Silver solder

[Drej]

Dear group,

Does anyone have any idea as to the mechanical properties (Young's modulus and Poisson's ratio) of the silver brazing alloy AG14 (other designations M25T BS 1545:1984) or anywhere close to this chemistry. I have looked high and low for these and cannot find them anywhere. Any approx figures appreciated.

Cheers,

If you haven't already looked at Handy & Harmon's website, you might give it a try.

In some brazed joints, there is sufficient diffusion bonding of the joined metals/alloys that the braze filler alloy essentially can be ignored with respect to the stiffness of the new assembly. In other words; the parent metal/alloy modulus(i) would govern the modulus.

But maybe you have a condition that actually requires understanding the contribution of the braze stiffness or maybe you are trying to work the braze alloy?

We have looked for this type of information and never found it.

AG-14 is Johnson & Matthey’s designation for what the American Welding Society calls BAG-24.

I have the ANSI/AWS A5.8-92 Specification For Filler Metals And Braze Welding and it doesn’t have any of this information.

This is a sales arm of Handy & Harman. These guys are really good.

The problem is that the properties of braze alloy in a joint are so dependent on how the alloy is used. We have information about this on our web site at
