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.
The silicon melt temperature was measured for 30 min. The temperature variations at the melt surfaces and bottom with the temperature of crucible top and bottom being 1450Â°C and 1430Â°C are shown in Fig. 4. The concentrations of boron added are non-doping, 1Ã10 18 and 1Ã10 20 atoms/cm 3, respectively.
