Strength of brazed copper tube

Strength of brazed copper tube

Strength of brazed copper tube

Are there any ways to estimate tube/pipe material strength after brazing operation?
The application I am looking may require a section of thick walled H80 copper tubing, and the joins to a brass block by brazing.

I am aware that brazing basically anneals the material, causing it to have lower strength overall. Would it be safe to use the numbers (to calculate wall thickness) for an annealed temper, e.g. OS050?

Any insights or pointers for further research is welcome.

RE: Strength of brazed copper tube

What type of strength are we to respond to? The cliché in this forum is the more information the better.

RE: Strength of brazed copper tube

It's the yield strength, which will be the reference limit for stress calculations.

RE: Strength of brazed copper tube

Assuming a properly sized lap joint and clearances, the shear strength of the braze metal will govern the strength of the joint.
