Difficulties Silver Plating on Cast Aluminum
We routinely manufacture machined Al 6061 and silver plate with no problems. But, when we go to cast parts, the plating does not survive a 250 F bake without completely blistering. Currently we use an undercoat of zincate, a coat of copper and finally silver. We cannot tolerate nickel for electrical reasons.
Is there something special we need to do to cast parts to get better adhesion?Richard Scott

We have a lot of experience plating silver on to cast aluminum for RF products. We do not use a nickel undercoat and do not have blistering after baking at much higher temperatures than 250 F.Brad Smith

We have exactly the same problem Richard has. Can you please send me some more info how you solved the issue.
Your quick response would be appreciated.
I hope you still can get this e-mail to reply to an old issue dated 2001 :))
