Electrical conductivity values of oxidized BeCu


(1998)

Hello
We use electroplated gaskets and chassis for our computers.

Most of our computer chassis are made of zinc coated steel and the linings and gaskets are made of BeCu, tin or stainless steel. We often see oxide formation due to galvanic action at the junctions. I am trying to find out the electrical conductivity of the oxides (or the impedance offered by the oxide layer).

Since the mechanism and composition of the oxide formation are so well understood and well documented, I am guessing the electrical properties must be recorded somewhere.

Could anybody tell me from where can I get the conductivity information?

Thanks

Hi, Sudip. Letters 39394 and 32648 are at least a good start for your situation. Good luck.
