ROHS compliant brass

I am trying to bid a job for c customer and he is asking if I can get ROHS compliant brass so that he can sell his product in Europe and Asia. I have hit the internet and made a few phone calls but can't seem to find a straight, consistent answer as to what brass alloys I can use for this job. I am ooking at C260 sheet, C330 tubing, and C360 rod as the primary alloys. I found a website with a pdf that said lead was allowed up to .4% as an alloying element in copper, but what about brass (or do they consider brass a copper alloy)? Also, are there any places in the US that sell ROHS compliant brass with paperwork?

Thanks.

Geof will become famous soon enough

Brass is a Copper alloy in which the main alloy element is zinc.

You should be able to find some information if you keep searching. I did a search a couple of years ago about leaded steel and the 0.4% lead content being okay rings a bell.

I believe that ROHS regulations allow up to 4% lead content in brass alloys. Anyway 360 brass has a fairly high lead content, this is why they call it ultra machinable brass, the additional lead helps it machine easier. This was copied from a site that I googled real fast.

"Are there exemptions? There are some exemptions that your products may fall within. For example, brass, an integral part of most electronic devices, may contain up to 4% lead. Most products manufactured by MILL-MAX have a base material of brass. Therefore, the raw material for MILL-MAX products is exempt from the requirement to be lead-free."
Here is the actual link http://www.mill-max.com/rohs/general_info.cfm
Here is some other info.
"BRASS 360
Typical Analysis in Percent:
Cu 60.0 - 63.0
Pb 2.5 - 3.7
Fe .35
Zn bal."
Heres the link http://threaded-rods.com/alloy_360_brass.htm
Hope this helps.
