Ken Ken Ken....  Get this straight, and everything becomes clear..

RoHS is not about protecting the environment, or anything actually important...

RoHS and such things as Lead-Free, are about APPEARING to be environmentally wonderful.

A world class expert in metal finishing, Jack Dini has been writting a column in a monthly mag about this very weirdness for years...  There is a book out which is a collection of his columns that is a national treasure.

Many of the chromate conversion suppliers are coming out with non-chromate containing conversion coatings to replace the old ones.

In one aspect of this that I am involved with, finishing aluminum castings, it was shown that because the process now involves a completely different kind of painting... electrophoretic, they could dispense with the coating altogether.

Hi Phil,

You beat me to the punch. I was going to as almost the same question.

What is the aerospace industry going to do about conversion coating on
aluminum? It seems like if the RoHs was smart they'd try to control the
processing and not the end item. I can't imagine that once an aluminum
part is conversion coated that it would be much of an issue to the
environment. But then what do I know, I'm certainly not a Political
figure in the EU who has all the answers ;-)

Subject: [TN] Off Topic? - Hex Chrome plating replacements

Good morning,

I'm not sure if this is the right group to answer this, but here goes
anyway.

As we move forward with RoHS complaince the question of plating steel
and aluminum come up repeatedly. Currently we use Gold Irradite on our
aluminum and Yellow Chromate on steel.

What is the industry switching to? The clear versions of these?

Thanks in advance,

Phil
