ALOCHROM 1000 RoHS Compliance

We have recently been informed by one of our plating vendors that ALOCHROM 1000 (using hexavalent chrome) is not RoHS compliant. On the other hand another plating vendor has informed us that the process is RoHS compliant because the amount of hex chrome left on the part is below the emissions level.

There seems to be no uniform opinion as to what the current situation regarding Alochrom 1000 is with regard to RoHS compliance?

Mike,

If you look at Ltr. No. 40022 you will see that this question has already been debated. There does not currently appear to be a clear answer about the interpretation of RoHS as applied to Alocrom/Alodine/Iridite.

Your best bet is to talk directly with the manufacturers and get their considered opinion.

Alternatively, why not look at the RoHS compliant conversion coatings that are now on offer as you will not then have to worry about whether you meet the requirements?

End of the day, you have to be convinced that the material you are using is compliant as, if it came to it, you would have to argue your corner in a court of law and it is no defense saying "I thought it was".
