Common names: 60/40 Brass (Lead-Free)
Muntz Metal
Yellow Metal
A copper-zinc alloy with a duplex alpha-plus-beta phase structure and excellent hot-working properties. Service environment must be considered to predict corrosion behaviour. Cu Zn40 has somewhat better cold-working and joining properties, but is less readily machined, than the similar low-leaded alloy Cu Zn40 Pb. The most commonly used wrought forms are plate, rod and sections/shapes.
