Hi guys,
Through a local DOD contractor I found a few small shops that will make Berillium Diaphrams... Apparently the new fighter jets use alot of the material, so they are set up to work with it, and do small runs... So , what I need, to get a price, is CAD drawings of the diaphram, and the piece that gets pressed into the middle.. I have been told that they can do it, based upon my description. So, did anyone ever make a drawing of the diaphram...or maybe please......mike...could you... Rich |

Copper and Copper-bronze will work harden. Beryllium won't. It's also over 30% more elastic than steel..... however it's NASTY stuff. If any of you DO decide to work with it be aware that absorbsion of airborne particles is a VERY serious health risk. :deadsmiley: IMHO it's more likely that the diaphrams were made from Beryllium copper rather than pure Beryllium. Beryllium copper is 98% copper 2% beryllium. B.C. is highly ductile which makes it great for forming complex stamped parts (see picture above) It's also the only copper alloy I know of that can be heat-treated. It is used for springs and such in specialized applications (it's light, doesn't work harden easily, and is a good electrical conductor). -Ben M. |
