Brass has higher malleability than bronze or zinc. The relatively low melting point of brass (900 to 940 Â°C, 1652 to 1724 Â°F, depending on composition) and its flow characteristics make it a relatively easy material to cast.o enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a lower melting point than the other constituents of the brass, it tends to migrate towards the grain boundaries in the form of globules as it cools from casting.
