Hardware performance and RoHS

As an end user of products that will be affected by these changes, can anybody give me information on any effects on the mechanical performance of hardware using these alternative coatings. I understand there will be some deterioration in corrosion performance, but what about torque retention and fatigue performance?

I'm a supplier engineer Sun Microsystems. My company designs low to very high end servers housed in 1U to large complex enclosures.

The finish on our enclousures is specified as: Zinc plate per ASTM B633-85 Class Fe/Zn5, Type III clear,bright

My question is in regards to complying with WEEE and RoHS requirements by eliminating Hexavalent Chromium.

When changing plating on enclosures from Hexavalent Chromium to trivalent Chromium does the electrical characteristics of the enclosure change in regards to EMI (electrical magnetic interference).

Thanks
