"Is Galvanneal RoHS compliant?"
Q. I'm trying to find information to determine if Galvanneal is RoHS-compliant. If is it not compliant, does a replacement exist? I just started reviewing mechanical components and conducting research for our RoHS compliance effort and have no background in this area. Any and all info regarding substitutes and alternatives for noncompliant materials would be greatly appreciated. Thanks.James Favreau

A. It is my understanding that all precoated steel finishes such as Galvanneal and such are sealed as a final treatment in a hexavalent chromate solution which would make these materials NON-RoHS compliant. At least one large computer giant has told me that they discontinued use of such pre-coated materials and have switched to using thin electroless nickel until a suitable alternative is established and qualified.

A. Update: There are companies that are now making a "RoHS-Compliant" version of "galvanneal".
One company that I spoke with called "USS-POSCO" was extremely helpful and friendly. They sent me all sorts of PDF files on their products, including a "letter of RoHS-Compliance". You can reach them at: www.ussposco.com/Products/Gal_Desc.shtml
Another company that I came across while doing my search is called, "Pacific Toll Processing" and can be reached at: www.pacifictoll.com/page5.html
Then finally, there is another firm called, "ArcelorMittal" and you can find them at: http://www.dofasco.com/bins/doc.asp?rdc_id=263078
I hope this helps anyone who is seeking to know about galvanneal being RoHS-Compliant!

Q. Is there any update to this information? Is it realistic to say that galvanized material manufactured today is ROHS compliant or should it be part of the purchase order that ROHS compliant Galvanized or Galvannealed material be used?R. Webb

A. Hi, R.
I definitely would not trust galvanized or galvannealed material to be RoHS-compliant unless you spec it that way. Good luck.
