Bearing yield strength of oxygen-free copper

Bearing yield strength of oxygen-free copper

Bearing yield strength of oxygen-free copper

(OP)
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.

RE: Bearing yield strength of oxygen-free copper

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.

RE: Bearing yield strength of oxygen-free copper

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.

Here is some leads to the bearing qualities of OFHC. Check the authors and articles sited in the copyright notice.
