New Answer: Although the definition does not include lead, most alloys of brass may have considerable lead in them. Lead is quite often added to brass to make it more machinable. Do a search on MSDS and Brass and 360 (or whatever allow you want to know about) and you will find the typical lead content listed. For example, alloy 360 will have as much as 4% of lead, hardly a negigible amount. Many modern brass alloys have extremely low levels of lead due to EPA requirements but unless one knows otherwise, you should not assume there is no lead in brass.

Original Answer: No - Brass is any alloy of copper and zinc
