Surface treatment for copper alloy

2006

We know that Alodine 1200S or Iridite are familiar surface treatment for Aluminium alloy. They both refer to the specification of MIL-C-5541. Is there any similar surface treatment for copper alloy and what is the specification?
There is a RoHS compliant passivation for aluminium based on trivalent chromium, which is SurTec and meets the specification of ASTM B921. Is there any RoHS compliant passivation for copper alloy and what is the specification?
