Hydrostatic Work Hardening Question

[Bentwings]

Has anyone used or considered using one of the Copper Beryllium alloys? Information on the web claims 6 times the ultimate tensile strength of pure copper at room temp.

Properties	Metric	Imperial
Hardness, Rockwell B​	80.0 - 85.0	80.0 - 85.0
Tensile strength, ultimate​	1280 - 1480 MPa	186000 - 215000 psi
Tensile strength, yield​	965 - 1205 MPa	140000 - 174800 psi

From other charts on the web the Yield at 500 F is 140,000 psi which is roughly 10 times higher (or more) than garden variety copper. A very impressive copper alloy,...wonder what the cost is?

I would be very cautious working with beryllium . It the most toxic metal on the charts . Id say forget it altogether look for more conventional metals or redesign for greater strength.
