Can C365 brass Muntz metal be silver brazed?

I have a project out of C365 brass that would be far simpler to construct if I could silver braze part of it together rather than machining it out of one piece. Any one done this? I have my doubts since I see it has some lead in it. Haven't bought the material yet so have none to try a sample with.

Well, according to Google, it can be brazed:

Silver brazing may be higher temperature than normal brazing, though. But since C365 is essentially leaded C280 Muntz metal, why not just use Muntz metal?

Silver brazing alloys come in many flavors, with different melting points. Items made from several parts to be brazed together in separate stages take advantage of that variety. The first assembly is brazed with "Hard" brazing material, the highest melting point. Then a second part can be added on using "Medium" alloy. A third part can be added using "Easy" alloy and there is a possible "Very Easy" alloy for a fourth add-on. These are jeweler's technical terms of art, applied to both gold and silver solder, the term most used by jewelers for their vocational brazing alloys. But general industrial silver brazing alloys share the same variety of alloys and melting points, with other variations in toxicity, strength and preferred parent metal.

I'm no expert, but I've silver brazed a lot of C360 leaded brass with no problems so far.

Plus1 to both the above posts. Lead is not the problem, too much aluminum can screw stuff up though. Copper & Brass sales rates C360 with way more lead good for brazing. Attached;

Good luck,

Copper Development Association rates it as "good" for brazing.

Thanks all, looks like I will give it a try.

Go with a low heat braze...which I think is the 56% silver braze. Personally, I like the black flux better than the white flux for silver brazing.
