Out of the Mcmaster Carr catalog (they have other options as well):
Ultra-Machinable Brass (Alloy 360)
The standard by which copper, brass, and bronze machinability is measured, Alloy 360 is also known as free-machining brass. Its lead content prevents successful welding but does provide lubrication to enable high-speed machining such as drilling, milling, and tapping with reduced tool wear and breakage. Alloy 360 is corrosion resistant and has a smooth finish that readily accepts plating. Not heat treatable.
