10 years unless Lady Luck throws more high dollar miracle jobs in my reach. It is easy to use..joints need 5 to 10 thousandths of clearance. Use Harris flux, white for most and black for stainless. Either GTAW or oxyacetylene with just a frogs hair of reducing flame. Throw the heat on the larger of the side of the joint, then touch the filler to the smaller part. When its hot enough, it will flow like magic. The joint is a hint golden which to me is pure beauty. Very tarnish resistant except to halogen salts or sulfur compounds. Proper joints will just show a line.

Expensive but works very well. I did buy flux which is required but this stuff is extremely strong and wicks well.

Absolutely heavenly in repair food production machines copper pipes and fittings for hot water.

This solder comes in a nice plastic can. It should be 31 gram of it, bit I have measured 32.5 gram - not a bad deal. The solder is in the form of 1/16 diameter wire coiled for convenience. It measures .062 in diameter. I did not try it yet, but hope it will work with Harris black flux and propane torch.
