Yield stress selection 1

[freelegend]

I am doing eletrical magnetic force calculation for bus bar design. In order to determin the maximum span distance between supports, the maximum bending stress have to be calculated and it should not exceed yield stress of the material (c10200 copper). My question is is there any difference of yield stress between annealed copper and hard drawn copper? which yield stress is larger?

Thanks in advance!

Visit the materials database below and you can evaluate C10200 mechanical properties first hand under various cold worked conditions;

Here is a more direct link to C10200 in the H00 temper in this database

Thank you very much for your quick reply, metengr!
I have few knowledge of materials. Following the link you provided, I was directed to:

what is the difference between H80(40%) and H55 (15%) for c10200? Thanks again for your help!

The temper designations for wrought copper and alloys are defined in the ASTM standard below, if you have access to one

http://www.astm.org/Standards/B601.htm

If you don't, you can Google copper temper designations and find some of this information defined, as below

Many many thanks! Now, I think I know how to choose the right yield stress for calculation. Appreciate your time and help.
