Bearing yield strength of oxygen-free copper

[dcopps]

I am seeking the bearing [yield] strength of oxygen-free copper (specifically C101 and C102). I have not been able to find this information in the ASM Handbook or Aerospace Structural Metals Handbook. It is a bit of an unusual property to be after, according to my engineer. Thanks for any help you can provide.

dcopps;
I also drew a blank in terms of locating specific data sources on bearing strengths for copper. I see two options for you;

1. If the application, which you did not mention, requires a real value to assure safe or reliable operation of equipment, you probably need to have a mechanical lab run a bearing stregnth test to simulate your application.

2. If all you need is an approximation for calculation purposes that includes a safety factor or a design margin, I would use (as a first approximation) 0.57* tensile yield strength = shear yield strength.

We used these alloys for gaskets in two of our process. The company that made the gaskets doesn't exist as an enity anymore. Our engineeering standards had a lot of information about both alloys and I'll see if I can get someone to pull the data. We used both materials in the annealed and the 1/4 hard materials. The annealed was in high pressure service and the 1/4 hard was in a high temperature service.

Here is the physical database for the above mentioned alloys. There is considerable difference in the physicla of your two alloys.
