Lead in copper alloys is allowed under RoHS up to 3% lead. Lead is used to
make brass alloys easier to machine. If the copper alloy is a homogonous
material then that material can have up to 3% lead in it. As long as all the
other materials are lead free then the complete product meets the
requirements.

You need to get clarification of where the lead containing copper alloy is.

Kelly,
        If they are telling you they are compliant EXCEPT for lead in

I am trying to verify RoHS Compliance for our inventory. I have a
question about a response I got from T&B. Their answer for many of their
products is "Compliant under RoHS except lead in copper". Can anyone
tell me if this is truly OK under the directive? Thanks for any help on
this.
