Can braze cast iron exhaust manifolds. SSF-6 is high-strength 56% silver solder rod. The rod of choice for air conditioning applications (HVAC), copper plumbing, automotive, hospital, restaurant, gun repair and jewelry-making.
If you need a high strength joint between stainless steel and another material (thin parts) etc. this is probably your best bet . The rod is covered in flux and easy to use , with good end results. Just prep the parts ,and follow the instructions precisely ,and you'll have a good joint. I've also used other muggy weld products with great results. A little pricy but you get what you pay for.
We used this to braze a 304 tube assembly. One bent tube, a fitting on one end and a flange in the middle. The material flowed like water and was very strong.
It seemed a bit pricey, but after using it, those thoughts are gone.
Great product, would recommend highly and will buy again.
